TROUBLE SHOOTING HEARING AIDS
First and foremost if there is a problem with your hearing aid, perform a ‘Listening Check’ Listen for:
- No output
- Muffled Output
- Feedback (whistling sound)
- Distortion
- Intermittent Sound
If there is no output from hearing aid
Battery
- Is battery dead? Or corroded? Or Leaked?
- Replace a fresh battery and try again.
- Make sure that positive and negative terminal of battery are in proper position in the battery compartment. The positive side of the battery should face upwards.
- Check for corrosion on battery compartment. This can be removed with a pencil eraser.
- For Rechargeable aids, check charging point-socket is clean, without dirt or moisture. Keep for charging and try back on after aids are completely charged.
Earmoulds
- Check to see that earmould is not impacted with wax.
- The earmould may be washed with warm soapy water.
- Be sure that earmould is completely dry before putting it back in the ear.
Wax Guard block
- Check to see that dome is not impacted with wax.
- Remove the dome, clean the pores and replace a new waxguard.
Moisture
- Check for moisture. Wipe the aid, dry it completely.
- If the hearing aid is wet, place aid in dry aid box.
If there is muffled output from hearing aids
- Check for dirty or clogged microphone screen
- Earmould/ Dome almost completely clogged with wax
- Nearly exhausted battery
- If internal defects are suspected, consult audiologist
If there is feedback output from hearing aids after wearing your hearing aids:
- Volume control setting is too high
- Improper fitting of earmould/dome
- Crack in tubing
- Feedback cancellation is not done properly
If there is distorted output from hearing aids
- Distortion can be characterized as sounding scratchy, having static, weak volume or a “motor-boating” effect.
- Check for corrosion on battery contacts and terminals
- Check for covered or clogged microphone opening
- Excessive wax in ear in wearer’s ear
- Earmould/ dome needs venting
If there is intermittent output from hearing aids
- May be characterized by scratchy sound or hearing aid sounding like it is going on and off
- Check for corrosion on battery contacts and terminals
- Make sure battery is correctly seated and snug in battery compartment
- Feedback cancellation is not done properly
- Make sure tubing does not collapse or bend when head is turned
- Defective volume control
- If internal problems are suspected, consult an audiologist
