Approximately 28.8 million U.S. adults could benefit from hearing aids. These advanced devices collect and amplify sounds for clearer speech and better background awareness. With all they offer, you want to ensure you’re getting the clearest sound possible.
One issue that can interfere with sound quality is feedback, commonly described as a high-pitched whistling.
Why Does Feedback Happen?

Feedback happens when the sound delivered into the ear by the hearing aid speaker escapes the ear canal. When it escapes the ear canal, the microphone picks up the sound, causing the speaker to whistle or screech. It’s similar to what happens when you hold two phones together during a call.
How Can I Stop Feedback?
There are a few things you can try to stop feedback in its tracks:
- Lower the volume. Extra-loud volume can cause feedback. You may have raised the volume while sitting at a noisy Missoula bar and found that the same level is piercing at a quiet library. Try lowering the volume for a quick feedback fix.
- Check the position. An improperly placed hearing aid can cause feedback. Check that the device is sitting correctly in your ear and try shifting the earmold or dome slightly.
- Clean the hearing aids. Wax and debris can build up on the hearing aid speaker or microphone, leading to feedback. Remove all wax and debris using your hearing aid cleaning kit.
- Check for excess earwax. Earwax is a natural substance the ear canal produces to trap and expel bacteria and debris. In most cases, you don’t need to remove it. However, hearing aids can make you more vulnerable to earwax blockages. If your hearing feels more muffled than usual or you’re dealing with persistent feedback, contact your provider for a safe, professional earwax removal.
- Contact your hearing aid specialist. Long-lasting feedback could indicate a broken part or an issue with the device’s programming. Schedule an appointment with your hearing aid specialist if repositioning and cleaning the devices don’t stop feedback.
