Why Are My Hearing Aids Whistling? Causes & Quick Fixes You Can Try at Home

If you’ve ever heard a high-pitched squealing or whistling sound from your hearing aids, you’re not alone. This is called feedback, and while it can be frustrating, it’s usually something simple that can be fixed—often right at home.

Here’s what you need to know about why it happens and what you can do when your provider isn’t immediately available.

Feedback occurs when sound that’s already been amplified by your hearing aid escapes your ear and gets picked up again by the microphone. This creates a loop—resulting in that familiar whistling noise.

Common Causes of Feedback

• Poor Fit or Placement
  If your hearing aid or earmold isn’t seated properly, sound can leak out.

• Earwax Buildup
  Excess wax can block sound from traveling correctly, causing it to bounce back.

• Volume Too High
  Turning the volume up too much can increase the chance of feedback.

• Loose or Damaged Tubing
  For behind-the-ear devices, tubing that is cracked or loose can cause sound leakage.

• Objects Near the Ear
  Things like hats, masks, phones, or even hugging someone can trigger feedback.

Quick Fixes You Can Try at Home

Before worrying, try these simple steps:

1. Reinsert Your Hearing Aid
Take it out and place it back in carefully. A snug, proper fit often solves the issue.

2. Check for Earwax
If you suspect buildup, avoid using cotton swabs. Instead contact us for safe cleaning.

3. Lower the Volume
If your device allows manual control, try reducing the volume slightly.

4. Inspect the Device
Look for cracks in tubing, loose parts, or debris in the microphone or speaker.

5. Remove Nearby Obstructions
Adjust hats, glasses, or anything that might be pressing against your hearing aid.

If you’ve tried the steps above and are still experiencing feedback, it may be time for a professional adjustment. Your hearing aids might need:

• A better dome fit or new earmold
• Maintenance or repair
