Dr. Cherukuri worked with world-class Doctors of Audiology and Audiologists
to create the MDHearingAid
®
AIR. Built to exacting specications, the
MDHearingAid
®
AIR includes advanced technologies found on hearing aids
costing thousands of dollars more such as:
• Advanced feedback cancellation to reduce and eliminate "whistling"
• Advanced compression technology to magnify soft sounds and dampen
loud sounds
• Advanced noise reduction that reduces noises embedded in speech and
maximizes sound quality
• Digital amplication to accurately reproduce speech and sounds to enhance
listening comfort
• A Telecoil setting for easy use with compatible telephones or looped
environments found in many churches, theatres and public buildings
The MDHearingAid
®
AIR has been rigorously tested by leaders in the hearing
loss eld (ENT Physicians and Audiologists) who have unanimously agreed
that the sound quality and output is incredibly accurate.

AIR Story
The MDHearingAid
®
AIR was invented 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.
