Hearing Aid Whistling (Feedback)

What is Hearing Aid Whistling (Feedback)?

Hearing aid whistling, also known as feedback, is a high-pitched squealing or whistling sound that occurs when sound from the hearing aid's speaker is picked up by its microphone and re-amplified. This creates a loop that results in the unwanted noise. While feedback can sometimes be caused by improper hearing aid fit or settings, excessive earwax buildup is a common and often overlooked cause.

Types of Hearing Aid Feedback

Acoustic Feedback – Occurs when amplified sound leaks from the ear canal and re-enters the hearing aid microphone.
Mechanical Feedback – Caused by vibrations within the hearing aid components.
Electronic Feedback – Results from internal malfunctions in the hearing aid's circuitry.

Symptoms of Hearing Aid Whistling

A persistent high-pitched whistling or squealing sound
Feedback noise occurring when inserting or adjusting the hearing aid
Sound distortion, making it difficult to hear clearly
The whistling stops when removing or adjusting the hearing aid

Causes of Hearing Aid Whistling

Poorly fitted or loose hearing aids
Blocked or damaged hearing aid tubing
Volume set too high, causing sound to escape and be re-amplified
Earwax buildup blocking the ear canal, preventing proper sound transmission
Feedback settings not properly adjusted on digital hearing aids

How Earwax May Cause This

When excessive earwax builds up, it can prevent sound from traveling effectively through the ear canal. The trapped sound may bounce back into the hearing aid microphone, leading to constant whistling or feedback noise. Additionally, earwax can block the hearing aid’s receiver or vent, further increasing the likelihood of feedback and reducing sound clarity.
