Most hearing aids have automatic feedback cancellation but there are some instances where feedback (whistling) can occur.Check if your hearing aids are getting covered up
If you are wearing a hat or scarf then make sure that it does not cover up the hearing aids. This also applies if you are leaning your ears against a cushion or pillow. If you are still getting feedback then please look at the other causes listed here or get in contact with us.Check the sound outlet is not blocked
Widex BTE: Check your tips, earmoulds and tubing for blockages. Remove any visible wax with a small brush or cloth. If the wax filter is blocked, then replace this – do not clean it.
Widex ITE: Remove any visible earwax from around the sound outlet with the small brush or cloth. If the wax filter is blocked, then replace this – do not clean it.Check the microphone opening is not blocked
Widex BTE: Use a soft cloth to wipe over the top of the aid and remove any visible wax or debris.
Widex ITE: Open the battery door and turn the hearing aid so the lid is facing downwards. Guide the short wax removing tool through the microphone openings on the door from the inside. If you suspect that earwax or dirt has got into the microphone inside the hearing aids then please contact us - do not insert anything into the microphone.Check your hearing aids are fitted correctly
A poor fit will cause feedback so ensure your hearing aids are fitted correctly. Take the hearing aids out and refit. In the case of ITE hearing aids this is the device itself but with BTE hearing aids this is the tip or earmould. If the hearing aids or tips/earmoulds still do not fit correctly then please contact us.Check your volume level
If this is set too high then feedback can occur so adjust your volume to a lower level. If you are unable to hear at this lower level then it is possible your hearing has changed so please contact us to arrange a free hearing assessment.Have your ears become blocked with wax?
A build-up of wax can cause feedback so if you feel this is the case then please contact us for advice on wax removal.
