Sonion A/S Signs Patent License Agreement With Asius Technologies, LLC
Sonion A/S ("Sonion") and Asius Technologies, LLC (“Asius”) announced today that they have reached a license agreement on an international portfolio of patents owned by Asius. The patent license agreement includes Asius’ United States Patent Publication Nos. US 2009/0028356 A1; US 2010/0322454 A1; US 2011/0228964 A1; and, portions of US 2012/0057734 A1 and will grant Sonion worldwide access to the patent portfolio for use in the field of hearing aids, hearing aid assemblies, and hearing aid components including the diaphonic valve and pump design that uses the hearing aid speaker sound to inflate a bubble in the ear canal.
"We are pleased that an industry leader such as Sonion will be the first to license this patent portfolio and realize the commercial success this technology will provide the hearing aid industry," said Stephen Ambrose, President of Asius. “We are not just introducing a new component but an entirely new means of coupling sound to the ear that will impact all hearing aids and even earbuds. In fact, we have been approached by several companies interested in licensing ADEL for application to earbuds as well as “hybrid hearing aids” that provide recording studio sound." said Mr. Ambrose. "Ultimately, our goal was to create a hearing system that would replace uncomfortable and ineffective earmolds with a bubble that dramatically improves the overall listening experience for all hearing aid wearers."

Earbuds Provide Better Fit
The two most important things when trying to find the perfect headphones are sound quality and fit. Some headphones, like Beats by Dr. Dre, are supposed to provide superior sound quality, but they’re much larger and bulkier to carry around. Many people choose earbuds instead, but with headphones like these there tends to be a fit-problem, since everyone’s ears are slightly different.

Inflatable Earbuds Reportedly Coming to Apple
Sometimes, the cushion on the earbuds is too big. At other times, they're too small. Why can't there just be a reasonable solution for everyone. Well, that moment may finally be here as Asius Technologies is going to come out with inflatable earbuds, which "

A Safer Way to Listen to Music
An audio pioneer who has worked with the likes of Stevie Wonder, Bon Jovi and Pink Floyd, Stephen Ambrose is on a quest to perfect sound quality. His most recent innovation is a modification for ear buds, hearing aids and other in-ear devices that alleviates pressure and its subsequent "listener fatigue" — the discomfort and even pain some people experience with devices that seal the ear canal.

Problem:Loud music - Solution:A new spin
You take your music everywhere, but ordinary earbuds can damage your hearing. They completely seal off your ear canals, triggering a
reflex that makes the sound seem quieter than it actually is. To compensate, you crank up the volume. A soft plastic membrane from Asius Technologies, called the Ambrose Diaphonic Ear Lens (ADEL), solves the problem...

New earphone technology aims
to cure 'listener fatigue'
If you wear earbuds frequently for long periods of time, you've probably noticed some strain, discomfort, or even pain, known as "listener fatigue." Engineers have not only discovered why this happens but invented a solution that they say resolves the problem. Announced May 13, new research by engineers Stephen Ambrose and Samuel Gido at Asius Technologies in the US discovered that sealing an earbud in your ears can increase the pressure on the eardrum by up to 1,000 times...
New earphone technology could be the answer to 'listener fatigue'
Hearing Aid News
It’s no big secret that wearing in-ear devices, such as stereo earphones or hearing aids, can cause the ears to hurt over time. According to the engineers at Colorado’s Asius Technologies, however, this isn’t due simply to a poor fit or high volume levels. Instead, it’s caused by an “acoustic reflex,” that no amount of earbud-reshaping or decreases in volume will alleviate. ...
Cause of Headphone, Hearing Aid Fatigue Diagnosed
Engineers at Asius Technologies in Longmont, Colorado have discovered what they believe is the factor behind listener drowsiness caused by on-ear headphones and hearing aids. Their conclusions, together with implied fixes, were presented that past weekend at a meeting of the Audio Engineering Community in London, U.K. ...

Stop the Headphone Hurt
Andrew Daniels — Have you ever noticed that your ears start to hurt after listening to your iPod for hours on end? It might have something to do with that nonstop hair-metal playlist you made, but it’s more likely due to “listener fatigue”—a phenomenon that Colorado researchers have been studying. ...
Self-Inflating Earbuds Could Save Ears -- and Tunes
Kevin Lee — We've all been on a train listening to our tunes, then as the rail car starts banking on a turn, the wheels start screeching, and our first instinct is to turn up the volume. We think that more sound-isolation--in the form of in-ear headphones--will help, but as Stephen Ambrose tells it, we actually want balloon-like earphones that disperse the vibrations that normally bounce around inside of our heads. ...
ADEL earbud balloon: a new earphone technology
According to researchers at Asius Technologies, though, the discomfort you experience after extended periods of earphone listening isn’t caused by faulty design or excessively high volumes, but by “acoustic reflex.” Every time you blast music through earbuds, your ear muscles strain to reduce sound waves by about 50 decibels, ...

Inflatable Balloon-Like Earbuds Use Natural Reflexes in the Ear for Fit
Dan Nosowitz — Our sister publication, Sound + Vision, has an in-depth look at an earbud even more peculiar than the silicone-filled Sonomax Eers. This balloon-like creation notes the natural muscle-tensing reflex of the ear and is designed not to trigger it, meaning you need less volume for the same effect--ultimately much safer on the hearing-holes. ...
Diaphonic Ear Lens: Inflatable earbuds combat listener fatigue
Janet Fang —This past Saturday, Stephen Ambrose and Samuel Gido of Asius Technologies described how sealing a speaker in the ear canal substantially boosts sound pressures and how a modified ear-tip can help alleviate that effect. ...

These Balloon Earbuds Are Better Than Your In-Ear Earbuds
Casey Chan —In-ear earbuds are everywhere, hell, I'm using them right now. But they're not ideal because they trigger a natural defense mechanism in your ears that tenses up your ear muscles and dampens the sound by as much as 50 dB. ...
The Tiny Lens That Could Stop Hearing Loss From Earbuds
Mike Ryan — Since the rise of the iPod, earbud headphones have become unavoidable—as have concerns that they are causing widespread hearing loss. So Stephen Ambrose invented a microscopic lens that absorbs the vibrations of sound while still allowing full audio ...

Through the Diaphonic Lens
By Michael Berk Stephen Ambrose's music teacher father once posed a difficult question to his son: "What instrument don't they make anymore?" The younger Ambrose was stumped. "The chamber," his father responded. Ambrose filed the exchange away, not quite sure what to make of it, and went on to a career as a musician and sound engineer.
