Story
The MDHearingAid
®
was invented by a board-certied Ear, Nose, & Throat
physician in Chicago, IL. He would encounter patients in his daily practice
who would benet 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 ampliers 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).
