🔊 "My Hearing Aids Are Whistling": Causes and Common Fixes by Acoustik Hearing Mumbai

It’s a common and frustrating situation: you’re in the middle of a conversation in Mumbai, or enjoying a quiet evening in Thane, and suddenly your hearing aid lets out a sharp, high-pitched whistle. This sound is known as feedback, and while it can be embarrassing, it is usually a sign that something simple needs adjustment.

At Acoustik Hearing And Speech Clinic, the best Hearing and Speech clinic in Mumbai, Navi Mumbai, and Thane, we help patients troubleshoot these issues every day. Here is a guide to understanding why your hearing aids are whistling and how to fix them.

What Causes Hearing Aid Whistling (Feedback)?

Feedback occurs when the sound that is supposed to go into your ear canal escapes and gets picked up by the hearing aid’s microphone again. This creates a "loop" of sound that results in a whistle.

1. Poor Fit or Improper Insertion

The most common cause of whistling is that the hearing aid or the earmold isn't seated correctly in your ear. If there is a gap, sound leaks out.

The Fix: Try removing and re-inserting the device carefully. Ensure it feels snug and secure.

2. Earwax Buildup (Cerumen)

If your ear canal is blocked with wax, the sound produced by the hearing aid hits the wax "wall" and bounces back out of the ear, where the microphone catches it.

The Fix: Have your ears professionally cleaned. At Acoustik Hearing, we provide home visits across Mumbai and Navi Mumbai to check for wax buildup and ensure your ear canal is clear.

3. High Volume Settings

If the volume is turned up too high, the chance of sound leakage increases, leading to whistling.

The Fix: Lower the volume slightly. If you find you need the volume that high to hear, you may need a professional adjustment or a more powerful device.

4. Physical Obstructions

Bringing your hand, a hat, a phone, or even a hug close to your ear can reflect sound back into the microphone.

The Fix: Move the object away from the ear. If your hearing aid whistles every time you use the phone, you might benefit from a device with Bluetooth connectivity for direct streaming.

5. Damage to the Device

A cracked shell in a custom aid or a split in the plastic tubing of a BTE (Behind-the-Ear) model can allow sound to leak.

The Fix: Inspect your device for visible cracks or stiff, yellowed tubing. These parts often need regular replacement.

When to Seek Professional Help

If you’ve checked the fit and cleaned your ears but the whistling persists, it’s time for a professional "tune-up." Your hearing aid may need:

Digital Feedback Cancellation: A software adjustment by an audiologist.
New Earmolds: If you have lost weight or the shape of your ear has changed, a new impression may be required.
