If your hearing aid is whistling, it’s likely due to feedback, which occurs when amplified sound from the hearing aid speaker leaks out and re-enters the microphone, creating a high-pitched squealing or whistling sound. Here are some common causes and potential solutions:
Causes and Fixes for Hearing Aid Whistling
Poor Fit or Loose Earmold
Cause: If the hearing aid isn’t fitting snugly, sound may escape and loop back, causing feedback. This often happens if the mold has loosened due to earwax buildup or changes in ear shape over time.
Fix: Adjust or replace the earmold. You might also try gently repositioning the hearing aid in your ear to improve the fit.
Earwax Buildup (Cerumen)
Cause: Excess earwax can block the ear canal, causing sound to bounce back and trigger feedback.
Fix: Have your ears cleaned by a professional. Avoid using cotton swabs, as they can push wax deeper.
Volume Set Too High
Cause: Turning up the volume too high may amplify sounds to the point where they leak out and cause whistling.
Fix: Lower the volume and check if the feedback stops. If you still struggle to hear, consult your audiologist to reassess your hearing aid settings.
Malfunction or Damage
Cause: A cracked earmold, tubing, or casing could allow sound to leak out.
Fix: Inspect your hearing aid for visible damage and replace any faulty parts.
Hearing Aid Positioning
Cause: Improper insertion can prevent a proper seal, allowing sound to escape.
Fix: Ensure the hearing aid is correctly positioned according to your audiologist’s instructions.
Changes in Hearing Needs
Cause: If your hearing has changed, your current settings may no longer suit your hearing loss level, leading to feedback.
Fix: Schedule a hearing test and adjustment appointment with your audiologist.
Acoustic Leakage from Thin Tubing
Cause: In hearing aids with thin tubing, wear, and tear or blockage can cause feedback.
Fix: Replace the tubing if it is damaged or blocked.
If the whistling persists after trying these solutions, it may be time to visit your audiologist for further evaluation and possibly a more customized hearing aid solution.
