Hearing aid feedback is what happens when the acoustic signal—or sound wave—escapes the ear canal and hits the hearing aid microphone. It can sound like a squeal, screech, whistle, loud buzz or hiss. Estes said. If your hearing aid produces static, take it in for a check up. When a hearing aid produces this crackling sound, it usually means it needs service. It could be as simple as a low battery or build up of moisture or dirt. If the feedback is acoustical in nature, there are a few things you can try to fix the problem.
Estes advises, meaning make sure it fits in your ear correctly. Removing excess ear wax opens up the ear canal so sound waves can travel unobstructed to the eardrum. While you're at it, you should also make sure your hearing aids are free of wax and give them a good cleaning. They can check the device to see if there are any mechanical or electronic issues that need to be addressed, make sure the device fits properly and examine your ears to make sure they are clear of obstructions.
In rare cases, you may need different devices, or new earmolds, since ear shapes can change with time, affecting how the hearing aids fit.
