Why Are My Hearing Aids Whistling?


There are few things as annoying as hearing aids that won’t stop whistling. This feedback is caused when sounds escape from your ear, circle back, and enter the hearing aid’s microphone. When this happens, the sound is re-amplified through your ear and causes a whistling sound. This feedback can be annoying to you and the people around it, making it difficult for you to hear or adequately communicate.

If you’re experiencing feedback from your hearing aids, don’t fret. There are a few steps you can take to prevent your hearing aids from whistling before you opt to replace your hearing aids altogether.

5 Reasons your hearing aids are whistling

To prevent your hearing aids from whistling, you need to determine the root cause of the problem. Here are five reasons why your hearing aids are creating annoying feedback.

1. Improperly fitted

Feedback happens when noise escapes your eat and re-enters the microphone of your hearing aids. If your hearing aids aren’t fitted to your ear correctly, the sound will leak out from the gap and cause a feedback problem.

If you don’t have custom earmolds for your hearing aids, you might want to invest in those to cut back on the chance of feedback. If you have custom earmolds and are experiencing whistling, you should have them refit, so the sound cannot escape your ear.

2. Inserted incorrectly

Even if your hearing aid is custom fit for you, it can still cause feedback if inserted incorrectly. If the onset of feedback from the device is sudden, try removing the hearing air and reinserting it properly.

More often than not, this will help resolve the issue.

3. Wax buildup

Wax production is a normal function of the body. But if too much wax builds up in your ear cavity, it can cause feedback from hearing devices. When the sound is amplified from the hearing aid into the ear cavity, it has nowhere to go and is blocked by the wax. This causes the sound to leave the ear and re-enter the microphone of the device.

Regularly cleaning your ears can help prevent this from happening, but if there is too much wax buildup, you will need to visit a professional to have it removed.

4. Microphone blockage

Another reason you might be experiencing whistling from your hearing aids is if the microphone is blocked. Most commonly, the microphone would be blocked by earwax. However, it can become blocked by debris and dirt as well.

When the microphone becomes blocked, the hearing airs will give off feedback. The individual can usually resolve this by removing whatever is causing the blockage.

5. Needs repairs

Sometimes, there isn’t an outside factor causing the feedback, and the problem is with the hearing aid itself. Because hearing aids are small and delicate, they aren’t immune to damage. Normal wear and tear or mishandling of the device can misshapen or bend critical elements needed to amplify sound properly.

If none of the other reasons mentioned above seem to be the problem, there is a good chance you will need to visit your audiologist to repair your hearing aids.
