Understanding why hearing aids whistle
If you notice a whistling sound in your hearing aids, you’re definitely not alone. It’s known as hearing aid feedback, and it’s a high-pitched noise that can occur when sound that should go into your ear canal is detected by the microphone of your hearing aids and gets amplified.1
This is different from tinnitus, where you hear a high-pitched noise coming from inside your ear. Hearing aid feedback is common and often easy to fix. Here are seven possible reasons for whistling and what you can do about it.
How to stop hearing aid feedback
If you’re new to wearing hearing aids, or you’ve switched to a new style, rest assured that a period of adjustment is completely normal. Still, it’s important to check that your device is properly inserted.
"If your hearing aids aren't fitting just right, sound can get out and be picked up again through the microphones, which leads to a whistling sound," explains Durrheim.
"You may need a different dome or even a customer earmould for a better seal and to help prevent feedback," Durrheim says. "Switching to a better fitting option often solves the problem."
