A Safer Way to Listen to Music
Live Science
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
on earbuds
Reader's Digest
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'
Yahoo! News
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
Hearing Loss
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
Men's Health
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
ComputerWorld
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. ...
Asius'
ADEL earbud balloon: a new earphone technology
TechnoTrack
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
Popular Science
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
SmartPlanet.com
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
Gizmodo
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
Popular Mechanics
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 ...
Miniature Balloon Ear Buds Take A Beating So Your Ear Drum Won't

high to get your jam on. It also cuts down on all that unsightly
“leathering” on your eardrum…

Through the Diaphonic Lens
Sound+Vision
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.
