Story
The MDHearingAid
®
was invented by a board-certied Ear, Nose, & Throat
physician in Chicago, IL. He would encounter patients in his daily practice
who would benet from hearing aids, but many simply couldn’t afford the
thousands of dollars often needed to pay for them. As a physician, he knew
the effects of untreated hearing loss: depression, social isolation, anxiety,
and symptoms consistent with Alzheimer’s dementia.
He set out to nd a reasonable solution that could help with the most
common types of hearing loss at a reasonable price. He was looking for a
“one-size-ts-most” hearing aid similar to reading glasses that can easily be
purchased at the drug store.
After evaluating numerous hearing aids and sound ampliers including those
seen on television, he found, without fail, that almost all of these were found
to only amplify bass / low frequencies (<1000 Hz) and were not useful in
amplifying the frequencies related to the human voice (1000-4000 Hz).
