Common Signs Something’s Wrong
- Buzzing or static noise when inserting or removing the aid
- Feedback sound only in one ear
- Whistling during calls or when near objects
- Sound distortion that gets worse over time
What’s Causing the Buzzing or Feedback?
1.
Earwax Buildup in the Mic or Receiver
Wax inside the ear canal or on the aid can reflect sound and create a feedback loop.
2.
Poor Fit or Loose Dome
If your dome or earmold isn’t sealing properly, sound may leak and cause that high-pitched feedback.
3.
Cracked or Worn Tubing (for BTE Aids)
Tiny cracks in the plastic tube can amplify vibrations and cause buzzing.
4.
Microphone Blockage or Damage
Dust or moisture near the mic port may distort sound.
How to Fix It (Or At Least Try These First)
Fix 1:
Clean the Microphone and Receiver
Use a soft brush or wax loop to clean ports. Avoid poking deep—just surface cleaning works.
Fix 2:
Replace or Reseat the Dome
Check that your dome is secure. Try replacing it with a fresh, correctly sized one.
Fix 3:
Inspect Tubing (BTE Models Only)

Hold your tubing up to the light. If you spot a crack or discoloration, it’s time for a replacement.
Fix 4:
Adjust Position or Volume
Move the aid slightly in your ear and reduce the volume. If the sound improves, it was likely mic feedback due to position.
