If you've encountered an annoying beep in your hearing aids, you're not alone. Although digital hearing aid technology has advanced significantly, and feedback (or acoustic feedback) is no longer as common, it may still occur from time to time.

Feedback happens when the microphone picks up the amplified sound coming from the earpiece, causing that classic beeping sound. This problem can occur for several reasons:

  • Poor Seal: If the mold of a behind-the-ear (BTE) hearing aid doesn't properly seal your ear canal (EAC), or if the shell of a canal-style hearing aid doesn’t fit correctly, a beep is likely to occur.
  • Earwax Buildup: The presence of earwax in the ear canal causes the sound from the hearing aid to bounce back, producing a beep. In this post, we recommend how to clean your ears.
  • Hearing Aid Issues: Sometimes, poor assembly or a defective component, such as an improperly secured earpiece, can cause feedback.
  • Improper Settings: If the hearing aid is operating at a higher power than recommended, this can also be a contributing factor.

How Can I Prevent My Hearing Aids from Beeping?

Clean Your Hearing Aids: Wax buildup and debris can cause feedback. Regularly clean them with a damp cloth or brush, and avoid using cotton.


Check the Tube: For behind-the-ear (BTE) hearing aids, make sure the tube connecting the hearing aid to the mold isn't bent. Straighten the tube, and if the problem persists, consult your audiologist.

Check for Obstructions: If the beeping continues, check for obstructions in the mold.

Adjust the Volume: If the volume is too high, it can cause beeping. Try lowering the volume using the buttons or the app and see if it improves. If it persists, consult your audiologist.

Consult a Professional: If you can't resolve the issue, it's best to consult with your trusted audiologist.

If the sound continues, the mold might be cracked or the tube might have a break. You can separate the mold from the hearing aid and cover the sound outlet elbow: if the feedback stops, the problem is likely with the mold, and it should be checked. If it continues, it’s time to replace the elbow. If the beeping persists after that, it's likely an internal malfunction, and the hearing aid will need to be repaired.

For custom hearing aids, the procedure is similar. If covering the sound outlet doesn't stop the beep, it could be an internal issue.
