Whistling Sound

This is also known as feedback is a squealing sound emitted from the hearing aid. According to the NIDCD, a hearing aid may produce a whistling sound from improper fitting or a passageway is clogged. A hearing aid is a mini microphone. We have all experienced the high pitched squeal when an individual speaks too close into a microphone. Here are a few suggestions in troubleshooting a hearing aid that produces unpleasant squealing sounds.


  • Check the hearing aid’s passageway to determine whether the cause of the whistling may be due to debris such as ear wax or moisture, clogging narrow internal canals. Be sure to your device is completely free of earwax and moisture.
  • Inspect the small internal tubing to verify they are attached and intact.
  • Determine whether the volume needs to be adjusted to your hearing comfortability.
  • Double-check that the piece is properly fitted to your ear canal. According to NJ-based audiologist, Karen McQuaide, hearing aids may be worn as a behind-the-ear device or worn in the ear canal.
  • Clothing worn to close too the device may change the signal pathway.
  • Hearing aids have vent holes that are designed to create a more natural sound to your ear. Try plugging the vent to determine if that will reduce the whistling sounds. A displaced microphone could also be the culprit.


  • Do not tap the device against a hard surface in the attempts to readjust the sound. Hearing aids are delicate pieces of equipment with many tiny internal parts. Damage can occur from the rough treatment of the device.
  • Use caution opening the case. An experienced person will not understand how to repair this high-tech piece of equipment.

Distorted or Low Sound

A hearing-impaired individual faces challenges in listening situations. Many times environments are noisy and compete with the sound that the person is focused on hearing. Distortion of the hearing aid amplification only compounds the problem. Here are a few suggestions on how to troubleshoot and possibly improve audibility.

  • Hearing aids come with a wax trapping filter. Check the filter to remove any wax blockages.
  • Check the battery, as it is possible the battery has experienced corruption or has weakened and needs to be replaced.
  • Some Hearing Aid devices come equipped with the telecoil system, also known as t-coil technology. This system was designed to enhance telephone communication by greatly reducing competitive background noises. If the device your using comes with t-coil technology, then a simple switch in settings from t-coil to microphone may fix your distortion issues.
