If your hearing aids are making a high-pitched whistling sound, you’re not alone. This sound—called feedback—happens when amplified sound escapes your ear and gets picked up again by the hearing aid microphone. The good news? It’s usually an easy fix.
Common Causes of Hearing Aid Whistling
1. Poor Fit
If your hearing aid or earmold isn’t sitting properly in your ear, sound can leak out and cause feedback. This can happen if the device shifts when you talk, chew, or smile.
2. Earwax Buildup
Excess wax can block sound from traveling properly through the ear canal, causing it to bounce back into the microphone.
3. Loose or Damaged Tubing/Receivers
Over time, tubing can harden or crack, and receivers can weaken—both of which can lead to whistling.
4. Volume Set Too High
Turning the volume up too far can increase the chance of feedback.
5. Changes in Your Hearing
If your hearing has changed, your hearing aids may need reprogramming to match your current needs.
How to Fix It
Make sure your hearing aids are inserted correctly.
Clean your devices regularly and check for wax buildup.
Lower the volume slightly to see if the sound stops.
Replace wax guards or filters if needed.
Schedule a quick check with our office for adjustments or repairs.
Modern hearing aids have built-in feedback management systems, but even the best technology needs proper fit and maintenance to work its best.
