The MDHearingAid
®
Story
The MDHearingAid AIR was developed by a board-certied Ear,
Nose, and Throat physician in Chicago, IL, Dr. Cherukuri. He
encountered patients in his daily practice who would benet from
hearing aids, but many simply couldn’t afford the thousands of
dollars needed to pay for them. As a physician, he knew the
effects of untreated hearing loss: depression, social isolation,
anxiety, and other symptoms consistent with Alzheimer's disease.
Dr. Cherukuri 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.
He evaluated numerous hearing aids and sound ampliers,
including those seen on television. He found almost all of
these devices only amplied low frequencies (below 1000 Hz);
however, the majority of hearing loss is in the higher
frequencies (1000-4000 Hz), those most related to
the human voice.
