Why Do Hearing Aids Whistle?
Feedback occurs when amplified sound leaks out of the ear canal and is picked up by the hearing aid's microphone again, creating a loop of amplification that produces a high-pitched whistle.
Loose fit — the hearing aid or ear mold is not seating properly in the ear
Earwax buildup — wax reflects sound back toward the microphone
Cracked or worn tubing — sound leaks through damaged tubes
Volume too high — excessive amplification increases feedback risk
Jaw movement — chewing or yawning temporarily changes ear canal shape
Hugging or placing phone near ear — objects reflect sound back
How to Fix Hearing Aid Whistling
Check the fit: Ensure the hearing aid/dome is properly seated in your ear. Re-insert it carefully.
Clean earwax: Remove earwax from the hearing aid and your ear canal. Replace wax guards.
Check tubing: Inspect BTE tubes for cracks, hardening, or disconnection. Replace if damaged.
Lower volume: If volume was recently increased, try reducing slightly.
Visit your audiologist: If home fixes do not work, professional adjustment or a new ear mold may be needed.
When to Seek Professional Help
Feedback persists after cleaning and reinsertion
Feedback is new — device did not whistle before
Feedback occurs even at low volume
You suspect the ear mold no longer fits properly
Tubing appears damaged or discolored

Daily Hearing Aid Care Routine
Morning: Wipe hearing aids with a soft dry cloth before inserting. Check for visible wax or debris in the sound outlet.
During the day: Avoid exposing hearing aids to extreme heat, water, or hairspray. Remove before showering or swimming.
Evening: Remove hearing aids, open battery door (or place in charger for rechargeable). Wipe clean and place in dehumidifier box overnight.
Weekly: Clean wax guard/filter. Use the cleaning brush provided with your hearing aid to clear microphone and receiver ports.
Every 3-6 months: Visit Professional Hearing Solutions for professional deep cleaning, tube replacement, and performance check.
When to Seek Professional Help
Sound quality has changed significantly despite cleaning and fresh batteries
Physical damage visible (cracked casing, broken tube, missing parts)
Persistent feedback or whistling that reinsertion does not fix
Hearing aid falls out frequently — may need new ear mould or refitting
Your hearing has changed — an updated audiogram and reprogramming may be needed

Frequently Asked Questions
Q1: Is occasional whistling normal?
Brief feedback when inserting or removing the hearing aid, or when something gets close to your ear (phone, hand) is normal. Constant whistling is not — seek adjustment.

Yes. Earwax buildup is one of the most common causes. Regular wax guard replacement and ear cleaning help prevent it.
