If the hearing device has no sound, the battery may be worn out, the sound outlet may be clogged, or the microphone opening may be clogged, notes Oticon. Clean the sound outlet, or change the wax filter if it is clogged. If the microphone opening is clogged, clean it with a brush. If none of the solutions work, replace the battery.

If a whistling or howling sound is heard when the device is inserted, there is a problem with earwax, or the hearing device is inserted improperly, explains Oticon. First remove and reinsert the hearing aid following the proper instructions. If the whistling or howling sound is still there, go to a doctor to look at problems with the ear canal, such as excess earwax.

If a distorted sound is heard, the problem may be due to the battery contacts, the battery itself or hearing aid settings, according to Oticon. To fix problems with the battery contacts, which may be dirty or corroded, open and close the battery compartment several times. To fix problems with the battery, clean battery surfaces with a dry cloth, or replace the battery if cleaning it doesn't fix the problem. Finally, make sure that the hearing aid is switched to the microphone signal and not telecoil.
