Main causes of whistling hearing aids

  • ill-fitting ear pieces
  • blocked silicone tube
  • device is incorrectly set up
  • blocked ear canal
  • ill-fitting ear pieces
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“. 

Blocked sound tube

When the hearing aid’s sound tube is blocked sound can no longer be transmitted correctly and can produce the annoying whistle sound. Contact your Connect Hearing clinic to have the team review and thoroughly clean the sound tube for you. 

Incorrect settings

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

Blocked ear canal

Whistling sounds can also be caused by things that are not directly attributable to the hearing aid. For instance, the whistling sound may be caused by an earwax plug blocking the ear canal. Please consult your Hearing Specialist to have the ear wax plug removed.


If your hearing aid is producing a whistling sound, don't ignore it. One of the possible solutions is a feedback suppression system that is built into many hearing aids and significantly helps removing annoying whistling sounds.
