Why Do Hearing Aids Whistle?

Regardless of the amount of money you spend or the type of hearing aid you buy, at sometime you will face a whistling noise while wearing them. Occasionally the sound is perfectly normal and not worthy of concern. Other times it can be a sign that something is wrong or that your hearing aid is not adjusted properly.

Technically speaking the whistling sound is known as feedback. It is the result of sound that leaves your hearing aid but finds its way back into your hearing aid microphone. At that point the sounds is amplified again causing the irritating whistling sound. Some of the more common ways for it to occur are when your ear is covered or you are removing or inserting your hearing aid.

Most digital hearing aids come with a built-in feature to cancel or diminish feedback. At times even this feature can occasional fail allowing some feedback to occur. If you are experiencing frequent feedback there could be a greater issue at work. If removing and reinserting the hearing aid does not resolve the issue there are a couple of other likely causes. Some of these causes in include excessive earwax build-up, cracked or broken tubing, excessive volume at specific frequencies, or having a poor fitting aid.
