Whistling (also known as feedback) occurs when amplified sound returns to the microphone and is re-amplified.
If your hearing aid is making a whistling sound, try these troubleshooting tips:
- Most hearing aids whistle when not inserted properly into the ear canal. Try reinserting the tip into your ear canal so it fits better.
- Lower the volume.
- If whistling occurs when raising the volume, you may need more gain and should try our closed ComfortTIP. Please contact customer support.
- Wax or debris can cause whistling. Clean the tubing, tip, and ear canal. Replace the tubing and tip if they appear worn. See information on cleaning and replacing parts.
