Main causes of whistling hearing aids

  • ill-fitting ear pieces
  • blocked silicone tube
  • device is incorrectly set up
  • blocked ear canal
Whistling sounds can be generated when the ear pieces are incorrectly shaped or not well adjusted to the ear canal. The amplified sound coming out of the earmold is picked up again and amplified by the internal microphone which itself generates a sound of increasing intensity until satiation – this is the typical whistling sound that is also referred to as “feedback“. To solve this problem, contact your Connect Hearing hearing care professional to check or replace your earmolds.

Blocked sound tube

When the hearing aid’s sound tube is blocked sound can no longer be transmitted correctly which causes it to produce the annoying whistle. Contact your Connect Hearing clinic to have them thoroughly clean the sound tube or replace it.

Incorrect settings

Whistling sounds can also be generated by incorrect settings of the hearing aid. Your hearing care professional can check whether your hearing aid’s settings are correct or if they need to be adjusted.

Blocked ear canal

Whistling sounds can also be caused by things that are not directly caused by the hearing aid itself. For instance, the whistling sound can be caused by an earwax plug blocking the ear canal. Consult your family doctor or audiologist to have the  ear wax plug removed.


If your hearing aid is producing a whistling sound, it’s important to find a solution instead of just ignoring it. One of the possible solutions is having your hearing care professional activate a feedback suppression system that is built into many hearing aids and significantly helps removing annoying whistling sounds.
