Are your earbuds making you deaf? 1964Adel says yes, so it created a solution

This was posted on %link% just a few days ago and we thought it was interesting

Those tiny earbuds you bring along with you here, there, and everywhere are causing you to go deaf. At least that’s what audio specialist, and in-ear monitor pioneer Stephen D Ambrose would have you believe. To save you from the dangers of the common earbud, Ambrose and his team at 1964|Adel have created an entire new wave of %link% designed with patented technology to be safer for your eardrums, all of which are making the rounds in a new Kickstarter campaign.

The link between hearing loss and headphone use being drawn here is not a new one. For its part, 1964|Adel singles out a study from an L.A. Times report which cites an increase in hearing loss for U.S. teens in the last 15 years from 30 to 77 percent. The study in question ruled out ear infections and external environmental factors as causes, pointing instead to the higher prevalence of portable audio players, though it stopped short of specifically laying blame. That said, there are plenty of other studies blaming the blasting of headphones as a major contributor to hearing loss.

But Ambrose argues that hearing loss from in-ear headphones and %link%, specifically, is different due to the way they isolate the eardrum inside the ear canal. In the video below, Ambrose claims it’s not acoustic pressure (i.e. loud noises) that causes hearing loss, but the pounding of air pressure from the moving driver being sealed inside your ear canal, causing “pneumatic pressure” from the movement of the driver itself.

In response, Ambrose and 1964|Adel have proposed a new way to solve the very hearing loss epidemic Ambrose claims to have helped create with his original in-ear monitor design; four ways to be exact, stemming from four different headphone series. The new headphones employ 1964|Adel’s patented RealLoud Technology, which incorporates a “second eardrum” inside the earpiece designed to take the brunt of the air pressure to protect your real eardrum. The company even claims the design makes audio “sound louder,” requiring a lower overall volume level.

The first, and most affordable solution in the arsenal is the new Adel Control, a modular earphone that allows users to adjust features like bass and external noise to taste, tailoring the sound signature. At time of publication, the Control was still available as an Early Bird special for $100, half off the suggested retail price.

Next in line is the Adel Ambient series, which offers 4 multi-driver models, from the entry-level dual-driver Ambient 2, to the Ambient 12 which (you guessed it) is jam-packed with a whopping 12 drivers per side, labeled the “jewel” of the Ambient line. Pricing for the Ambient series starts at $200 for the dual driver set, and goes up to an impressively (relatively) affordable $500 for the 12-driver version, again, priced at half the cost of suggested retail for each. For reference, the quad-driver Westone W40 will run you the same price as the Ambient 12.

Next up are the 1964|Adel U-series, which take the shape of more traditional in-ear monitors, covering the entire ear canal. The U-series starts with a quad-driver pair for $300 — down from a suggested $500 retail price — and the series goes all the way up to the 8-driver U-series 8, which will run you $720. The latter offers 4 drivers for the bass register alone, with two each for the midrange and treble, to create a massive sound.

Finally, the 1964|Adel A-Series includes both 10-driver, and 12-driver models, priced at $1,000 and $1,200 respectively — 40 percent off the claimed MSRP. Like most top-tier in-ear monitors, the A-series are custom tailored to the user’s ears for the ultimate fit and sound, while harboring a RealLoud secondary eardrum for safety.

Not only is 1964|Adel’s new project already funded, but it has already reached its stretch goal of $350,000, which provides an optional inline 3-button mic piece for all of its headphones. All of the new models are slated for release in May of 2015, with the exception of the A-series, which will be available earlier in February.

While we certainly can’t attest to the claim that RealLoud Technology actually makes these headphones safer, they are priced very competitively under the Kickstarter deal. And hey, if they offer competitive sound in their respective genres, what’s the harm in playing it safe, right? If you’re interested in finding out more, or ordering up one of 1964|Adel’s latest designs, you can do so today at its Kickstarter page.

What Is a Covert Earpiece?

Now then ladies and gentlemen, i have one more excellent earpiece piece of writing to read, i know, you do not need to thank me all, just click a social like to the short article to illustrate your appreciation.

A covert earpiece is a miniature earpiece worn by an individual while being effectively hidden from plain view. It operates as a radio accessory in times when a user does not want other people to know she or he is communicating with others using radio earbuds. Also known as an invisible earpiece or a surveillance earpiece, a covert earpiece is often worn by government agents, corporate security personnel, undercover law enforcement officers and corporate as well as government spies.

covert earpiece

While many occupations require the use of a radio headset for communication, a covert earpiece is primarily used in instances where communication is of an extremely private and sensitive nature. This is common in cases of private security details and surveillance projects. Sometimes people also use a covert earpiece to defraud businesses and others. Examples of such instances would include someone using an invisible earpiece to cheat on an exam or to defraud a casino by receiving remote information while playing a game.

On-air television personalities may also use a covert earpiece, which is not distracting to viewers, but allows the person to hear relevant feedback from producers and engineers in order to make sure a taping or live appearance flows smoothly. Individuals may also wear a covert earpiece when making a public speech. By doing so, the speaker can receive important cues or changes in a speech without the audience even being aware that communication is taking place between someone located behind the scenes and the individual delivering the speech.

Some covert earpieces are accompanied by a discreet microphone, which enables two-way communication. These are commonly used by security forces with a need for such communication, particularly during surveillance operations. These types of accessories are not only convenient because they feature hands-free operation, but also because they allow undercover security forces to blend in with crowds without having to use a visible walkie-talkie system of communication.

A covert earpiece does not contain any visible wires and is designed to fit inside the ear without being noticeable to the general public. Some devices are even designed to fit on a pair of eyeglasses while amplifying sound inside a person’s ear. An inductive wire is sometimes worn around the person’s neck, but is covered by clothing so as not to be discovered by onlookers. This wire is not connected to the covert earpiece, but connects to a separate radio device that helps modulate sound.

(EO) What Is an Acoustic Tube Earpiece? (filler)

While many of my readers are interested by some of my own writing, here is one i discovered while surfing around blogger.com it’s far better written than I might ever dream to achieve. Maybe someday I will get to this level, you never know.

An acoustic tube earpiece is a special type of listening device that features a thin tube that helps transmit sound, which often fits behind the ear and is attached to an earbud placed inside of the ear. Such devices allow for hands-free operation of a two-way radio or may be used in mobile communications or television broadcasting. Sometimes referred to as a radio headset or a tactical earpiece, some also refer to this device as a surveillance earpiece.

acoustic tube earpieceThis particular type of radio accessory is commonly used by security personnel and may feature an earpiece that includes a hidden microphone, making it highly useful for two-way communication. The earpiece does not have to include a microphone, however. Most are constructed so the tubing fits discreetly and comfortably behind the ear, which makes it useful for covert surveillance.

Though commonly used in security and covert operations, some also prefer an acoustic tube earpiece for mobile civilian devices, which include personal audio devices and mobile phones. Television broadcasters are also known to wear these earpieces, as they allow for communication between producers and broadcasters without being visible to viewers. Most are comfortable to wear and efficiently reduce background noise. They are also known to be particularly useful in noisy environments, as quality models make it easy for users to comfortably listen to incoming audio despite high environmental noise. Depending on the manufacturer, some may also feature volume control buttons on the cord.

Aside from a covert design and a high sound quality, one of the primary benefits of an acoustic tube earpiece is its durability. The sturdiness of some of these earpieces is often preferred over earpieces that feature exposed wiring, as well as certain wireless earpiece devices. Sturdy tubing protects delicate wiring crucial to the device’s operation, which is particularly useful in occupations where the person wearing an earpiece may be required to engage in rigorous physical activity while wearing it. Such earpieces are also known to outlast other wired devices.

In order for an acoustic tube earpiece to work, it must be plugged into a wireless receiver, which is usually hidden beneath a person’s clothing. Some are also accompanied by microphones, which are covertly placed on the user’s shoulder or at the wrist.

FIVE REASONS TO MIGRATE TO DIGITAL TWO-WAY RADIOS

In the beginning, there was analog technology, which uses frequency modulation (FM) to produce a continuous wave with the voice signal. An analog two-way radio works as both transmitter and receiver, with that continuous wave in between. Analog has been the primary technology platform since the initial development of wireless communications.

Analog radios have been used for business applications as far back as 1933.

  • Analog Advantages: The integration of such a simple system into a single computer

chip has dramatically reduced the cost of analog radios.

  • Analog Disadvantages: The analog radio system has many functional limitations, and

the technology has been around so long that the scope of possible innovations is virtually exhausted.

ALONG COMES DIGITAL

Digital two-way radios operate by encoding, transmitting, and decoding sound waves. The signal is represented by binary numbers—1s and 0s—that correspond with voltage values. Inside the radio, the vocoder—an analysis/synthesis system used to reproduce human speech—encodes the transmission. The radio sends the signal, and the vocoder on the receiving end decodes it.

In addition, the software in digital radios contains an algorithm that recognizes the difference between voice and background noise and cancels undesirable audio for clearer, cleaner sound quality. Digital two-way radios can also include software applications that integrate into existing computer networks and phone systems. As a result, digital radios can enable a multitude of additional functions, including GPS, text messaging, and other information sharing, communications, and operations programs and capabilities.

By proactively transitioning to digital radios now, your organization will enjoy greater benefits immediately, and your fleet is ready for the high-efficiency, app-driven innovations coming in the future.

FIVE REASONS TO GO DIGITAL

  • Improved Audio Quality • Enhanced Clarity throughout the Coverage Range
  • Greater Efficiency • Extended Battery Life • Applications that Add Functionality
  1. Improved Audio Quality: Digital technology reduces external background noises during

transmission, thereby making the digital technology platform ideal for situations such as

noisy manufacturing and processing plants, or outside in windy conditions.

  1. Enhanced Clarity throughout the Coverage

Range: While an analog radio is capable of producing a clear signal within its peak performance range, once the signal moves too far from the transmit point, the analog audio will slowly fade out until it is unrecognizable. By contrast, a digital signal stays much stronger and clearer to the limits of the coverage range.

  1. Greater Efficiency: Digital radios operate in

Dual-Capacity Direct Mode (DCDM), which means that radios can share the same channel by alternating time slots. These time slots move incredibly fast, and since they alternate, more simultaneous talking paths are possible on each channel with no degradation. Plus, key information such as unit ID, status buttons, and enhanced text messages can be embedded into a single digital radio channel. In many cases, migrating from analog to digital allows users to increase talk paths without a repeater.

  1. Extended Battery Life: Since digital radio transmitters are not constantly “on,” digital

radios generally have a significantly longer battery life than analog models. When events run all day, that can mean the difference between efficient communications for the full cycle or the headache of a number of dead batteries that need swapping out and recharging.

  1. Applications that Add Functionality: Software applications are available to optimize digital

platforms using integrated Internet Protocol (IP) networks. For example, some of the leading app providers for Motorola MOTOTRBO digital radios include:

TABLETmedia

NeoTerra Systems

Twisted Pair

TurboVUi

Teldio

MOVING TO DIGITAL

For those switching from analog to digital, there is good news: Digital platforms provide a migration path that allows for simultaneous use of digital and analog radios. Backward compatibility allows organizations to gradually replace analog devices with newer digital models without the added stress of shifting to a new system. Also, many analog radio accessories are compatible with digital devices.

THE MOTOROLA CP200 AND CP200d

The existing CP200 is one of the most popular two-way radios ever produced! So the question is: How can you improve on the Motorola CP200? The answer: By creating a version that leverages all the benefits digital delivers.

Introducing… the CP200d digital two-way radio, a new model that retains the same simplicity and durability that have made Motorola’s CP200 the industry standard for years. The new CP200d uses a nearly identical form factor with similar operation. Plus, this highly flexible digital model is backward compatible, so it uses the same chargers, batteries, and speaker-microphones.

Motorola is adding sensible options to your two-way radio fleet by offering the existing CP200 device in the CP200d digital-capable version that can be fully converted from analog to digital operation at a later date. That means you can use a phased migration approach by using your new CP200d as an analog device now, and then with a simple programming change, switch to digital at any time in the future. Or, you have the option to take out-of-the-box delivery of the CP200d as a digital device from the get-go.

THE TALE OF THE TRBO

MOTOTRBO is Motorola’s next-generation system of digital portable and mobile radios, repeaters, and accessories. Thanks to the advantages of digital technology, this professional line delivers advanced performance to increase capacity and productivity while integrating voice and data communications.

Versatile and powerful, MOTOTRBO combines the best of two-way radio functionality with the latest digital features that deliver ease of use and added performance to meet your communication needs from the field to the factory floor. With exceptional voice quality and long battery life, MOTOTRBO keeps your work teams connected when communication is a must.

Kickstarter campaign launched for an earpiece together with biometric sensors

What would you do if i said I had found a earpiece piece that is not only interesting but informative as well? I knew you would not believe me, so here it is the enlightening, superb and fascinating article

Research and development firm Sensogram Technologies announced it has launched a Kickstarter campaign to raise $250,000 to supplement the manufacturing and refine its wearable health and fitness device, SensoTRACK.

SensoTRACK is able to simultaneously measure and monitor heart rate, respiration rate, oxygen saturation and blood pressure in real time, as well as many other parameters including calories burnt, step count and geophysical location.

Launched on October 14, the Kickstarter campaign is set to run for 60 days through December 12.

Available in six different colors, SensoTRACK will initially be offered in limited availability by February 2015, then expand to full-scale production in the second quarter of 2015.

Though the suggested list price is $245 per device, it is now available for pre-order on Kickstarter for $199.

Operating either as a stand-alone device or a tablet to upload data to a secure cloud server, SensoTRACK can be worn on the ear to wirelessly sense, monitor and track a user’s performance.

SensoTRACK’s algorithms analyze, interpret and present the data in a dashboard display, while the platform allows users to share fitness routines with other users via the cloud platform.

Radio Communication with First Responders Pending at Lenape Tech

Article of the Day………ok so i haven’t got a piece of writing each day, but if i get a chance I’ll post posts I find fascinating. Lucky enough here is one of these articles that I read and needed to share. If you enjoy it as much as me, please add one of the special social media likes, you know the one which tells everyone you loved something, rather than you sat on your arse and watched TV!

Two-way radio communication at a local technical school would greatly improve school security, according to one local official.

Lenape Technical School Special Programs Coordinator Carla Thimons further explained the need for such during discussion on the Manor Township school’s $18,000 Pennsylvania Department of Education Safe School Initiative Competitive Targeted Grant award.

“These will truly help us feel better about safety overall, because communication is key,” Thimons said.

She said several programs at the technical school provide a unique challenge where areas of the building would not be able to listen to announcements over the public address system, and the radios would provide necessary internal communication with teachers and staff.

Thimons said the grant funds were accepted by the Joint Operating Committee last month, and funding received, but the radios have not been purchased yet. She explained officials want to coordinate efforts with the Armstrong County Department of Public Safety to ensure that communication will be loud-and-clear.

“We want to determine the best purchase,” Thimons said. “We have an idea in mind what we want, but we want to coordinate with (the Department of Public Safety.)”

Radios are to be expected to be carried in the school hallways by officials by the start of the 2014-15 school year.

Thimons, who has been Special Programs Coordinator for 10 years and was previously the technical school’s principal, coordinates special education, grant writing and safety procedures at the school.

Besides the two-way radios, Thimons said school officials are planning to hold school wide drills, including a mass-evacuation drill.

Joint Operating Committee members also unanimously approved the hire of Night Watchman Samantha Walker, retroactive to March 7.

Principal Karen Brock last month said the school used to have night watchmen, but another one needed to be hired to replace that individual.

Armstrong School District also received Safe School Initiative Competitive Targeted Grant funding in the amount of $25,000, and put the money toward the purchase of new and updated security cameras “as another layer of security throughout the district,” according to School Superintendent Stan Chapp in March.
Director of Technology and Information Services Anthony Grenda said about 16 surveillance cameras will be added to the interior and exterior of Elderton and Shannock Valley Elementary Schools. He hopes those cameras are installed by the end of the current school year. Several have already been installed, he said earlier this week.
Apollo-Ridge and Leechburg Area School Districts also received $25,000 in grant funds.
Earlier this year, Armstrong also received $40,000 in the state’s Safe Schools Grant Program for utilization of a school police officer. Those officers have also been already utilized throughout the district.
The Lenape Tech Joint Operating Committee meets again Thursday evening, beginning with a 6:30PM public budget session at the school.

Where Do We Get The Word ‘Earpiece’ From?

The word ‘earpiece’ is obviously a joining of the words ‘ear’ and ‘piece’, the term was probably originally coined for eyeglasses at some point in the 18th century, but it also applies to things like old style phone receivers and doctor’s stethoscopes.

British optician Edward Scarlett is thought to have developed the first eyeglass earpieces sometime before 1727. However, this invention didn’t catch on until the early 19th century, so it is probable that the word ‘earpiece’ fell into popular use around that time.

For comparison, American inventor Nathaniel Baldwin built the first radio headphone set in 1919, almost a hundred years later. The basics of earpiece design have existed since that time, so the word ‘earpiece’ was almost certainly used at that point, although it would not have denoted the same device that we now think of today.

Bluetooth headsets, colloquially referred to as ‘earpieces’, were first made commercially available in the early 2000’s and since that time, the term has proliferated. By and large, in the 2010’s, the word ‘earpiece’ tends to refer less to headphones and earphones (although it is still technically accurate terminology) and increasingly solely denotes Bluetooth headsets.

As for the word itself, the word ‘ear’ is actually a derivation of the old English word ēare. It is derived from the same root word as the Norse word eyra and is also cognate with the German word ohr and the Latin auris.

The word ‘piece’ has been in use as far back as the 11th Century AD and comes from the Old French word pece (which is itself of ancient Gaulish origin). It probably also has linguistic ties to the ancient Welsh word peth (meaning ‘thing’).

In the future, it is likely that the word ‘earpiece’ will continue to refer to wearable technology until such time as the word exclusively denotes a wearable device. However, this is purely conjecture on our part.

The other uses for the word will likely remain standard English that simply isn’t used on a daily basis. An example of this would be words like ‘Sellotape’, ‘Tannoy’ and ‘Hoover’, all of which are brand names that do not denote the actual object in question. Correctly, a Hoover is a vacuum cleaner, a Tannoy is a public address system and Sellotape is sticky back plastic. However, almost nobody uses those terms anymore in a casual setting (Alan Partridge and the odd Blue Peter Presenter notwithstanding). 

How Does Two Way Radio Work? (Asked by Neil from Reading)

Hi Neil,

Did you get a two-way radio set from Santa by any chance? Lol.

Anyway, onto your question…

A two-way radio, basically, is a radio that can send and receive signals. If a radio can both transmit and receive, it is known as a transceiver (see what they did there?) Two or more users can use a transceiver in order to communicate on a shared channel.

Essentially, a two way radio works by receiving radio waves through the air and broadcasting a return signal. The antenna on the radio houses a series of electrons, which dictate the channel being picked up by the user (different groups of electrons will respond to different channels). These electrons translate the radio waves into electrical impulses, which are then fed to a small processor. The processor then converts the impulses into a signal and the radio’s speakers then play that signal. The whole process, amazingly, is pretty much instant.

Two-way radios convert sound into radio waves and also convert radio waves into sound. Ergo, I can speak to you, like so:

Chris: “Hi Neil. Can you hear me? Over”

Once I push the PTT (push to talk) button and speak, the vibrations of my voice shake a small membrane inside my radio’s microphone (not a million miles removed from the one that exists in the human ear). My radio’s processor then converts those vibrations into a simple electrical signal. The radio pushes the signal to the antenna, which then pushes it out on the audio channel selected.

The electrons in your antenna become excited (steady on there, fella!) and translate the waves into electrical impulses, which are then ‘decoded’ by the processor and played out via your speakers.

So, you hear this on your radio and you reply.

Neil: “Hey 2wayradionline. Yeah, I can hear you just fine. Thanks for the answer. Over”

Whereupon the entire process takes place all over again.

And so on…

I hope that answers your question. Have fun, 2wayradionline.co.uk!
