binaural hearing aids

Hearing aids require care to ensure that they work properly.  If you notice a problem, here are a few tips on how to troubleshoot problems with your hearing aid.

THE HEARING AID APPEARS TO BE DEAD OR WEAK

Reason #1

  • Cause: Dead, weak, or wrong type of battery.
  • Test: Substitute new battery.
  • Remedy: Battery replaced.

Reason #2

  • Cause: Battery reversed in battery compartment so that the (+) terminal is where the (–) terminal should be.
  • Test: Take the battery out, turn it over and re-insert the battery.
  • Remedy: Battery inserted correctly.

Reason #3

  • Cause: The earmold is plugged with wax or water.  Detach the earmold (behind the ear hearing aid only), from the hearing aid to perform the next step.
  • Test: Blow through the earmold to see if there is air passage.
  • Remedy: Use water and/or air pressure to clean the earmold tubing.

Reason #4

  • Cause: On/Off switch is in the OFF position or Mic-Telephone switch is in the Telephone (telecoil) position.
  • Test: Examine the switch.
  • Remedy: Switch placed in the correct position.

Reason #5

  • Cause: Blocked receiver port (where the sound comes out).
  • Test: Examine
  • Remedy: Replace the wax guard and/or brush over receiver port.

Reason #6

  • Cause: Blocked microphone port.
  • Test: Examine; may hear a shushing noise but no amplified sound.
  • Remedy: Replace microphone screen and/or brush over mic port

THE HEARING AID WORKS INTERMITTENTLY OR FADES

  • Cause: All of the above, plus the tubing has collapsed (again this only applies to behind the ear hearing aids).
  • Test: Examine tubing for crimping.
  • Remedy: Have tubing replaced.

THE HEARING AID WHISTLES OR SQUEALS

Reason #1

  • Cause: Earmold/aid too small or not properly seated in the ear
  • Test: Push earmold/aid firmly in ear to see if feedback ceases.
  • Remedy: Replace earmold or have aid re-cased.

Reason #2

  • Cause: Crack in tubing or air leak between earmold and tone hook.
  • Test: Remove earmold and see if feedback ceases if finger is placed over the sound outlet (end of the tone hook).
  • Remedy: Have tubing replaced.

Reason #3

  • Cause: Crack in tone hook
  • Test: Remove earmold and see if feedback continues even if your finger is placed over the end of the tone hook.
  • Remedy: Have tone hook replaced.

Reason #4

  • Cause: Volume control/gain is turned up too high for type of earmold or style of hearing aid.
  • Test: Reduce volume to see if feedback disappears at a lower level.
  • Remedy: Turn down volume or see the audiologist to have the aid re-programmed or vent size adjusted.

Reason #5

  • Cause: Excessive ear wax in the ear canal.
  • Test: Otoscopic inspection by hearing healthcare provider.
  • Remedy: Have your earwax removed.

THE SOUND IS DISTORTED

Reason #1

  • Cause: Dirty or corroded battery
  • Test: Wipe surfaces of the battery with a clean cloth
  • Remedy: Battery replaced.

Reason #2

  • Cause: Hearing aid switched to telecoil
  • Test:  Examine switch
  • Remedy: Place switch in the correct position.
