Why Do Hearing Aids Whistle?


Regardless of the amount of money you spend, or the type of hearing aid you buy, at some time 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. Let's take a moment to discuss this further. 

Why Does Whistling Occur?

Technically speaking, the whistling sound is known as feedback. It is the result of the sound that leaves your hearing aid finding its way back into your hearing aid microphone. At that point, the sounds are amplified again, which causes the irritating whistling sound. Some of the more common instances in which whistling may occur are when your ear is covered or you are removing or inserting your hearing aid.

What is the Source of the Whistling?

Most digital hearing aids come with a built-in feature to cancel or diminish feedback. At times, even this feature can occasionally 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 include excessive earwax build-up, cracked or broken tubing, excessive volume at specific frequencies, or having a poor-fitting aid.
