Noises and Whistling in Hearing Aids

Why do hearing aids make noises?

There are plenty of reasons why your hearing aid might whistle or give off feedback. Most of the time, these issues are easy to fix, like a poor fit, too much earwax, high volume, or small problems with the mic or silicone tubing.

How can I stop my hearing aid from whistling?

The most common causes of feedback can usually be resolved with some quick and simple steps. We recommend regular cleaning and maintenance of your hearing aids, as well as periodic check-ups with your doctor or hearing specialist. They can pinpoint the exact cause of the whistling and help eliminate it.

Poor fit of the hearing aid

Sometimes, hearing aids don’t sit properly in the ear. When sound escapes and loops back into the device, it can cause a whistling noise. In this case, finding the right model that fits you better is the best solution.

Too much earwax

Excess earwax can block the sound from traveling through your ear canal. Instead, it bounces back into the hearing aid, causing feedback. A professional ear cleaning by a hearing specialist can solve this.

Hearing aids set at a high volume

If your hearing aids are too loud, the sound can re-enter the microphone and cause feedback. It’s always a good idea to adjust the volume to a comfortable and appropriate level.

Issues with the silicone tubes

If the tube in your hearing aid gets clogged, it won’t transmit sound properly, which can lead to whistling. This can usually be fixed by carefully cleaning the tube or replacing it if necessary.

Problems with the microphone

A loose or displaced microphone can also cause whistling. If you notice something off with your mic, talk to your hearing specialist to get it checked out.
