Stephen Ambrose invented the World's First Wireless In-Ear Monitor Technology (IEMs). Already a professional musician at age 12, he began modifying swimmer's earplugs. By mixing in tiny speakers and clay he completed his first In-Ear Monitor in 1965. This was the first time full spectrum high fidelity sound was delivered within a fully sealed ear canal by an In-Ear Monitor. Touring for decades with hundreds of performers including Stevie Wonder, Simon & Garfunkel, Diana Ross, Rush, Steve Miller, Kiss and many others, Stephen perfected and commercialized his IEM designs and was the sole provider of IEMs to the professional market for well over a decade.
During this journey it was found with great concern that there is over a 77% increased risk of hearing loss due to the use of personal listening devices. This set Stephen on a mission which began extensive research with grants from the National Science Foundation and National Institutes of Health. The results where staggering as they discovered the exact mechanism by which people were destroying their hearing.
A solution was found to solve this growing epidemic, he invented and patented a revolutionary "second eardrum" called the Ambrose Diaphonic Ear Lens (ADEL™) which absorbs harmful in-ear pressures, thereby preserving the health of the human ear, thus allowing people to more safely hear sound the way it needs to be heard.
Stephen, founded Asius Technologies. In a short period of time Asius was chosen as a Wall Street Journal Startup of the Year Finalist, Auto Desk Inventor of the Year and Winner of the Denver Challenge Cup in healthcare innovation.
Fast forward to today - ADEL is the world's first and only patented technology that safely delivers a louder, more spacious and richer sound in professional In-Ear Monitors & Earbuds - all while avoiding the risk of hearing damage that can be caused by traditional earbuds.
Stephen Ambrose, invented a new kind of in-ear monitor, an advanced next generation earbud used by professional musicians on stages around the world. This invention, this new product will become the future of earbuds.
The Facts: Earbuds cause hearing loss... Stephen discovered that when the ear canal is sealed by an earbud, the speaker vibrations create acoustic pressure. In the confined space of the closed ear canal, these vibrations become harmful amplified pneumatic pressures and cause the eardrum to move with an amplitude thousands of times greater than normal. Tiny muscles around the eardrum then tighten to protect the ear by dampening the sound. To overcome this dampening you must turn up the volume. The more the volume increases, the more the eardrum tightens. And so on. And so on.
1.5 Billion People Globally suffer from hearing loss. A large percentage of the hearing loss is noise induced, not reversible and permanent.
The Solution - Stephen found a way to break the cycle. It’s called ADEL and it’ll change the way you hear music. This technology adds a second eardrum into all of our earbuds. This second eardrum takes the punishment of the pneumatic pressure caused by sound in the ear canal, and delivers clear, crisp sound that’s unlike anything you’ve ever heard.
Think about turning down the volume, yet hearing more!
ADEL, it’s quieter – your listening level comes down from 25% to 50% of the amplified in-ear power/volume levels of traditional listening devices (per studies conducted at Vanderbilt University Medical Center). And by not prematurely tightening in-ear muscles, which can dramatically compress the volume, loud sounds actually sound louder and require less overall volume levels.
The results from the Vanderbilt University Medical Center show that using ADEL technology allows listeners to enjoy Enhanced Loudness Perception (lower volumes sound significantly louder and better). This provides a louder yet safer, high fidelity listening experience at greatly reduced power levels with no perceived loss in volume.
HELM is dedicated to the future of positively impacting hearing health across the globe with a new generation of in-ear hearing products working with a variety of breakthrough technologies like the ADEL solution.
