We call these Remote Speaker Mics (RSM) and they have come in all different shapes and sizes over the years. Normally a staple of the emergency services, but we have seen a upsurge in general radio users using RSMâs. So it comes as no shock to us that a pro-active company like Imtradex has designed one to suit the needs of the masses.
What was originally developed as a handheld microphone for digital radios, has blossomed over the past few years to an essential equipment accessory for digital radio standards of emergency service: The Aurelis hand microphone from Imtradex.
Meanwhile with the Aurelis, the specialist for critical communications, have a whole series of hand microphones on the market, all adapted to the specific challenges of the communication in critical applications of security agencies, fire departments, dispatch and emergency services. The Aurelis series addresses the different needs of the user: based of the basic model Aurelis Base, Imtradex manufacture customized versions that are specially tailored to the range of functions that meet the customerâs requirements.
All the Aurelis hand microphones have a send button, a microphone and high quality speakers. âAll devices contain a cable attachment and also the possibility to connect external audio accessoriesâ adds Ralf Kudernak, CEO of Imtradex. Depending on the radio, different data applications can be integrated, so can ex. on the model Aurelis AudioDis, information be displayed on the LCD display.
âThe youngest member of the family is the Aurelis USB handheld microphone, which is designed for connection to computer-based communication system, especially for control centersâ informed Ralf Kudernak. âThe USB interface gives the easy integration and can be connected independently to each operation system and used with existing hardware. With the development of the Aurelis USB, we followed the desire of several control centers, which wanted to use a handheld microphone which you can also hang at the table of the workplaceâ said Kudernak.
In terms of digital communication, security and flexibility the innovative ultra-lightweight Aurelis Nexus PTT set new standards. It was specially designed for fire fighting. Thanks to it extra large PTT, with short sensing path and exactly defined pressure point, the operation with use of working gloves is possible.
The user can also be flexible in their choice of radio and headset: All Aurelis handheld microphones can be combined, not only with many headsets, for example with the monaural neckband headset from the NB Series. They are convenient and safe to wear, provide a maximum safe mobility and provide an excellent voice quality. Imtradex can also build them with the different connectors required, so they can easily be connected to different digital radios. All Aurelis handheld microphones have a robust plastic housing. Is splash-proofed and protects the device against dust and against temperature influences, so they can be reliably used in a temperature range from -30 to + 70 degrees Celsius. The 180 gram lightweight Aurelis handheld microphones are also available in different colours and optionally equipped with a car holder or cloth clip.

Motorcycle helmet intercoms have recently gained lots of popularity for the safety and convenience they offer. They have lots of enhanced features which help riders focus on driving. That being so, you should know that being able to choose and use the right type of motorcycle helmet intercom is extremely important as it makes it easy for riders to perform all kinds of actions and do all kinds of things without any fear of losing control of their motorcycle. In this article, we’re going to be talking about the best features to look for in a motorcycle helmet intercom, and the different types of motorcycle intercoms available in the market;
Here are the features to look for when looking for a walkie talkie headset for your motorcycle helmet:
Well, riding in a motorcycle usually makes the rider quite vulnerable to various kinds of road and environmental factors. This includes dirt, dust, rain, humidity, and all types of things which one can possibly encounter. Because of this, you should consider getting a completely weatherproof motorcycle helmet intercom. Fortunately, most of the motorcycle intercoms in the market today are weatherproof, water resistant or waterproof. For the best protection from the elements, consider choosing a weatherproof or waterproof intercom, instead of the water resistant ones; this ensures that despite any hazards and rain, your system will be safe, and still work efficiently.
You should also consider getting a system that has a headset speaker for both ears or one ear. This particular factor depends on personal preference as some may find it more convenient to use a one ear headset, while others may prefer both years as some riders like hearing sound in both of their ears. That being so, you should know that installation and moving of the intercom to a different helmet is much easier for the systems which have only one ear.
Another important factor to consider is voice activation. Many systems have the voice activation feature which keeps the headset(s) quiet when no one is talking. The voice activation feature also has the ability to get disabled and a push to talk switch feature can be used instead. Apart from that, sound quality and noise cancellation is something you need to put into consideration. Many motorcycle intercoms have the noise reduction feature with digital signal processing which helps reduce the noises/sounds they pick up from your microphone; this feature is especially important if you are a fast rider.
For those who like riding with some music playing, you should consider going for the motorcycle intercoms which come with either a built in FM stereo, or an auxiliary stereo input for iPod, a Walkman, MP3, or a satellite radio unit. This type of input can also be used to receive driving directions from voice prompted GPS unit.
There are some motorcycle intercoms which can be mounted in your helmet, on your belt clip, on your bike or even put directly to your ears; this usually depends on just how big or bulky the intercom is. Choosing this feature depends on personal preference. You should choose the one that you’d be most comfortable using.
Last but not least, connectivity for cell phones is another crucial factor to consider when choosing a motorcycle intercom. This feature allows you to access the phoneâs features while you’re on the road. The feature is best paired with hands free operation.
Without a motorcycle intercom, riding can be a very solitary experience. Using an intercom is a great way of clearing your head and putting your thoughts together when you’re riding alone. However, if you’ve a passenger, or you are biking with another rider, sooner or later you’ll want to converse with them. A motorcycle helmet intercom will let you do this, and so much more.
That being said, the problem is that there are very many motorcycle intercoms to choose from. And given the fact that motorcycle helmet intercoms need to work in extremely difficult environments, choosing the best one can mean all the difference between enjoying your ride and hating it. Below, we are going to give you the different types of motorcycle helmet intercoms available, to help you make the best choice for your particular needs;
Acoustic Motorcycle Intercom
This is the most basic form of the motorcycle helmet intercoms. With this type of intercom, there are no electronics involved since it uses hollow tubes which have rubber tips that are normally inserted into the rider’s ear. A different tube is used as a mouthpiece for talking into, and they both connect through a junction box. This system simply uses the hollow tubes which the voices travel through.
One of the main benefits of a walkie talkie headset is the fact that you’ll find no batteries to mess with; this makes them highly reliable. However, there is no amplification which means that there is no way of regulating or adjusting the volume or filtering the wind noise. therefore at high speeds, it’ll likely be much harder to listen to. Another issue with this system is the fact that many riders tend to realize that the ear plugs are uncomfortable in their ears for an extended period of time. These acoustic motorcycle intercoms only work with driver to passenger and not bike-to-bike.
Wireless Intercom Technology
This is a most complex and technologically advanced system as it utilizes different forms of radio technologies namely FM, GMRS, FRS and Bluetooth.
FM (abbreviation for Frequency Modulation) is widely used because it’s very efficient when it comes to transmitting clear sound, however, if it’s used by driver to driver, its’ performance isn’t good if they’re too far apart. It is quite similar to the FM radio you normally listen to, however for the motorcycle intercom, a much narrower frequency is usually used. The FM intercoms work best when there aren’t any kind of obstructions (like hills) between the receiver and the transmitter.
If long range is the most important feature, then the GMRS Walkie talkie headsets will offer a much better performance. The FRS (abbreviation for Family Radio Service) and GMRS (abbreviation for General Mobile Radio Service) are the modern equivalents to old walkie talkies you might have used during your childhood days. The FRS intercoms typically have a maximum range of 2 miles provided there are minimal obstructions in between, while the GRMS intercoms can effectively communicate up to several miles. Just Like the FM, these two are public frequencies which means other people can get to hear your conversations, and vice versa. In some heavily populated areas these FRS/GRMS radios are heavily used, while out on the open road you should enjoy fairly private conversations.
One great thing about using the FRS or GMRS walkie talkie headset is that you can visit Headsetonline and purchase a walkie talkie headset and handheld radio which you can use to contact these units. In case someone is following you in a car, or they have a wired intercom system which allows them connect to an FRS or GMRS handheld radio, they will be able to communicate with you. The only downside is that you’ll find countless of these radios in the heavily populated areas and you’ll end up picking up lots of other transmissions.

Now itâs not the usual field that we cover, but it hit our radar. How many times have you seen an enthusiastic presenter or an excited contestant on TV drop their radio mic and crawl around on the floor, trying to pick it up! Well when a costume designer and a sound man get together then things get designed, and why this hasnât be invented before is beyond us, but it looks like an idea that could take off. Read the full article here.
Sound recordist Simon Bysshe and costumier Laura Smith have combined their knowledge and expertise to create URSA Straps, a unique range of low profile body worn straps designed to conceal radio microphone transmitters.
Officially launched this month and now available in the UK and Europe, URSA Straps are made from a specially developed bonded fabric that is ultra-slim and provides excellent stretch, comfort and breathability. Each strap incorporates a pouch to keep the transmitter locked in place and a cable pocket for managing excess microphone cable. URSA Straps are available in black, beige and brown skin tone colours and can be worn around the ankle, thigh or waist.
Bysshe and Smith developed URSA Straps after listening to numerous artists express discomfort while wearing radio mic straps. Traditional thick neoprene or elastic straps can irritate the skin, become soaked in sweat and are often impossible to disguise under figure hugging costumes.
âIt was obvious that a better way of discreetly securing transmitters was required,â Simon Bysshe explains. âAs a boom operator I had worked with many artists who disliked wearing transmitter packs because their associated straps could restrict movement and become uncomfortable. In some cases they had simply refused to wear them.â
Laura Smithâs knowledge of costume making proved invaluable as she was able to construct prototypes and identify the exact fabrics required to suit the needs of costume, artists and sound departments.
âAfter many months of research we decided to create our own unique hybrid fabric by fusing two stretch fabrics together,â Bysshe explains. âThis resulting fabric is just 1mm thick and much lighter and softer than any other fabric of its kind. Crucially we incorporated a hook Velcro compatible outer surface that allows the straps to be securely attached to themselves at any point.â
Bysshe tested the new straps while working on the second series of Sky AtlanticâsÂ The Tunnel. Lead actress ClÃ©mence PoÃ©sy was an immediate convert and provided valuable feedback to help develop the product. Bysshe has subsequently used URSA Straps on the third series ofÂ Peaky Blinders. The USRA Thigh straps were particularly popular with the cast members who found them secure, light and comfortable. The fact they can be worn around the thigh as opposed to the waist made them invaluable for use with the period costumes.
âWith URSA Straps we have created such a comfortable low-profile solution that artists often forget that they are wearing them. Now we have to make sure that actors remember to take them off before they leave!â Bysshe adds. âThe straps can be washed and re-used every day for many months. Our Thigh straps are particularly popular as they are designed to not slip down the leg. We achieved this by bonding on a strips of Polyurethane gripper to the inside of the straps.â
Outside film and television, URSA Straps are also proving popular with dancers who need to receive audio cues during a live performance. Using waist or thigh straps the sound team can easily conceal a receiver pack on their bodies without restricting movement or compromising the look of their costumes. URSA Straps have also developed a Double-Pack strap allowing artists to wear two packs on one strap.
Oscar-winning production sound mixer Simon Hayes was an early adopter of URSA Straps and describes them as a total game changer for his team.
âURSA Straps allow us to rig radio mics on costumes previously thought to be unmicable. Tight dresses, sportswear, stunt harnesses â they can all be easily miked using low profile URSA Straps. These straps are so popular with the actresses I work with that many have asked to keep theirs at the end of the production.â
URSA Straps are suitable for a variety of wireless transmitters including Lectrosonics, Zaxcom, Wisycom MTP40 and Sennheiser 5212. Two different pouch sizes are available to ensure optimum fit. Three different waist sizes are available: small, medium and large.
âInitially Laura and I were making the straps by hand in our garage,â Bysshe says. âWhen we realised their potential we scaled up production by taking on two experienced manufacturing firms in Leicester. Our launch has been a huge success with orders coming in from all around the world! We are now on our third large production run and expanding our market into Theatre, Concerts and Outside Broadcasts.â

SO youâre walking down the street and suddenly the music kicks in, you drop to the ground and pull your earphones out of your ears! âwhat just happenedâ you think, then you realise the un-pause on the mp3 has just kicked in and you forgot to turn it down. Well people this will be a problem of the past with these earphones, Now all I need them to do is make coffee. VERY IMPORTAN You can find the original article here
Whatâs been your favorite set this weekend? Or the best new track youâve shared with all of your friends? Well take that track and imagine listening to it in exactly the way your ears want you to.
Meet theÂ EvenÂ earphones, who tune themselves to each personâs particular hearing. At just under $100, they customize the sounds they play to suit your own audio needs. They use their own EarPrint technology that measures how you hear different frequencies, then sets the earphones toÂ play back sound specifically for each ear. As a result, theÂ headphones give you aÂ profile tuned to your own ear (each ear with its own profile).
One of the biggest things that originally drew me to the earphones was the fact that they are not a pre-order campaign â they have physical earbuds available now. The company, whoÂ launched in in June, has sold out batches twice thus far and are continuing to take orders on their website. Luckily, I was able to get my hands on a pair to try out as well.
Iâm pretty picky about the gadgetsÂ I use for audio, as Iâm constantly listening to music â digging for new sets on Soundcloud, reviewing new tracks, jamming outÂ in my own world. Being able to plug in and listen to my own musicÂ isÂ what allows me to focus and, as a result, Iâm very specific about the type of earphones or headphonesÂ I use. That being said, I was overly ecstatic when I was handed a pair of Even earphones to try out.
First, their appearance: the cords are aÂ high-quality string that have a smooth look and feel. The budsÂ look sleek, with a simple black-and-white color scheme â one black, one white, with the EarPrint device hanging at the middle of the cord, meant to dangle at your chest. They donât tangle easily, which makes them easier to carry without having to worry about dealing with knots. Theyâre the type of earphones I wouldnât mind wearing out in public.
Next: the sound test. This is where we meet âSarah,â the soothing female voice that guides you through a number of sounds to test where your hearing level is at. This test was very straightforward â Sarah literally starts by saying âHi, this is really easyâ â and felt very conversational as sheÂ talked you through each noise. Five pieces of music are played for each ear, and youâre required to hit the button once you hear the sound. Though the process takes a little bit longer than Iâd like, itâs seamless.
Overall quality of the listening experience was great. I switched between my Bose over-ear headphones and the Even earphones to test the difference in sound quality and worked to try a few subgenres of electronic music to see how each would sound between both pairs. I started off by listening toÂ Louis The Childâs set from Lollapalooza this yearÂ and instantly found that the vocals were much more emphasized than in my Bose headphones. Next, I moved on toÂ Mikey Lionâs live set from Desert Hearts 2016Â andÂ lovedÂ the emphasis on the bass I was hearing â the Even earphones made it much more of an all-around experience. I then switched over to Troyboiâs tracksÂ Do You?Â andÂ O.G.Â to continue to test this bass theory and, again, Even delivered.
As my hearing is likely damaged based on the amount of festivals and shows Iâve attended over my lifetime, it was much appreciated that the earphones were able to pick up on the frequencies I have more trouble hearing to create the full experience tracks deserve. Interestingly enough, every time I switched back to my Bose headphones to compare, I had to turn the volume down because it came at full blast and was overwhelming â and, when I did, the clarity between vocals and bass was lost. All in all, these babies pack a punch with their sound quality when it comes to electronic music.
Itâs refreshing that these earphonesÂ donât require using an app, since that seems so commonplace nowadays. All of the information that goes into your profile is saved in the little box hanging onto the string, so you can plug them into any device â phone, laptop, iPod, whatever you want â and still have your own profile saved. I found this extremelyÂ helpful, as it meant that I donât have to re-adjust my volume based on what device Iâm using. Beyond that, itâs a refreshing change from listening to sets with friends and having to change the volume based on everyoneâs sensitivities. It makes listening much simpler and, quite frankly, electronic music better. How could you say no to a custom-made, surround-sound system in your own ears?
To get you started, here a few sets, old and new, you may enjoy listening to in the earphones (ok, to be fair, these are sets thatÂ IÂ would want to hear in them):

The good old walkie talkie will still have a place in most businesses, but Motorola being a technology company they are always innovating, they are underpinning their future communications on data, currently date networks cannot cope with this but as the technology grows, Motorola will be able to produce handsets, motorola accessories and communications that will seamlessly use this without any problem, we look forward to the future.Â
Motorola Solutions CTO Paul Steinberg explains how data and enhanced communications can make cities safer â even if theyâre not smart just yet
As CTO of Motorola Solutions (MSI), Paul Steinberg says he has three broad remits.
The first is to advance the companyâs technology with his team of engineers and data scientists, the second is to drive its patent strategy (âWhat patents we get and what we do with themâ) and the third is to invest in startups so MSI can get access to something it doesnât have.
âIt keeps you humble because thereâs always someone else doing things faster and better than you,â he tellsÂ TechWeekEurope.
Motorola Solutions now only deals with public safety communications systems. It was spun off from the Motorola Mobility handset business that was sold to Google (and later Lenovo) in 2011 and sold itsÂ handheld computing division to Zebra Technologies in 2014.
This might seem like a very narrow focus but itâs a market in which the present day Motorola senses a great opportunity as emergency services update their infrastructure to improve service and cut cost.
In the UK, MSI is working withÂ EE to help deliver the Â£1 billion Emergency Services Network (ESN) â a 4G platform that will allow for data-enabled services alongside critical communications â and save the government Â£1 million a day
These upgrades will power what MSI sees as the big trend in public safety: the coupling of communications with data analytics, a vision it recently outlined at Critical Communications World (CCW) in Amsterdam.
â[Mission critical communications are] every bit as important as they have been and we expect [them] to be tomorrow,â explains Steinberg.
âMission critical intelligence brings in connecting things â data. It becomes more about context and situational awareness. The investments weâre making are more in that direction.
âOne of the things weâve been working on is the connected first responder. What we did was we built a context engine thatâs at the heart.â
The âcontext engineâ built by MSI brings together various different inputs. For example, Bluetooth connectivity can unite weapons, body sensors and imaging equipment to give a police force a greater overview of a situation.
Steinberg explains a scenario where if the context engine detects a weapon has been fired and a policeman is not at a station or at a firing range, their video camera will automatically switch on. Other situations could give a paramedic of firefighter additional information, possibly through wearable technology.
âWhy did we do the Context engine? âEyes open, hands freeâ: keep focussed on what youâre doing and keep your hands available to do what you need to do,â saidÂ Steinberg.
âWe envisage this working as an ecosystem with well-designed interfaces around the core context engine. We see ecosystem partners offering applications and hardware. And some pieces of those we will offer as Motorola. We see it increasingly as a software problem.â
Steinberg favours acquisitions as a way of advancing his goals and MSI has venture capital operations to fund the third part of his remit. MSI monitors the development of numerous early stage companies with a view to boosting its own business.
â[Takeovers] give us technology or a skillset that we canât do properly [ourselves],â he explains. âIf the concept looks like it has legs, thatâs when we make the decision. In some cases we donât proceed.â
Sometimes the target is more established.Â MSI has bought Airwave for Â£817 million, a move which it is believed will help accelerate the transition to next generation systems. Airwave currently powers the pre-ESN communications capability of the UK emergency services and Steinberg sees the acquisition as a method to migrate customers rather than innovate.
âIt brings us another data point but it doesnât really change how my team works,â he says. âItâs a company that helps us ensure we have an orderly migration.â
Smart cities and smart vehicles
MSI says the Context Engine and its vision of data-supported communications will be strengthened by theÂ parallel development of smart cities;Â even if itâs too early to have any impact right now. Steinberg describes âshotspotterâ technology capable of detecting when and where a gunshot is fired, aiding emergency services, and believes smart cars will also play a role.
âI think as the city becomes smarter, we can benefit from the environment,â he predicts. âWe can fuse that together and help facilitate real time decision making. The next mobile platform is the vehicle. I think that will create some interesting opportunities for us.â
But the very nature of emergency services means technological jumps are not to be taken lightly. A technical hiccup can mean the matter between life and death and although political reasons might have delayed the transition to LTE, concerns about reliability will have played a role too.
Steinberg agrees and is adamant that no matter what advances are made, MSI will not jeopardise the basics.
âThe foundation of our business is communications and it always will be,â he states. âMaking sure our platform is resilient, usable and mission critical in harsh environments while layering on this intelligence.â

Smart earpieces are the next frontier for the smart generation, we have all seen the earpiece that can translate instantly But that is just the start, as we can see from this article about this Xperia Ear wireless earpiece, it updates you from your phone when you put it in your ear. It wonât be long before we wonât need a smart phone everything will be in our ear.
Sony has revealed its âsmart personal assistantâ that include a bluetooth earpieceÂ will go on sale in November.
At the IFA show in Berlin today, the firm confirmedÂ it will launch this November âstarting in select markets,â although its price has still not been revealed.
The Xperia Ear wireless earpiece can update you with any missed calls or messages as soon as you slot it into your ear.
The firm also showed off aÂ Xperia Agent, a robot measuring just over one foot tall, that also works as a PA.
âIt will navigate you to where you want to go and make your life eye-free and hands-free,â said Sony Mobileâs President and boss, Hiroki Totoki of the âherâ earpiece when it was unveiled at the MWC show earlier in the year.
âIt is also powered by Sonyâs voice technology and will respond to a number of commands.â
The firm says the smart earpiece âis a next-generation wireless ear-piece that brings a new way of communicating, without compromising on enjoying the world around you.â
It reads users information such as your schedule, weather and the latest news to keep you up-to-date on the go.
Powered by Sonyâs voice technology, it responds to verbal commands, so you can ask it to make a call, perform an internet search, dictate a message or navigate to a certain location.
It connects to an Android smartphone via NFC or Bluetooth and talks to a host application, where you can customise settings, including the info you need when you first connect in the morning, touch commands and app notifications.
âIts lightweight and comfortable soft silicone ear-bud is built for continuous wear, with IPX2 water-protection and all-day battery life3,â Sony said.
Itâs available in Graphite Black and the innovative case doubles as a charger, so you can simply pop it in when you need to recharge.
It also unveiled the Xperia Eye, a wearable camera that acts as your personal sidekick, capturing everyday life moments with a 360 degree wide-angle lens.
Unveiled at Mobile World Congress (MWC) in Barcelona, the Xperia Eye can be attached to clothing or worn around the neck.
It forms part of a suite of connected gadgets designed to free people up from their phones.
Sony said the Xperia Eye is âa vision for a personalised assistantâ and joins three other smart gadgets that are connected to a Sony smartphone that acts as a hub, feeding information to them such as notifications.
These are Xperia Agent, Xperia Project and Xperia Ear.
Xperia Agent is a security camera-style device which acts as a home monitoring system, keeping an eye on whatâs going on around it and projecting notifications fed to it from a Sony smartphone onto surfaces around it.
âIt will provide you with useful information, communication assistance and home appliance controls,â Sony said.
Xperia Project projects an interactive interface onto any clear surface, meaning you can manipulate images, webpages and screens you would usually find on your smartphone, onto a hard surface.
Sony claims this projected image will respond to touch, voice and gestures just as someone would interact with your smartphone screen.
The Xperia Ear is a wireless earpiece that will update you with any missed calls or messages as soon as you slot it into your ear.
âIt will navigate you to where you want to go and make your life eye-free and hands-free,â said Sony Mobileâs President and boss, Hiroki Totoki.
âIt is also powered by Sonyâs voice technology and will respond to a number of commands.â
The wearable camera is the first time Sony has shrunk its image sensing and camera technology into such a small device.

Intel just announced its own virtual reality headset called Project Alloy, a VR competitor to theÂ Oculus Rift,HTC ViveÂ and the forthcomingÂ PlayStation VRÂ headsets. But what separates the Alloy from the pack is that itâs completely wireless (the wire above is for capturing video for the demo) and it should give you complete spatial awareness without all the dongles the Rift and Vive currently require.
It does this using two of Intelâs RealSense cameras to continuously map your environment. It can even map your hands.
Intel calls the idea âMerged Realityâ, essentially combining inputs from cameras around your environment into a virtual world. And Intel was able to pack everything â the processor, sensors and controllers â into one cord-free headset.
During Intelâs demo, however, the RealSense camera didnât seemÂ quiteÂ as fluid as youâd hope, especially if itâs your primary means of reacting to the digital world around you. Intel says that its hardware will be open source in the second half of 2017 (ugh), so the headset wonât be available anytime soon. Intel is also working with Microsoft so Alloy can run Windows Holographic, the softwareÂ which powers Hololens, according to Microsoftâs Terry Myerson. Microsoft says that Windows Holographic will also be released in an update for all Windows 10 PCs next year.

Anything with bone conducting technology, we will jump upon and love the hell out of! When we heard about Sunglasses that had speakers with bone conducting inside, to allow you to make calls and listen to music whilst on the move we thought what a great idea. This crowd-funder is looking to raise $50,000 but $1 million would be a good start. See more on this here.
One of the latest hot crowdfunding campaigns is for dark sunglasses called the Zungle Panther with bone-conduction technology that allows them to be usedÂ to listen to music and make phone calls. Jason Yang, Zungleâs 30-year-old CEO and co-founder, came up with the idea because he was annoyed with trying to wear an earpiece and sunglasses to listen to music while wakeboarding.
âWe all love extreme sports, and Jason is a huge fan of wakeboarding,â says Sean Bang, 30,Â ZungleâsÂ chief marketing officer and co-founder. âHeâll have sunglasses on, but eventually the earphone doesnât work with the sunglasses, and he felt that it was inconvenient and uncomfortable. So we decided to get rid of the inconvenience.â
With Zungleâs sunglasses, wearers can listen to music or make phone calls while skiing, biking or wakeboarding without worrying about an additional earpiece. Bone-conduction technology, in which you hear sound through vibrations to your skull rather than through your ears, isnât new. But the idea of putting it into relatively inexpensive consumer products, like sunglasses, has been gaining traction recently.
So after fiddling with the product for nearly a year, in June, the two friends, who had worked together at marketing firm Innocean Worldwide in South Korea, along with two other cofounders, Chris Hong and Injun Park,Â turned to KickstarterÂ with a stated goal of $50,000 for their high-tech sunglasses. As with many crowdfunding campaigns, that $50,000 number was a lowball one; Yang says âabout $1 millionâ was their actual goal. The Zungle Panther has a similar look to Oakleyâs shades, and retails for $150. Backers who chipped in $89 could get them in a choice of colors as a âreward.â âWhen we started, we didnât have enough money to create this product,â Bang says. âWe chose Kickstarter because we can target everyone around the globe.â
By the time the campaign ended, in mid-July, Zungle had raised more than $1.9 million, putting it among Kickstarterâs top 100 campaigns of all-time.

It is quite a common thing that musicians and artists that are exposed to loud noise, will eventually suffer from hearing damage. We have seen many artists suffer from this career threatening damage, the likes of Phil Collins, Eric Clapton and Ozzy Osbourne and the tinnitus that is effecting Chris Martin from Coldplay, this is a problem that many more will be affected by. This article from the BBC talks about Chris Goldscheider and his pursuit of damages over his hearing damage. Rightly or wrongly itâs an interesting tale.
A renowned viola player is suing the Royal Opera House for ruining his hearing and his career during rehearsals of Wagnerâs Die Walkure.
Chris Goldscheider claims his hearing was irreversibly damaged by brass instruments put immediately behind him.
The Musiciansâ Union says hearing damage is a major problem for musicians playing in orchestras.
The Royal Opera House denies it is responsible, but around a quarter of its players suffer hearing illnesses.
In court documents seen by the BBC, Goldscheider claims that in 2012 his hearing was “irreversibly damaged” during rehearsals of Richard Wagnerâs thunderous Die Walkure “from brass instruments placed immediately behind him” in the famous “pit” at the Royal Opera House.
The sound peaked at around 137 decibels, which is roughly the sound of a jet engine. The court documents say the noise “created an immediate and permanent traumatic threshold shift”.

Goldscheider says this amounts to “acoustic shock”, one effect of which is that the brain hugely amplifies ordinary sounds.
Music has been in most of Goldscheiderâs life: “For the last quarter of a century Iâve been a professional musician. Music was my income. It was my everything,” he says.
The son of a composer, from the age of 10 he spent in excess of six hours a day practising and rehearsing. He played the viola with the Royal Liverpool Philharmonic and BBC Symphony orchestras, before joining the prestigious Royal Opera House orchestra in 2002.
Career highlights have included performing live with the famous Three Tenors to 100,000 people at the Barcelona Camp Nou football stadium, and with Kylie Minogue on MTV. He has also recorded with artists including the band 10cc.
Goldscheider says the effects of the hearing damage have been devastating.
“Ordinary sounds like banging cups and glasses together is a very painful noise,” he says.
“My newborn daughter last year was crying so much I actually got noise-induced vertigo because of my injury and I ended up in bed for three weeks.”
The musician says he has lost the career he loved and his mental health has deteriorated as he struggles to cope with the impact and effects of his hearing problems.
Life has changed dramatically. To carry out ordinary every day tasks such as preparing food, Chris has to wear ear protectors. Especially upsetting is that he had been unable to listen to his 18-year-old son Ben – one of the countryâs outstanding young French horn players.
“Ben is a fantastic musician. I havenât been able to listen to him play or practice since my injury. Iâve missed him playing concerts and winning competitions. I canât even bear him practising in an upstairs room when I am downstairs in the house,” he says.

At the time of his injury, Goldscheider was provided with hearing protection capable of reducing the noise by up to 28 decibels, but his lawyers claim this was insufficient. They say he was not given enough training in how to use it and protect himself, and that the noise levels should not have been so dangerously high.
The Royal Opera House does not accept the rehearsal noise caused Goldscheiderâs injury, and denies that is responsible.
In a statement it told the BBC: “Mr Goldscheiderâs compensation claim against the Royal Opera House is a complex medico-legal issue, which has been going on for some time and is still under investigation.
“All sides are keen to reach a resolution. The matter is now the subject of legal proceedings, and in the circumstances it wouldnât be appropriate to comment any further at this stage.”
And according to Goldscheiderâs solicitor Chris Fry, part of the Royal Opera Houseâs defence breaks new legal ground.
“Essentially what is being said is that the beautiful artistic output justifies damaging the hearing of the musicians performing it,” he says.
“Thatâs never been tested by the courts. We donât think the court is likely to uphold that, in particular where itâs clear steps could be taken to maintain the beautiful sound and protect hearing at the same time.”
he Royal Opera House denies it is responsible for Chris Goldscheiderâs hearing issue
Hearing damage suffered by rock musicians is well documented. Years ago The Whoâs Pete Townsend went public about his hearing loss and famously said a doctor had told him: “Youâre not actually going deaf, but Iâd advise you to learn to lip read.”
Brian Johnson of AC/DC and Ozzy Osborne have also been affected. But what is far less well known is that it is a significant problem in the more sedate and sophisticated world of classical music.
There are around 100 players in the orchestra at the Royal Opera House. The BBC has learnt more than a quarter report occasional or mild hearing illness, and that in the 2013/14 season, there were seven cases of sickness absence related to noise problems and a total of 117 weeks of sick leave taken. Thatâs not music to anyoneâs ears.
Morris Stemp of the Musicians Union says there are many reasons for the hearing damage suffered by classical musicians.
“Conductors are allowed to ride roughshod over health and safety considerations,” he says. “They put players on the stage where they will be in harmâs way. And instruments are now louder than they ever were before because of the materials they are now made from.”
Add to that the increased number of live concerts prompted in part by the drop in income from CD sales, and there is a mix of elements that can put the hearing of orchestra players at serious risk.
Chris Goldscheiderâs case casts light on a little known or discussed problem, and will be watched closely by all those in the classical music world.

It is understood that ear moulded plugs are far more comfortable and effective than the mushroom plugs, but which ones are the best? The Custom fit or generic fit. This article runs over the positives and negatives of that question and comes to a conclusion, if your debating to get some moulded ear plugs or some from the shelf, you will want to read this first.
Over the past 20 years,Â In Ear MonitorsÂ (orÂ IEMs) have become a near-necessity for live performance.
In years prior, engineers would inevitably have to crank up a venueâs stage monitors loud enough for the musicians to hear themselves over the audience, over the sound coming from the stage, and over the main mix.
This would often lead to an arms race of ever-increasing stage volume, potentially causing feedback issues and compromises in clarity and quality for the live mix.
Custom in-ear monitors from JH Audio, one of the first commercial brands to make a name for itself in the IEM market.
With the advent of in-ear monitors, all this began to change.Â In the mid-1980s,Â EtymoticÂ developed the first-ever insert-styleÂ earphones, and soon after, a designer namedÂ Marty GarciaÂ began making one-off custom in-ears for rock stars like Todd Rundgren.
By 1995, Jerry Harvey, founder ofÂ Ultimate EarsandÂ JH Audio,Â brought some ofÂ the first commercially-available dual-driver IEMs to market. All of a sudden,Â everyday musicians had an option that allowed usÂ to save our hearing, get better monitor mixes, and dramatically reduce the chances of feedback onstage.
Today, IEMs are increasingly being considered useful tools for the studio as well. Their ability to prevent sound leakage can be of tremendous value in helping to control click and instrument bleed, and in saving musiciansâ hearing by allowing them to monitor at lower levels.
Some musicians and engineers, such as drummer Rich Pagano ofÂ The Fab Faux, will use IEMs to quickly check for phase when micâing up a drum kit, while others turn to IEMs as a kind of audio microscope, using them to help check for and remove extraneous low-level noise.
Any modern musician would be wise to consider adding in-ear monitors to their toolkit. But is it worth it to dish out the extra money on custom fit IEMs, instead of saving some money with the generic fit ones?
In testing a variety of in-ear monitors from brands like Westone, Ultimate Ears, Future Sonics, and even Skullcandy (that last of which is not recommended for professional use), I have found that there are cases in which generic fit earphones may work better than their custom counterparts. Making the right decision for your needs comes down to considering the following four factors:
Ultimate Ears custom fit in-ear monitors.
Custom fit IEMs tend to cost more than generic fit ones, as it takes more time and effort for the manufacturer to craft a product designed specifically for the unique anatomy of your ear.
Getting custom IEMs made also requires that you go to an audiologist to make a mold of your ear canal that the IEM company can then use to make your monitors fit as well as possible.
Take note of both of these costs, which can range from $100-$200 or more for a fitting from an audiologist, and $299-$1499 or more for the custom monitors to be made.
2)Â Comfort & Seal
Custom fit IEMs areÂ custom, so they should feel really comfortable, right? Â Well, yes and no.
In my experience, custom fit IEMs can feel a little tight in the ear canal compared to generics, especially at first. Hearing so little acoustic feedback from your performance can also take some getting used to, and the tight seal of custom fit in-ears can feel particularly awkward when signing.
Because of this, my looser-fittingÂ Westone 3Â generic IEMs actually feel more comfortable to me on vocal duties, so I often find myself using them over my custom fitÂ Future SonicsÂ when I step up to the mic.
Matt Bellamy from MuseÂ (recently featured inÂ Get THAT Guitar Tone) has been seen using both customUltimate Ears UE-11s and generic-fitÂ Westone UM2s when on tour, and my guess is that he has similar reasons.
Though the tight fit of custom IEMs and lack of acoustic feedback from your performance can be a challenge, itâs worth noting that generic foam-tip IEMs also provide their own tradeoffs: The looser fit of generics can sometimes create a bit of a tingling or âticklingâ feeling in your ear when playing at higher volumes, so it may be useful to have a pair of each and go with what feels best depending on the date and venue.
Silicone-based Encore Studio custom IEMs from ACS.
Another option here is the custom fit brandACS, which makes its IEMs out of soft silicone shells.
This softer silicone-based design is meant to offer both better comfort and a tighter fit than the hard acrylic shells used by brands like Westone and Ultimate Ears.
Though these silicone monitors sell for a premium price of $400-$1,200 and up, they may help bridge the gap between the tight seal of custom acrylics and the looser and easier fit of foam-tipped generic IEMs.
3)Â Hearing Protection
In addition to cutting down on sound leakage to help improve sound quality and reduce feedback, another primary benefit of IEMs is that they can offer considerable hearing protection by helping to block out exterior noise, allowing you to monitor at lower levels.
Some of the best custom fit brands likeÂ JH AudioÂ andÂ Ultimate EarsÂ offer NRR ratings of 26dB in reduction, and some of the better generic brands advertise comparable results as well. (Though your results with generics may vary depending on the fit and seal in your ear.)
In the long term, reducing the levels youâre regularly exposed toâeven by a few extra decibelsâcould mean the difference between a long and illustrious career as a âgolden-earedâ audio engineer and potentialtinnitusÂ and irreversible hearing loss.
Also worth checking out is theÂ REV33Â system, which can be added on to yourÂ your in-ear-monitoring system to help reduce distortion and ear strain. Many live musicians, includingÂ Phil XÂ and Steve Salas swear by the system. According to the company:
âAll in-ear monitors and headphones generate damaging, unwanted noise and distortion that forces the ear to shut down and compress for protection. The REV33 reduces the symptoms of tinnitus, ear-ringing, ear-fatigue, buzzing and dampened hearing by preventing in-ear monitors and headphones from producing this unwanted noise and distortion.â
4)Â WaitingÂ and TimeÂ Considerations
After getting my first pair of IEMâs made, I found that the right ear monitor turned out well, but I was not getting a proper seal in the left ear at first. This made the monitors essentially useless for my live sound needs at the time, and so I had to send them back for some tweaking.
When I got them back a couple of weeks later, the seal still wasnât great, so I had to send them back once again for further modification, and visit my audiologist a second time to take another impression of my ear canal to send in.
Getting the perfect fit turned out to be quite a time-consuming process (as well as an expensive one) so unless youâre on the hunt for a long-term solution with as much acoustic isolation as humanly possible, you might satisfice with generic IEMs, or keep some around as an alternate option.
In that case, I would recommend the generic in-ears from Ultimate Ears, Shure, or Westone.
Ultimate Earsâ generic fit UE900 model sports 4 drivers for $400.
TheÂ Ultimate Ears UE900âs are a great sounding 4-driver IEM that only costs $399, while the $99Â Shure SE215Â single-driver IEMs advertise an astonishing 37dB of noise reduction (more than most custom IEMs) at a great price.
My own triple-driver Westone 3âs (since replaced by theÂ W30 model) are the most comfortable in ear monitors I own right now, and they isolate a lot more noise than most thanks to their foam-tip construction.
Compared to custom in-ears, any of these model can potentially save you time and money, or work as a welcome supplement for those times when the tight fit of custom in-ears feels irksome.
I hope my experiences here help you make the right decision when you go to buy your own IEMs. In short, I found that less-expensive generic foam-tipped IEMs worked better for me in many situations, and the savings enabled me to spend my money on better drivers with a fuller sound.
If youâve used IEMâs in the past, let us know in the comments below whether you prefer custom fits or generic fit ones, and why.

Technology is improving each and every day, but these advancements have left many of us tightly trapped in the luxuries and comforts, imposing many side effects on our overall health. One such modern advancement in technology that’s affecting our health is the use of headphones. Today, many people use headphones without knowing the kind of negative health issues the devices can cause.
Well, although headphones are an ergonomic, convenient and quite useful hands free accessories, there are various health risks that are associated with their use. Experts believe that prolonged use of headphones can cause great damage to the ears. In addition, headphones cause ear infections, which contributes to hearing loss. Well, some of the risks that are associated with headphones have more to do with their use and maintenance, than with the headphones mechanics.
Ear infections are much more likely to occur amongst the headphone users who wear the devices for extended periods of time, and also amongst those who don’t take good care of their headphones. For example, headphone ear cushions need to be replaced every 2-3 months, and should be treated regularly with the right cleaning agent so as to avoid accumulation of germs and bacteria. Prolonged headphone use also causes aural hygiene issues, hearing loss along with ear canal infections. Recent scientific studies have revealed that wearing headphones for extended periods of time usually increase the humidity and the temperatures inside the ear canals, thereby increasing one’s susceptibility to ear infections. This shows that headphones cause ear infections.
Sharing of headphones is another way headphones cause ear infections. It is quite common for people to share their headphones with others. Sharing headphones with others is not a good idea since the bacteria from other people’s ears will travel to your very own ears and this will cause ear infections. Therefore, the next time you think of sharing your headphones, think again. Do not share your headphones with anyone, not even your friends or family.
Listening to music together is another way headphones cause ear infections. As romantic as it may seem, there are dire repercussions to sharing headphones. In the process of enjoying music together, you will end up transferring somebody elseâs bacteria to your ears; this can lead to ear infections. Make sure you sanitize your headphones by thoroughly cleaning them with a clean tissue paper before plugging them in.
Apart from the germs and bacteria you get from borrowing or/and sharing headphones, you can also get germs and bacteria from not changing your very own headphone sponges. It’s recommended you change the rubber or sponge cover of your headphones every 2-3 months mainly because they tend to get covered with germs and bacteria over time.
Some other ways you can avoid ear infections caused by headphones is by always keeping your headphones clean, regularly replacing the old headphones and ear pads, avoiding sharing headphones or using the public headphones, and not sharing earbuds. Also, if your headphones have a sponge or a rubber cover, make sure you change them every 2 months. Finally, remember to give your ears some rest once every 15 minutes, and do not play the music way too loud, for this might contribute to hearing loss.

Many business and factories are very well aware of their legal obligations when it comes to occupational deafness, and here in the UK we have the Control of Noise at Work Regulations 2006. Many of the headsets that are listed on Headsetonline.co.uk are designed exactly for these types of industries, with their experience they are a leader in radio headsets and hearing protection equipment. But as the article below explains the protection has to personalised to everyone, so as to make sure that the individual is catered for and protected adequately. The original source of this article can be found here.
Hearing loss is preventable. Why, then, is it still so common? NIOSH notes that occupational hearing loss is one of the most common work-related illnesses in the United States. And according to OSHA, approximately 30 million people in the United States are exposed to hazardous noise on the job.
âNoise-induced hearing loss is generally a gradual and painless process, so many workers donât consider it a hazard â¦ until itâs too late,â said Katie Mielcarek, marketing manager for Cleveland-based Gateway Safety Inc. Mielcarek went on to say that workers donât wear hearing protection for many reasons, including discomfort, poor fit and problems with compliance monitoring and trouble inserting earplugs.
Here, industry insiders discuss whatâs new and offer advice on hearing protection.
âElectronic muffs contain the latest technology designed to protect against environments with impulse noises,â said Eric Moreno, market manager for Cranberry Township, PA-based MSA. âThe technology amplifies weak sounds while compressing dangerous noises to a predetermined safe level of 82 dB or lower.â Moreno said this allows face-to-face communication and lets workers hear important sounds, such as warning signals.
Gary Klee, product manager for above-the-neck products at Latham, NY-based Protective Industrial Products Inc., pointed to a âlevel-dependent systemâ available with electronic earmuffs. This system has microphones in both ear cups to help limit sounds reproduced through the internal speakers to a safe level, which âallows communication with others while remaining protected against impulsive or hazardous noise,â Klee said.
Ricardo Allamelou, COO for Miami Lakes, FL-based Cotral Lab Inc., said providing every worker with the exact same type of hearing protection doesnât make sense. âThe protection has to be personalized since overprotection is as dangerous as no protection at all,â he said.
According to Moreno, âOverprotecting can actually increase the danger to a personâs life because this can hinder their ability to hear relevant noises such as warning signals, moving vehicles, other workers, etc.â To reduce the chance of overprotecting, Moreno recommends thoroughly understanding the level of noise in every area of the workplace to determine what level of protection each area needs.
Additionally, be sure your hearing protection is independently, third-party tested to verify noise reduction ratings, Mielcarek said. âThis helps communicate quality in an industry where many manufacturers simply mark their products with a standard or a rating, without the testing to back it up.â

This is an interesting review of a paid article, depicting which isÂ represent by a drawing, painting, or other art form can be used as a form of communications, the type of depicting is described here in many different forms and that is where we will allow the article to take up the story.
When we think of language, we usually think of words, phrases, and sentences–strings of abstract symbols. In research over the past 50 years, cognitive and social scientists have developed extensive accounts of how people communicate with these symbols. But when people are face to face, they also communicate with actions that depict people, objects, and events. They create these depictions with their hands, arms, head, face, voice, and entire body, sometimes with other props but often without.
In an article recently published Online First in Psychological Review, Herbert Clark argues that spontaneous depictions like these are missing from general accounts of how people communicate, and that is a major failing. Why? Because depicting is common in everyday conversation and depicting things is fundamentally different from describing things. Also, a great many utterances are “composites” of depicting and describing.
Clark’s point is nicely illustrated in a report, from the New Yorker, of Hollywood director WG telling correspondent TF about having to stop filming in New York because of some falcons nesting on the ledge of a building:
“In L.A., they would have–” He leveled a finger at some imaginary nestlings and made a gun-cocking sound.
As Clark notes, WG could easily have described the scene with the phrase “shot those falcons.” What he did instead was depict the scene with his finger, hand, head, eyes, and voice. The result included a depiction (leveling a finger and making a gun-cocking sound) in place of the phrase “shot those falcons.” Traditional accounts are unable to handle composites like this.
What is depicting? In the theory developed in this paper, to depict something is to stage a scene. When WG leveled his finger at the imaginary falcons, he enacted a shooter in L.A. aiming a rifle at some falcons. And he did that so that his listener could imagine the scene vividly. Depicting is much the same as putting on a play in the theater or engaging in make-believe play.
Depicting, according to Clark, is largely complementary to describing. To begin with, many ideas that are impossible to put into words are easy to depict. Tennis coaches don’t describe how to hold a racket or do a backhand return. They demonstrate it, and in living detail. Music teachers often correct their students by playing or singing what the students should have played or sung. And although it takes years for children to tell coherent stories, they have little trouble depicting stories in make-believe play. They readily enact Cookie Monster, Mother, cops and robbers–and play out what they do.
Depicting is also effective for emotion, excitement, and empathy. In telling stories and passing on gossip, people not only describe, but dramatize what the protagonists said and did, often with passion and attitude. And in apologizing, people not only say “Sorry” but add facial gestures that depict their regret.
The idea, then, is that depicting is a method of communication. Without depictions, talk would be flat, lifeless, and sometimes even impossible.

We all know how important radio communications are, and Motorola Solutions have captured a massive coup by providing the radios for protecting the Chinese forests, a feather in the cap for Motorola because Hytera, their biggest competitor at the moment, originating from china, interesting! We found this article on this website.
Motorola Solutions (NYSE:MSI) with its channel partner Beijing Dyne Rcomm Technology are helping to keep Chinaâs Hunan forestry region safe with aÂ MOTOTRBO digital radio system that increases safety and security for employees while helping them to work more efficiently.
Chinaâs Hunan province is rich in flora and fauna resources that are essential to the regionâs economy. However, these vast areas which make up around 60 percent of the provinceâs total surface area can be risky places to work for forest rangers. Forest workers depend on reliable communications to be aware of potential bushfire risks and other emergencies.
The innovative radio system integrates MOTOTRBO digital two-way radios and repeaters, a dispatch console for centralised control and monitoring of the network at all times and Motorola Solutionsâ IP Site Connect digital solution to extend radio network coverage over the internet throughout the counties and cities.
âRangers depend on access to clear and reliable communications. They need to stay constantly connected to their colleagues working in control rooms who have visibility of the entire operation and can help to keep them safe at all times,â said Michael Jiang, China President and Country Manager, Motorola Solutions.
âItâs absolutely essential for forest rangers to know where their co-workers and resources are at all times, especially in times of emergency.
âHunanâs new radio network provides extensive coverage throughout the region, enabling rangers working across a wide geographic area to report the very first signs of fire so that resources can be deployed quickly and effectively to protect lives and natural resources,â Mr Jiang said.
Hunanâs integrated system connects the surrounding cities and counties through clear voice communications enhanced with noise cancelling features that perform reliably in the nosiest environments. This system also supports data transfer across the radio network, using GPS to pinpoint the location of nearby team members and resources in emergency situations, while text messages and automatic alerts can be sent between the provinceâs central control room and radio users in the field.
Motorola Solutions has now deployed more than 5,000 radios to major forestry projects across greater China at locations including the Inner Mongolia, Hebei, Liaoning, Sichuan and Guangdong provinces.

Motorola has completed itsÂ acquisition of Airwave, the former provider of the mobile communications network for UK emergency services.
The acquisition was completed on a debt-free basis with a net cash payment of around Â£700 million, with a deferred cash payment of Â£64 million to be made in November 2018.
Motorola expects the acquisition to immediately contribute to non-GAAP earnings and free cash flow.
Airwave is headquartered in Berkshire, England, and employs roughly 600 people. It is owned by a fund of Australia’s Macquarie Group.
In late 2015, Airwave filed a legal challenge to the Home Office after EE became the preferred supplier to provide a 4G network to the UK emergency services.Â MotorolaÂ is the preferred bidder for user services to the emergency services.
Airwave complained about the procurement process and the inability of the cellular network to handle the traffic. Currently these services are provided through Airwave’s own terrestrial trunked radio, or Tetra network, which will cease to be a component of police radios.
The decision to move from Tetra has been criticised by some, including members of the Tetra + Critical Communications Association.
Advocates of moving to 4G cite alleged failures of the network during the 2011 riots.
“The acquisition of Airwave enables us to significantly grow our managed and support services business and reflects our commitment to the public safety users in Great Britain,” said Greg Brown, chairman and CEO of Motorola Solutions.
“The combination of our years of experience as a trusted global leader in mission-critical communications and Airwave’s proven service delivery platform will provide Great Britain with innovative emergency services technology that enhances public safety today and into the future.”
This has been in the news for a while and it is a really smart move by Motorola, they have purchased the company that run all the communications for all the UKâs emergency services (tetra network) and manage all of the infrastructure along with that, so with the up-coming contract renewal and many of the phone companies sniffing around looking to capitalise, Motorola have shored up their position with this acquisition. We found this article here, where you can find a lot more on the story throughout the site.

We will see a huge change in the way we access the the internet in the future when 5G is here, at speeds that only big businesses and high level internet companies see at the moment, we will have this to hand on our smart phones and tablets. When 5G is hundreds of times faster than any of the UK’s broadbands, households will be looking to the mobile phone companies to supply their home broadband.
A 5G future is no longer a distant one, but an upcoming reality. High quality videos of more than 10Mbps can be served simultaneously to 100 users even in a train running at up to 500km/h. People can experience data rates that are 100 times faster than currently available technologies.
The Electronics and Telecommunications Research Institute (ETRI) of Korea will hold a “5G technology demonstration” on the 18th December, 2015. It will demonstrate future SNS (social network service) and several 5G core technologies such as “millimeter wave”, “Mobile Hot-spot Network”, “in-band full duplex” and so on.
5G is the next generation wireless technology that would provide even faster data rates, even lower delays, and even more devices connected than 4G. Accordingly, distinct and differentiated applications are expected in 5G.
ETRI’s “future SNS” is a kind of trial service model to apply 5G technologies that provides dynamic user-centric connection to neighboring people, things and spaces. It is characterized by instant content-sharing between users, communication with neighboring things, and Giga-bps(Gbps)-grade video applications in vehicles.
5G core technologies demonstrated by ETRI include the following:
— MHN (Mobile Hot-spot Network) is a mobile backhaul technology that provides high-speed Internet access of Gbps in vehicles at speeds of up to 500 km/h (e.g. KTX in Korea). Almost 100 passengers can watch videos of high quality simultaneously.
— ZING is a near-field communication technology that enables mass data to be transmitted with 3.5 Gbps data rate between neighboring devices within the radius of 10cm.
— Single-RF-Chain compact MIMO technology enables a single antenna to simulate the effect of multiple antenna. It can reduce antenna volume and cancel inter-antenna interference in a multi-antenna system.
— Millimeter wave (mmWave) beam switching technology provides fast switching of radio beams to mobile users, and therefore allows seamless Gbps-grade service in mobile environments.
— Mobile Edge Platform (MEP) is a mobile edge cloud server on vehicles that enables passengers to enjoy customized Gbps-grade content and connects them with neighbors, things and spaces. It provides user-centric services.
— In-band Full Duplex technology can transmit and receive signals simultaneously over the same frequency band. It can increase spectral efficiency by up to two times.
— Small cell SW technology is designed for AP(Access Point)-sized small cell base stations that can reduce communication dead zones and improve data rates per user in a hot-spot area.
“With this demonstration event, we are officially introducing our R&D results on 5G. We will continue to lead the development of 5G technologies. Also, we are trying to develop commercialization technologies needed by businesses, and to construct a 5G ecosystem.” said Dr. Hyun Kyu Chung, vice president of ETRI Communication & Internet Lab.
In January, 2016, ETRI will demonstrate Giga internet service and future SNS in a Seoul subway train installed with MHN and ZING kiosks. ETRI will also introduce hand-over technology on a millimeter wave mobile communication system and 5G radio access technology that satisfies 1 millisecond radio latency.
Established in 1976, ETRI is a non-profit Korean government-funded research organization that has been at the forefront of technological excellence for about 40 years. In the 1980s, ETRI developed TDX (Time Division Exchange) and 4M DRAM. In the 1990s, ETRI commercialized CDMA (Code Division Multiple Access) for the first time in the world. In the 2000s, ETRI developed Terrestrial DMB, WiBro, and LTE-A, which became the foundation of mobile communications.
Recently, as a global ICT leader, ETRI has been advancing communication and convergence by developing Ship Area Network technology, Genie Talk (world class portable automatic interpretation; Korean-English/Japanese/Chinese), and automated valet parking technology. As of 2015, ETRI has about 2,000 employees where about 1,800 of them are researchers.

Bluetooth technology has been designed for many different purposes and situations. Consequently, when people want to buy a bluetooth ear piece for a specific situation, there are some things that they will need to consider. Specifically, based on their specific situation and circumstances, they will need to review the best style of bluetooth earpiece that is available on the market today. Since there are different styles that have been made for for one or more reasons, it’s important for each individual to do their research to see which style can accommodate their needs. It is also important to note that the kind the person purchases must be comfortable so that they can wear them for an extended period of time and they fit the devices that they will be used for. Listed below are three of the bluetooth styles thatâs currently offered by manufactures all over the United States and abroad.
Bluetooth ear pieces for Mobile Phones
Most people take their mobile phones wherever they go. To work, school, church, parties and all kinds of other events that they may attend. Because these phones have become commonplace in many environments, people have a need to handle them and talk to others when their hands are free. This is also a great reason for individuals who work in certain settings to make sure that they are buying the right style that will best fit their needs.
One specific style that some people may choose is the ear cradle style of headphone. In fact, this kind of bluetooth earpiece is idea for people who want to spend their time working out and performing all kinds of other extracurricular activities. People are also encouraged to buy this kind of style because they may be driving when they receive a telephone call from a family member. Or, they may be working at the job typing a memo or walking around taking care of wide hosts of other kinds of activities that are not conducive to holding a mobile phone by hand to the ear. Whatever the situation, this style of bluetooth earpiece technology is great for many different situations and purposes.
Bluetooth ear pieces and Headsets for Music Lovers
In addition to the cradle style for mobile phones, people should also review other styles as well. One specific style that is also functional in many different settings is the DJ over the head headphones. This style has been designed for the serious music lovers, especially those who can appreciate making distinctions in sounds and beats that come from specific musical instruments like the bass, violin, trumpet and other popular instruments. For those who like and prefer this kind, they will also find that this is one of the best styles for keeping out outside noises that normally interfere with a personâs overall entertainment experience. Also, because they are wireless, they are great for people who like to stay mobile during the day instead of remaining in a sedentary position.
Bluetooth Ear Pieces for IPODs
In some situations, people may want to use bluetooth technology with their IPODs. Therefore, they should consider buying an additional popular style bluetooth earpiece technology. This style is known to be very popular, specifically because it is similar to an actual earbud. An ear bud is also another excellent choice for people who want to remain both active and hassle free. Though this is a great choice for people who like to remain mobile in a wide variety of different situations, one of its main draw backs is that they tend to fall out of the individuals ear. Which means, they can also be lost since it lacks additional support to keep them stabilized inside the ear.

This is an interesting review of a study of how effective ear plugs are in the workplace. We take for granted that people working in loud factories wear protective hearing, but many of the clubs, pubs, concerts and festivals that have as equal levels of sound. As they say below, it isnât mandatory to wear ear plugs in such environments, which defies common sense and possibly causes more damage than we understand. Here you can find the original source of the review.
A review of the literature turned up only two high quality studies that looked at whether wearing earplugs to music venues will prevent hearing loss and tinnitus directly afterward.
Dr. Wilko Grolman and colleagues at University Medical Center Utrecht in The Netherlands searched for published studies containing the keywords âmusicâ and âearplugsâ and screened 228 resulting papers. All but four were not eligible for inclusion in the review and only two were highly relevant and did not have a highÂ riskÂ of bias, in the reviewersâ estimation.
Two studies simply examined people who chose on their own to wear or not wear earplugs, while two randomized controlled trials tested what happened when participants were assigned to wear earplugs or not.
Two studies reported on hearing loss and tinnitus while one only reported hearing loss.
The two best studies were different enough that the researchers couldnât combine their dataÂ and analyze the results, the reviewers wrote. Both included 29 concert attendees and performed audiometry before and after the concerts. In one study, participants were allowed to choose whether or not they wore earplugs, and only three chose to wear them.
âFrankly, with such a small comparator group between three subjects and the others, it would be hard to assess validity of plugs or not,â said Dr. Jennifer Derebery, president of the Los Angeles Society of Otolaryngology and lead author of the first study.
âWe had trained them all in proper insertion, and encouraged but not required wearing them,â Derebery told Reuters Health by email.
In the other study, 15 participants were assigned to the earplug group.
In general, wearing earplugs did reduce hearing loss directly after the concerts, but did not eliminate it completely, as reported online March 3 in JAMA Otolaryngology-Head and Neck Surgery.
âEar plugs are effective in preventing hearing loss when they are used both correctly and consistently,â said Colleen G. Le Prell, the Emilie and Phil Schepps Professor of Hearing Science at the University of Texas at Dallas, who was not involved in the review.
âThis systematic review highlights the very limited data on prevention of recreational music-induced hearing loss using earplugs,â Le Prell told Reuters Health by email.
âAt younger ages, loud toys, firecrackers, loud video games, personal stereos or personal music players, lawnmowers or leaf blowers, sporting events or air shows, or other non-music events might be more likely noisy activities than music venue attendance,â Le Prell said. âA significant number of youth are also involved in target shooting activities, which children can get involved with through Boy Scouts or other organizations.â
For teens and young adults, repeat exposures to amplified music at clubs, concerts, festivals, or other related events may damage the inner ear and result in hearing loss, she said.
âMost concerts are both loud enough, and long enough, that they are likely to exceed the total daily exposure allowed by workplace safety regulations,â she said. âSound exposure also commonly occurs via loud music delivered via personal listening devices, at sporting or other recreational events, and at jobs that involve lawn-mowing, use of power tools, or construction services.â
For workplace noise exposure, âwe are not doing a very good job achieving correct and consistent use of hearing protection devices (HPD), including both ear plugs and ear muffs,â she said.
âIn the United States, it is relatively uncommon for music venues to provide ear plugs at no charge,â Le Prell said. Even if they were provided, people may need to be educated in why using them is important and in how to use them correctly, she said.
âAs a neurotologist, it really is upsetting to see these kids coming in younger and younger with a completely preventable hearing loss,â Derebery said.

We all know that mission critical communications are vital 24 hours a day and as this article shows that even a tiny lapse in communications can lead to chaos. Even the U.S government canât keep their radio communications up-to-date on one of the most watched borders in the world, as we can see from the article below.
Put yourself in the shoes of a U.S. Border Patrol Agent. You are patrolling the U.S.-Mexico border, driving through desolate terrain, and in the distance, you spot movement. You head toward a deep ravine and step out of your vehicle when a shot rings out and you hear the zip of a bullet speeding past your head. With training and instinct, you dive for cover and draw your weapon, reaching for your handheld radio.
And the radio doesnât work.
Thereâs no one to call, because you are in one of the many areas of the southern U.S. border that has no radio coverage. Out there in the ravine is a drug cartel ârip crew,â heavily armed and firing on your position, bullets punching into your vehicle until smoke is rising from the hood. If they come closer, you are outnumbered. If they flee, your vehicle is disabled, and they will disappear into the vast emptiness along the southern border, where they will likely fire on one of your fellow agents, should they encounter them.
That is the state of communications along many of the areas on the U.S.-Mexico border. When the U.S. Border Patrol needs it the most, they cannot communicate with anyone. With rising threats and political propositions, U.S. border security has again risen to the top of the public consciousness. There are calls for more border patrol officers and stronger fencing, for aerial and ground based vehicles and other technology. But the lifeblood of the border security apparatus is communication, and in some areas, communication is not possible.
âIf there is one thing in securing Americaâs borders that hasnât changed since September 11, 2001, itâs the inability to resolve the communications lapses and gaps along the border,â said Ron Colburn, the former National Deputy Chief of the U.S. Border Patrol. âHere we are almost 15 years into this, and we still have not addressed this problem.â
One reason 343 New York City firefighters died when the World Trade Center buildings collapsed was that their radios could not communicate with the emergency responders outside the buildings, who were warning the structures were about to come down. The recommendations of the 9/11 Commission cited the need to create interoperable tools that allow first responders and law enforcement to communicate in the most unforgiving of environments.
And there are few environments less forgiving than the nearly 2000-miles of the U.S.-Mexico border.
Recognizing this, the Department of Homeland Security (DHS) launched a massive project to improve the communications capacity of officers along the U.S. border. It failed. In March last year, the U.S. Government Accountability Office (GAO) reported that $945 million in taxpayer funding used to build radio towers and upgrade radio equipment has yielded little benefit and in some cases does not work as well as what Border Patrol agents were using before. The effort cost too much and was taking too long.
Colburn said that the state of communications today means U.S. Border Patrol cannot call for support in some areas. They cannot feed information from the field into the intelligence food chain, and they cannot receive images from manned or unmanned vehicles to know whether they are walking into an ambush or encountering a group of friendly forces.
Likewise, Border Patrol agents cannot communicate easily with other law enforcement agencies (like a local Sheriffâs office), nor can those law enforcement agencies run on-site biometric checks (e.g., fingerprints) of individuals they suspect may have recently crossed into the United States illegally.
âI see it in the eyes and hear it in the voices of the men and women of the Border Patrol,â said Colburn. âThey understand the mission and they want to accomplish it, but they feel like they have been abandoned.â
Answering the Unanswered Question
Most Americans own a smartphone, which is a powerful piece of technology. Experts say itâs hard to understand how, in this age of technological innovation and advancement, the United States is not arming its frontline officers with the very basic capacity to talk to one another.
Part of the challenge is that we have not brought new solutions to this long-standing problem.
To advance the effort, the Border Commerce and Security Council (of which I am Chairman and CEO) helped bring multiple stakeholders to the table in December last year in Cochise County, Arizona, to see if an innovative application of several integrated technologies could solve these communications challenges. It was a Proof of Concept test that included the U.S. Border Patrol, the Cochise County Sheriffâs Office and a group of businesses with tools that can address a range of communications and intelligence challenges. What was tested is called the Field Information Support Tool (FIST).
FIST started in 2006 as basic research at the Naval Postgraduate School (NPS). NPS Information Sciences Research Associate James Ehlert said in 2010 that the goal was to create âan easy-to-use, inexpensive hand-held solution to achieving communications interoperability and a common physical and human terrain operating picture for both on-the-ground field collectors and tactical decision makers.â
The research question was, how can we use modern technology to allow officers in the field to talk to one another and to their superiors while also collecting and then acting on real-time intelligence?
âThe intelligence aspect is that the local and federal law enforcement officers need to look at things from a risk-management perspective,â said Brian Conroy, Business Strategy and Strategic Development Manager at NOVA Corporation, which works with Kestrel Technology Group, the company that has produced the FIST system. âThey need to find the high-risk areas [along the border], and if you have a tool that collects data and runs algorithms against it, you can conduct risk assessment and trend analyses. Human intelligence contributes to a holistic common operating picture.â
This is what the FIST system achieves, and itâs what was seen during the proof of concept test. In general terms, FIST uses off-the-shelf communications tools (like an Android device) to gather intelligence from officers on the front lines. With these tools, officers feed information into a larger database compiled from a variety of sources (including other officers) that informs strategic and tactical decision making. This is then passed back to the people working along the border.
The need for this kind of tool is obvious, but it has only been recently that the right technologies and software were put together in a way that makes it possible.
Moving to the Market
Over the last year, there has been a push to transition FIST into the marketplace. Research transition is tough, as DHS has found in many cases over the years. Unlike other agencies and components, such as the military branches, the homeland security and law enforcement marketplace is heavily fragmented and with limited resources. It makes it difficult to take good, workable ideas from prototype to production. As big of a challenge as creating an innovative piece of technology is finding a way to produce it in line with operational and funding realities. A local Sheriffâs office, for example, does not have an endless amount of funding and time to bring in expensive technologies and then train deputies to use them. For that matter, neither does the U.S. Border Patrol.
Whatâs needed is a simpler, cheaper solution, and based on the proof of concept testing, FIST appears to be that solution.
âItâs ideal for smaller law enforcement agencies because it can unify operations and reporting and scale capability, creating a force multiplier,â said Ivan Cardenas, technical director of the Kestrel Technology Group, which is helping to bring FIST to market. âIt is a sophisticated system, but it is easier to use than the complexity suggests.â
There are a few moving parts here. There are applications that allow off-the-shelf technologies to record and report intelligence, such as the location of a breach in the border fence or evidence of people moving through the rugged terrain. There are existing law enforcement and Border Patrol network capabilities (or cloud-based tools) that store that information. The secret sauce, however, is the complex digital architecture that allows real-time control and fusion of multiple information sources in a way that supports the mission. This is the one thing that has been missing from the border communications and intelligence efforts, and itâs why DHS has struggled to address the challenges to this point. The innovation is in the complexity, and FIST makes it simple.
Of course, that complex innovation is for naught if the agents in the field cannot transmit and receive intelligence. Enter SiRRAN Communications, another stakeholder at the proof of concept test in Arizona.
âWe often forget that without network access, weâre blind,â said SiRRANâs Director of Sales Mark Briggs. âOur technology brings that cell network to anywhere that it is needed.â
Briggs describes this technology as a portable, battery powered cell networkâa network in a box. It creates a local, closed network that any agent within range can access to communicate and record intelligence. The unit provides local communication in areas where there is no coverage, and if there is no way to access the communications grid, it captures intelligence and transmits it to the larger repository as soon as it finds a signal.
The lesson here is not just that FIST is a workable system to satisfy the mission needs of Americaâs border security and law enforcement professionals. Itâs also that the answer to the communications challenges along the border will not come in the form of $1 billion worth of cell towers built under DHS management. If it were, we would have solved this problem by now. The fact that we have not reveals that the ultimate solution is necessarily complex and multifaceted while also being easy to use and in-line with realistic operating budgets.
Perhaps the most important lesson, however, is that there are real tools that our Border Patrol and law enforcement officers could be using. Right now there are thousands of men and women on the border, and until we give them the tools they need to do their job, it will make border security and the safety of our frontline heroes difficult to sustain.
