If your Nexus hearing aid is producing feedback or whistling noises, follow these steps to troubleshoot and resolve the issue:
1. Is the Hearing Aid Properly Fitted?
- Feedback often occurs when the hearing aid is not seated securely in your ear.
-
Check the Fit:
- Ensure the ear tip or dome is fully inserted into your ear canal.
- If it feels loose, consider using a different size ear tip or dome for a better seal.
2. Are the Ear Tips or Domes Damaged or Worn?
- Over time, ear tips can wear out, affecting the fit and seal.
-
Inspect for Damage:
- Look for tears, cracks, or wear on the ear tip or dome.
- Replace the ear tip if necessary.
3. Is There Wax or Debris Blockage?
- Wax buildup can cause sound to bounce back, creating feedback.
-
Clean the Device:
- Check the ear tip, sound tube, and microphone ports for blockages.
- Use the cleaning tools provided with your hearing aid to remove wax and debris.
4. Is the Volume Too High?
- High volume settings can amplify sound and cause feedback.
-
Lower the Volume:
- Reduce the volume slightly and check if the whistling stops.
5. Are You Covering the Hearing Aid?
- Covering the hearing aid with your hand, hair, or a hat can cause feedback.
-
Avoid Obstruction:
- Keep objects away from the hearing aid to prevent sound from bouncing back.
6. Is the Hearing Aid Program Correct?
- Certain programs may amplify specific frequencies, increasing the chance of feedback.
-
Switch Programs:
- Use the program button or Ceretone app to switch to a mode like Normal or Outdoor that may reduce feedback.
7. Is the Sound Tube or Receiver Secure?
- A loose or damaged sound tube or receiver can cause sound leakage.
-
Check and Secure:
- Ensure the sound tube is tightly connected to the hearing aid and the ear tip.
- Replace the sound tube if it is cracked or loose.
8. Are You Using the Right Ear Tip Size?
- Ear tips that are too small may not create a proper seal, leading to feedback.
-
Try a Different Size:
- Test larger or custom-molded ear tips to improve the fit.
9. Is the Hearing Aid Damaged?
- Internal damage to the hearing aid can cause persistent feedback.
-
Inspect for Damage:
- Look for visible cracks or loose components.
- Contact your hearing care provider if you suspect internal damage.
10. Have You Tried the Dehumidifier?
- Moisture inside the device can also lead to feedback issues.
-
Dry the Hearing Aid:
- Place it in a hearing aid dehumidifier or a sealed container with silica gel overnight.
