Why Do My Hearing Aids Whistle? (And How Can I Fix It?)
2 Years Ago
Bengal Rehabilitation Group
A whistling or squealing hearing aid is usually caused by feedback, where amplified sound escapes from your ear and is picked up again by the hearing aid's microphone. Common reasons include an improper fit, earwax buildup, loose earmolds, incorrect insertion, or changes in your hearing. While some causes are easy to fix at home, persistent whistling should be evaluated by an audiologist.
"Why Is My Hearing Aid Suddenly Making That Annoying Whistling Sound?"
You've finally started enjoying clearer conversations with your hearing aids.
Then one day...
"Peeeeeeeeeeee..."
A high-pitched whistling sound starts whenever you hug someone, wear a cap, answer the phone, or even while sitting quietly.
It can be embarrassing in public and frustrating at home.
Many people immediately think:
- "Is my hearing aid broken?"
- "Do I need a new one?"
- "Did I waste my money?"
Fortunately, the answer is usually no.
In most cases, hearing aid whistling is caused by feedback, and it can often be corrected without replacing your hearing aid.
Why Does a Hearing Aid Whistle?
A hearing aid works by:
- Picking up sound through its microphone.
- Processing and amplifying the sound.
- Delivering the sound into your ear.
If some amplified sound leaks back out and reaches the microphone again, the hearing aid repeatedly amplifies the same sound.
This creates the familiar high-pitched whistle, known as acoustic feedback.
Modern hearing aids are designed to minimize feedback, but it can still occur under certain conditions.
