We found this article and couldn’t not post this to our blog, it shows how hearing damage is on the upsurge. With cases of hearing loss growing every year, hearing amplifiers and hearing aids sales have consistently increased. There doesn’t seems to be an answer to this rise but as technology improves, answers can come that way.

Hearing loss can occurs when inner ear or nerve is damaged, which may be caused due to diseases, aging, loud noise, and medications. Hearing amplifier is a small part of hearing aid which makes the sound louder. Hearing amplifiers increase the power of signals and then send them to the ear through speakers.

Hearing aid is useful in improving the hearing and speech of patients. An otolaryngologist investigates the cause of the hearing loss. An audiologist is a hearing health professional who identifies and measures hearing loss and will perform a hearing test to assess the type and degree of hearing loss.

Increase in number of hearing impairment cases coupled with rising costs of hearing aids are expected to drive the growth of the global hearing amplifiers market during the forecast period. Majority of the consumers use hearing amplifiers or personal sound amplification products (PSAPs) as they are considered cheaper alternatives of hearing aids. Hearing amplifiers or PSAPs, are designed to amplify sounds in any recreational environment and are exempt from the Food and Drug Administration (FDA). Hearing amplifiers are sold directly to consumers as electronic devices without the requirement of a physician prescription.

According to National Institute on Deafness and other Communication Disorders (NIDCD), approximately 324,200 cochlear implants have been implanted worldwide. About 15 percent of Americans (26 million people) between the ages of 20 and 69 have high frequency hearing loss due to exposure to noise at work or during leisure activities. Major driving factors for the growth of the global hearing amplifiers such as an increase in the number of prevalence of hearing impairment patients in old and young population, increasing investment in research and development in ENT field among others.

Based on styles or design types of hearing aid products the global market of hearing amplifiers can be segmented as follows:

-Behind-the-ear (BTE)

-Mini BTE

-In-the-ear (ITE)

-In-the-canal (ITC)

Based on function the global hearing amplifiers market can be segmented as follows:

-Analog hearing aids

-Digital hearing aids

Based on distribution channels the global hearing amplifiers market can be segmented as follows:

-Hospital Pharmacies

-Online Pharmacies

-Independent Pharmacies and Drug stores

Hearing amplifiers market is segmented into five major regions: North America, Europe, Latin America, Asia Pacific, and Middle East & Africa. In 2015, North America lead the global market of hearing amplifiers followed by the Europe in terms of revenue. According to statistics compiled by the National Institute on Deafness and Other Communication Disorders (NIDCD), 37.5 million adults aged 18 and older in America report some form of hearing loss.

According to the National Institute on Deafness and Other Communication Disorders (NIDCD), 28.8 million U.S. adults could benefit from using hearing aids and more than 90 percent of deaf children are born to parents suffering from some kind of hearing disorder. Globally, the hearing amplifiers market is expected to witness a healthy CAGR in terms of revenue during the forecast period.

Latin America, Middle East & Africa and Asia Pacific regions are the emerging markets in the global hearing amplifiers market. Increasing awareness among the various distribution channels as well as consumers in these regions is anticipated to propel global market growth of hearing aids and amplifiers during the forecast period.

The key players in the global market develop hearing amplifiers in analog and digital forms. Some of the top companies in the global hearing amplifiers market are Sound Hawk, Resound, Foshan Vohom Technology Co. Ltd., Sound world solution, Shenzhen LA Lighting Company Limited, Austar Hearing Science and Technology (Xiamen) Co., Ltd., Huizhou Jinghao Electronics Co. Ltd., Ziphearing among others.

There are many instances where people get confused when talking about types of headsets and the associated equipment. In this article, we are going to help you get a clear understanding of the different types of headsets and the associated equipment. With that said, it is important to note that the names that have been given below, are the actual names that need to be used. Without any further ado, lets get started;

In Ear Monitors

Also known as in-ear (or canal) headphones, these devices sit inside the user’s ear canal, and they deliver great sound quality; they ensure a controlled and precise sound. They also fill the ear’s entrance, thus are very effective at sealing out any unwanted external noise. These devices include a transmitter which is controlled by an audio engineer which then transmits to the belt-pack on the user. The in ear monitors allow freedom of movement and are commonly used by modern pop artists. They’re very small and allow them to comfortably hear the rest of the band, and also themselves (this is what’s known as monitoring or foldback). Apart from artists, these devices are commonly used by audio engineers to hear the mix of the vocals and the stage instrumentation for recording studio mixing and/or live performance.

2 Way Radio Headsets

Two way radio headset is a communication device which can transmit and also receive signals. A two way radio headset allows the user to communicate with other people with similar Two way radio headsets (and are operating on the same channel or radio frequency). 2 way radio headsets are readily available in mobile and also hand held portable configurations. The handheld 2 way radio headsets are also known as walkie talkie headsets or handie talkies. One thing to note about two way radio headsets, is that the user can either transmit or receive signals and not both at the same time.

Two Way Radio Covert Pieces

These are quite similar to the 2 way radios, however, they are much more discreet. 2 way radio covert earpieces are usually used by security personnel as they prefer staying discreet. This type of walkie talkie headset is also ideal for the Door supervisors and security staff.

Wired Show Comms

Unlike Two way radios, these type of communication systems allow for both talking and listening even at the same time. These devices have a closed cup design, meaning they fully cover the ear which helps reduce the ambient noise. Wired show comms come in single muff and double muff versions. They get attached to the belt pack controller which is then physically wired to the system. Because of the cabling that’s involved in wired show comms, there’s less mobility thus are best suited for managers and the static technicians. These specialist communication devices are also commonly used for calling shows.

Wireless Show Comms

These are very similar to the wired Show Comms, only difference is that their belt packs are wireless. The device and the belt pack are compatible which means that the users can freely and comfortably move around, thus are ideal for stage managers, front of house managers, among others. Just like the wired show comms, these devices also allow both talking and listening at the same. With that said, you should know that the wireless show comms are relatively more expensive than the wired show comms. Some of the other applications for these devices include, but not limited to; security personnel, broadcast, marines, theater, and colleges. They can also serve as convenient walkie talkie headset for events.

Radio Performer Headset

This is the device that’s used by presenters and performers. This device allows for the user’s voice to get fed into the sound system where the audience can get to hear them. This device is usually used in conjunction with the radio belt pack system. Most of the devices used today are generally very thin and skin colored which helps reduce visibility when the performer is on stage.

Presenter Talkback

These are the small ear pieces which you see the lead presenters on TV talk shows wearing. This device allows the producer (of that particular TV talkshow or program), to communicate to the lead presenter and update them on the show’s progress. This may be done using a system known as in ear monitoring. Alternatively, wireless show comms systems can also be used.

This news is making quite a buzz within the stock market forums, With two of our big players in our industry set to merge, this is huge news! Yes, Sepura have had their problems this year and Hytera have increased their market share, but we are not sure is this is good news or bad?

Another Asian corporation is set to hoover up a Cambridge UK technology company in a state of financial flux.

Communications technology business Sepura confirms it is in talks with Chinese company Hytera Communications Corporation Ltd.

It will be an all-cash deal but the acquisition price will be moderate because digital radios company Sepura is in a mess because of cash liquidity issues.

Sepura revealed the takeover talks after its share price spiked more than 25 per cent having nosedived in recent times due to cashflow issues and order delays.

Hytera is a world leading solution provider of professional mobile radio communications and operates globally.

Late today, Sepura issued a statement on London Stock Exchange confirming it was in preliminary talks with Hytera regarding a possible offer for the entire issued and to be issued share capital of the company.

Hytera confirmed to the Sepura board that any offer was likely to be solely in cash. The usual caveats were issued that there was no certainty any deal would go through and shareholders would be updated on new developments.

Founded in 1993 in Shenzhen, China, Hytera has grown to be a key player in the PMR (Professional Mobile Radio) communication industry with a large customer base in more than 120 countries and regions across the world.

In China, Hytera’s market share ranks first among Chinese manufacturers while globally Hytera has reached second place in the overall terminal category.

As one of the few corporations that masters TETRA, DMR and PDT technologies, and produces all series of products and solutions of all these mainstream digital protocols, Hytera leads in the draft of digital trunking standard in China.

Its acquisition of the Rohde & Schwarz TETRA business in August 2011 further strengthened its competitive edge in TETRA market.

Hytera has established a global sales network with 30 branches in the US, UK, Germany, Australia, Brazil and other territories and through  600+ partners across the world.

Hytera has an R & D team of over 1200 engineers in five research centres. Sepura won the Business Weekly Awards Business of the Year title in March after a record-breaking

2015 but hit liquidity problems this summer and has temporarily lost its CEO Gordon Watling to ill health.

Sorry, but you’ve been had. Although many manufacturers boast that their radios can reach amazing distances, this is, in almost every instance we’ve encountered, a fallacy.

How is this legal, you may ask?

Essentially, your radio quite probably could work over a range of 25 miles, but that is a theoretical estimate, working on the assumption that the myriad variables that affect two-way radio signal (such as atmospheric conditions, topography, objects in the way and etc) are simply not in effect.

All of them. At the exact same time.

So, assuming that you used your two-way radio in a vacuum, where weather didn’t exist and no obstacles, man-made or otherwise, were present, you would be able to communicate with someone else who was further away in that impossible vacuum, maybe even 25 miles away, but otherwise? Forget it.

The fact is that the average two-way radio has a range of between one and two miles and not much more (maybe three, but we’re not making any promises). CB radio fares significantly better, largely because it makes use of large aerials. Now, Signal-boosting equipment can be used to improve your two-way’s performance (for example, repeaters), but such equipment is expensive and hard to obtain for legal reasons.

There are, however, a few factors that can have an affect on your radio’s range. The frequency being used, the power output, the size of the antenna, the complexity of the signal being sent, signal interference, background noise and (as we wrote earlier) objects in the way are all factors that can improve (or hamper) your efforts to get your signal to reach as far as possible.

So, talking on your radio whilst in the car will have a deleterious affect on your signal, as will deliberately walking through wooded areas or places with a lot of rocks/mountains if you can take an easier path.

However, a larger antenna (if you’re tech orientated, the antenna can be replaced with a better one – although this should only be attempted if you are

  1. a) Sure about licensing laws

And

  1. b) Tech savvy enough to void the warranty and not regret it later, can really add a few hundred meters to a radio’s range, as can a switch in frequencies.

Also, your choice of VHF or UHF radio will have an affect as well, a UHF signal, for example, generally penetrates buildings and objects better than a VHF signal, whereas VHF is better for outdoor use where there is a lot of open space to transmit across.

Having said/written that, even in optimum conditions, you are extremely unlikely to transmit over a distance of 25 miles. Sorry.

As an aside, mobile phones don’t suffer from this lack of coverage, largely because cell towers are in place that bounce the signal from one to the other and thus carry it across a far larger area, your mobile is still your best bet to break that 25 mile mark, we’re afraid.

If you really must use radio communications over long distances, we recommend going to the Website 2wayradionline

Hope that helps.

If you are looking for a security earpiece with a mic, then you will need to know the varieties available out there. While some types are more expensive than others, what ultimately matters is the quality and durability of what you get at the end. Below is a look at what you get out there:

One wire kit

With this one, there is only a single wire, which emerges from the radio, runs through the PTT and then ends where the earpiece starts. This makes for a simple yet effective look. As for the length of the cable, the one wire kit has a piece that runs between 28 and 34 inches. This means that you have at your disposal a length sufficient to cover the distance between your ears and the waist without any kind of stretching or straining. Of course, the reach of every security earpiece will be determined by the height of the person wearing it. The one wire kit is great for an average height and will work for anyone 6 feet and below.

Most one wire kits come in the original D and G shapes. There are some fancier designs out there as well if that’s what you are looking for.

Two wire kits

As the name suggests, there are two wires involved in this scenario. One runs to the Push to Talk (PTT) button. The other runs up to the earpiece, making for a good looking dual connection. For the purposes of discretion, you are allowed to wear this cable partially disguised within your clothing. One wire will emerge from the radio, rising up your back to the ear in a way that keeps you comfortable. The other cable runs from the radio, up the length of your hands and terminates at the cuffs if you are wearing a long-sleeved shirt or sweater. In terms of length, the two-wire kit is essentially the same as its one wire counterpart, with a reach of 30 to 34 inches. This accounts strictly for the length of each individual wire, and allows the unit to comfortably cover the areas between your waist and the ears. Two wire kits commonly come in the form of an acoustic tube that many who know a little about surveillance will be able to understand.

3 Wire kits

Here, you have three wires coming off the radio. The first wire will terminate where the earpiece is built. The second will end where the Push to Talk button is located. The last will end at a connection with the mic. As with the two wire kits, this one is worn under ordinary clothing, with a cable for the mic, earpiece and PTT button. There is really no standard length for all the three wires and there is no guarantee that all of them will be equal in length, but there is a sense of flexibility in the way you get to use the piece. Always try on sample pieces before making a purchase at a store. Over the internet purchases are trickier but then the measurements will be highlighted long before you order.

Understanding the functionality of PTT technology

Push to Talk is a cutting-edge technology that allows for direct communication between parties at agreed-upon frequencies and distances. The greatest thing about PTT is that it switches communications from duplex to half duplex. This means people do not talk over each other but get to alternate between speaking and listening. PTT is able to loop in two or more speakers at an instance of communication, allowing for conference-like types of engagements between participants. This streamlines communication. Most enterprises prefer this approach to communication because there are no limitations in terms of allotted minutes. As such, there is absolutely no need to stay within the confines of a data plan, which would be both expensive, inconvenient and rigid.

There is no such thing as a right security earpiece. What works for you may not work for all other parties across the board. While your budget matters a lot, you are looking for something that works optimally and stands the test of time. The three types mentioned above are alright if you are looking for something that works all the time. Remember, prices will vary across brands and models.

Back in the day, around 2006, the Heathrow and Gatwick radio systems were the envy of many, many businesses, a cutting-edge Motorola analogue trunking system with individual and group setup, that could broadcast messages out across the site or talk to individual radios, something that is taken for granted these days with our digital systems. The Gatwick system has been upgraded and been given the digital touch.

US-based Motorola Solutions, along with its authorised channel partner Servicom, has debuted its new digital mobile radio (DMR) system, Mototrbo Capacity Max, at London Gatwick Airport.

Designed to provide enhanced voice and data communications, the newly installed system connects 1,300 people in the airport’s airside and groundside teams.

Mototrbo Capacity Max will also double the capacity of Gatwick’s current analogue network.

Various applications, such as TRBOnet PLUS and iBeacon, were given along with Mototrbo Capacity Max to improve its data performance.

TRBOnet PLUS is a dispatcher application that allows voice recording, mapping and event logging in the control room, while the iBeacon indoor positioning application sends alerts to individual radios based on location.

Gatwick Airport IT project manager Simon Telling said: “We chose Motorola Solutions’ Mototrbo Capacity Max system not only for how resilient and secure it is, but because of the flexibility it offers us now and into the future.

“We have experienced significant growth over the past decade and we are now approaching the limits of our previous analogue system.

“Migrating to scalable, digital communications will double our capacity and bring new capabilities that will help us improve efficiency and safety for staff, retail partners and passengers across the airport.”

The new Motorola solution will also enable Gatwick’s central controllers to send off the closest employee to an incident, saving time.

The airport recorded more than 4.6 million in passenger traffic in July.
