3, Common BTE Hearing Aid Problems
If there is whistling, squealing, sizzling or buzzing, this could be feedback which happens when sound from your hearing leaks out and gets picked up by the hearing aid microphone. If there is whistling happening, you may not have the hearing aid in properly. You can take it out and put it in again, trying to ensure that the mould, or the thin tube and rubber dome is correctly positioned in your ear and pushed firmly and snugly into your ear. Another reason that you might have whistling or feedback in the hearing aid is that you have excess wax in your ears. This causes the sound to go in to your ear, and bounce off the wax, causing the feedback.
If none of these work, book an appointment to see your audiologist as the hearing aid may be faulty or you may need a new mould or a new thin tube.If the hearing aid isn’t working, check that the ear mould or tube is not blocked and the tubing is not twisted, squashed or split.Check that the battery is in the right way round in the hearing aid or even try a new battery, as batteries can occasionally be faulty.
If the hearing aid is still not working, check whether there are any droplets of condensation in the tubing.
Hearing aids, naturally, are exposed to moisture from your skin as well as the air which can cause a static sound in the hearing aid or cause the hearing aid to turn on and off by itself. Keeping hearing aids dry will result in the hearing aid lasting longer. If you have a problem with your hearing aid then you should contact your audiology department.
You should also arrange a hearing aid service with your audiologist every 6 months to ensure that the hearing aid is well maintained.
