Why does my ReSound ONE whistle and how to stop it?
- CChristine YoungJul 28, 2025
Feedback or whistling can occur for several reasons. Ensure the hearing aid is correctly inserted in your ear; if not, put it back in. Check that the hearing aid is in the correct ear, using the red mark for the right ear and the blue mark for the left ear. If the volume is too loud, try turning it down. Also, make sure you are not holding anything too close to the hearing aid. Check your ear for wax, as excessive wax can cause feedback. Finally, verify that the hearing aid is turned on and charged.
