Troubleshooting behind the ear hearing aids

If you think a hearing aid isn’t working:

  • check it hasn’t been switched to the T setting
  • check that any volume control is set to the correct level
  • check the battery is inserted correctly
  • try inserting a new battery
  • remove the hearing aid and check that the earmould is not blocked
  • check the tubing isn’t twisted, squashed or split
  • check for droplets of condensation in the tubing. Any droplets can be removed by gently pulling the soft tubing off the hooked part of the aid and blowing down it

If you have a body-worn aid, the lead may need to be replaced.


Whistling, squealing, sizzling or buzzing:

  • if the hearing aid is whistling, squealing, sizzling or buzzing this could be feedback, which happens when sound from your hearing aid leaks out and gets picked up by its microphone. Alternatively:
  • you may not have put the earmould in properly – try pushing it gently
  • you may have excess wax in your ears – ask your GP to check
  • check the volume hasn’t been set too high
  • check the aid hasn’t been switched to the T setting
  • contacting your hearing aid centre


You may need to ask your hearing aid centre for help if:

  • the earmould has cracked or does not fit snugly enough
  • the hooked part of the hearing aid has cracked or come loose
  • the tubing has split and you are not able to replace this yourself
