Will My Hearing Aids Whistle or Feel Uncomfortable?

The Quick Answer

"Will my hearing aids whistle or feel uncomfortable? Not if they're fitted properly. Whistling is

just acoustic feedback. It happens when sound leaks out past a poor seal and gets reamplified by the microphone. We solve that by choosing the exact right dome or custom mold for your ear canal geometry to create a comfortable, secure seal. Then I run Real-Ear Measurement to make sure the sound stays where it belongs."

Why Do Hearing Aids Whistle in the First Place?

That annoying high-pitched squeal is called acoustic feedback. It occurs when sound amplified inside your ear canal leaks back out and gets re-captured by the hearing aid's microphone, creating a continuous sound loop.

Common causes of feedback include:

Generic Rubber Domes: Using a standard off-the-shelf dome when your ear anatomy requires a custom-molded fit.
Earwax Buildup: Excess cerumen (earwax) blocks sound waves from reaching your eardrum, bouncing the sound directly back out of your ear canal.
Improper Insertion: The device isn't seated deeply enough or has shifted out of place.
How We Stop Whistling with Real-Ear Measurement (REM)

Whistling should never be something you just "live with." At Valley Mobile Hearing Care, we eliminate feedback through precise physical and digital matching. We evaluate your unique ear canal geometry, fit custom ear molds when necessary, and perform gold-standard Real-Ear Measurement (REM) probe tube testing.

REM measures sound pressure millimeters from your eardrum to ensure amplified sound stays inside your ear where it belongs.
