Dr. Cherukuri worked with world-class Doctors of Audiology and Audiologists
to create the MDHearingAid®PRO to their exact technical specications, so

that the range of sounds associated with the human voice would be amplied,

without overly amplifying background sounds.

The MDHearingAid®PRO 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.

The MDHearingAid® Story

The MDHearingAid®PRO was developed by a board-certied Ear,
Nose and Throat physician in Chicago, IL, Dr. Cherukuri. He
encountered patients in his daily practice who would benet 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 ampliers, including
those seen on television. He found almost all of these devices only

amplied 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.

Fitting and Assembly

Step 1: Select the Correct
Ear Dome Size

Your MDHearingAid®PRO comes with

clear Traditional Tubing and ve different
sized silicone Ear Domes to t most

adult ears. Test the Ear Dome size by
attaching Ear Dome to Tubing before
inserting into ear canal.

Attach Ear Dome to Tubing

a) Hold the Elbow of the Tubing with

one hand and hold the ‘mushroom’
top of the Ear Dome with the other hand.

b) Push the Ear Dome over the ridges
on the end of the Elbow.

c) Pull lightly in the reverse direction
to make sure the Ear Dome is
attached securely.

Insert Ear Dome in Ear Canal

Hold the Elbow of the Tubing (with Ear Dome attached) and insert
Ear Dome into the ear canal. The Ear Dome should nestle in the ear
canal without force (similar to placing a sink stopper into a sink).
The ‘mushroom’ top of the Ear Dome should be in the ear canal
and not protrude into the outer bowl of the ear.

Test Ear Dome for Fit

• Turn head side to side and simulate chewing.
If the Ear Dome pops out, it is too big.

• Nod head towards the ground. If the Ear
Dome slips out easily, it is too small.

When the Ear Dome is too small, there is
space between the Ear Dome and the ear
canal, and you may hear whistling when the
Hearing Aid is on.

Repeat the steps above with different sized

Step 2: Cut Tubing Length

a) Place the Hearing Aid Body

behind the ear so the Earhook
rests comfortably on top of the

ear (in front of any eye wear).

b) Insert Ear Dome, with Tubing
attached, into ear canal, and
align Tubing next to Earhook.

c) Use a pen and mark a line
on the Tubing ABOVE the
bottom of the Earhook tip.
Cut Tubing at marked line.

Step 3: Attach Tubing
to Earhook

Using your thumb and rst nger, hold
the Tubing up to the Earhook tip, and
twist back and forth until the Tubing
slides OVER the Earhook tip.

Make sure the ‘mushroom’ portion of the
Ear Dome points into the ear canal.

‘Measure twice, cut once!’

Please note: This length will vary.
Tubing must be measured and cut
separately for each of your ears.
