If you use a hearing device, then you know how important it is to have it in its best condition at all times. After all, it’s what allows you not only to properly hear people around you and enjoy music and sounds from your surroundings. 

However, it’s not uncommon for people to experience problems with their hearing aids – one of which is the squealing or screeching sound that typically occurs when you adjust or remove the aid. 

But why does that happen? Read on as Hear More Associates shares the answer:

Common Causes of Squealing Sounds in Your Hearing Aid


Dust and other substances can easily get inside your hearing aids and block the sound as well as cause squealing noises. If you don’t clean them regularly, dead skin cells and even wax can build up on the membrane of your hearing aid, causing blockages and interfering with your ability to hear properly.

Poor Molding

Another common cause of squealing hearing aid is poor molding. If the mold has too much or too little material or is not correctly attached to its casing, you can experience squealing sounds.

Improper Fit

If you don’t get a perfect fit, you’ll experience squealing noises when the aid moves around. It’s important to remember that not all hearing aids fit every ear perfectly. Your audiologist will do their best to customize them to fit your specific ear, but sometimes problems may still occur.

Mechanical Problems

The squealing sounds can also occur due to mechanical problems in your hearing aid. If the wires are damaged, they can interfere with the sound quality and create squealing noises, or if the microphone or speaker is broken, this can also cause squealing sounds.

How to Solve the Problem

The good news is that there are many ways to fix this problem, and no matter what caused it in the first place, you can probably solve the problem within a few minutes. Here are a few steps you can take to eliminate the problem:

Step 1: Clean your hearing aid.

It’s essential to clean your hearing aid regularly to prevent blockages that can ultimately lead to squealing sounds. Make it a habit to clean them after every time you remove them or before you put them on.

Step 2: Change the battery.

Most hearing aid batteries expire after six months and, after that, can produce squealing sounds when they run out.

Changing the battery is not a difficult task, and most hearing aid companies provide easy instructions on how to do so. Visit your audiologist or look for a do-it-yourself guide online to learn how to change the battery.

Step 3: Check that the wires aren’t damaged.

Make sure to check that the wires that connect the aid to the receiver units are not damaged. Also, check that the receiver units are not broken or damaged and that they are securely attached to the main unit. If there is any damage, you should return them to your audiologist to have them repaired.


It’s important to remember that squealing sounds are always a sign that something is wrong with your hearing aids. If you experience this problem regularly, you should visit your audiologist from Hear More Associates and find out what’s causing it and fix the problem.
