Earwax can reflect sound and cause feedback. Do not put cotton buds or tools into your ear. Book a professional earwax and hearing aid fit check.

Whistling / Feedback

Q: Check the earpiece fit

A loose earpiece can let sound escape. Remove the hearing aid gently. Reinsert it using the technique your audiologist showed you. Check for a loose or worn earpiece; ask the clinic to check the fit if needed.

Q: Arrange a tubing replacement

Hard or cracked tubing may leak sound. Check the visible tube for cracks without pulling it. Book a tubing replacement with the clinic.

A hearing aid whistling can happen when amplified sound leaks back into its microphone. A brief whistle as you put it in can be normal, but whistling that continues may mean the earpiece is loose, tubing is worn or your ears need a wax check. These gentle checks can help you find the next step. They are not a diagnosis: if you have pain or a sudden change in hearing, seek medical advice instead.
