How to troubleshoot common hearing aid problems

Troubleshooting hearing aids involves checking for common issues such as dead batteries, blocked earwax filters, or improper settings. Users should clean the device, ensure it is turned on, and verify volume levels. Persistent problems may require a professional evaluation to diagnose and resolve more complex technical or fitting issues.

If you have hearing loss, hearing aids are the most common and successful treatment for it.  To continue to hear at your best and to keep your hearing aids in optimum performance, it is important to identify, understand, and act when you stumble across hearing aid troubleshooting problems. 

On this page, we go through the issues hearing aid wearers can experience on a day-to-day basis and offer some advice to help you tackle them.

Hearing Aid Troubleshooting: How to fix your hearing aids sound

Troubleshooting hearing aids and fixing Hearing Aids

My hearing aid's sound distorted or muffled

  • Examine your hearing aid batteries, do they look like they have corroded?  If they do replace them with new ones.
  • Examine the battery's small metal prongs that connect with the hearing aid batteries when you close the device door.  Do they look like they have corroded?  Try closing and opening the device door to clean the metal prongs and then replace the batteries with new ones.
  • If you are struggling to clean the metal prongs, your audiologist can do this for you instead.
  • You might have switched the setting to a wireless one, which is generally used when using an assistive listening device.  If so, use a different memory or program.
  • Check for blockages in the tubing or microphone openings, and clean them as recommended by your audiologist.
  • Check the battery voltage.  If the batteries are low, it can affect sound quality. Replace them if necessary.
  • If the above doesn't work at home, your hearing aids might be damaged.  If this is the case, contact your audiologist to book an appointment to look into a repair.

Hearing Aid Problems and troubleshooting hearing aids

My hearing aids are giving me feedback

  • Remove your hearing aids and put them back in, as they might not be in correctly.
  • Turn down your device's volume.  If the feedback continues your audiologist might have to re-fit your hearing aids, as the devices might have too much sound escaping through the vents or ear mold.
  • Your ears might have a build-up of ear wax, as this can cause feedback due to having to turn up the volume or sound bouncing off your wax.
  • If you have lost weight, you might have to have your hearing aids fitted again.  For example, you might have to have new ear molds made to fit your new ear shape.
