How to do a hearing aid check

Hearing aids are electronic devices and sometimes they will breakdown. The sooner you discover problems, the quicker they can be fixed. Here’s how to keep your hearing aid in top condition.

Headphones or speakers with a dodgy wire make for an irritating listening experience. But when a sound malfunction is in the devices you use to hear everything, it’s downright frustrating. If there is a fault with your hearing aid, contact us to borrow one while it’s repaired.

Here’s how you can keep your hearing aid in top condition.

Quick check

If something doesn’t sound right but you’re pressed for time, this quick check helps identify some of the most common problems.

  1. Turn the aid on, cup it in your hand, and listen for whistling sound. If you hear one, you know it’s producing sound. If it’s not working, check the battery (see tips below). Also examine the sound hole or ear mould for wax build up and, if your aid has tubes, check for moisture in the tubing. 

  2. Ensure the battery door is closed securely and (if applicable) the tubing is securely on the ear hook and glued to the mould.

Physical check

When you’ve got more time, a regular, thorough check will keep your hearing aid in tip-top shape and identify any malfunctions before they cause you problems.

Here’s what to look for:

Ear mould (for behind-the-ear aids only)

  1. If there’s a wax build-up: clear it using a wax tool, ask your local Hearing Australia centre for information about available products to assist.

  2. If the ear mould is dirty: wipe it with a tissue or damp cloth. If that doesn’t do the trick, detach mould from the hearing aid and wash it with warm, soapy water. Shake the mould to remove water from tubing and if you have an air puffer, blow air through the tubing and then leave the mould to dry overnight.

  3. If there’s moisture in the tubing: pull mould tubing off the earhook and use a puffer to blow air through the tubing. The bend where the tubing goes into the ear mould is particularly prone for moisture build-up.

  4. If the tubing is kinked or twisted take the mould to Hearing Australia to get new tubing as it affects the passage of sound to the ear.

  5. If there are holes or splits in the tubing: Take the ear mould to Hearing Australia for repair or to arrange a new tube as they will cause whistling and affect the sound.

Hearing aid

  1. If there are cracks in the case: Take it to Hearing Australia for repair as the electronic components might get damaged.

  2. If it’s not quite right: check each aid is attached to the correct ear mould. BTE aids usually have a red marker for the right ear blue for the left. They’re often located in the battery compartment.


  1. If the battery is leaking or corroded: throw away leaking battery, clean away corrosion, which looks like white power, on battery contacts and compartment with a cotton bud dipped in methylated spirits. If it’s too damaged, take the aid to Hearing Australia for repair.

  2. If it’s not quite right: check the battery in a battery tester and change if it is low. Battery testers can be purchased in Hearing Australia centres. You can also check to see if the battery is expired via the expiration date on the back of the battery package. If in doubt, try changing your battery for a new one.

    Important information about batteries:

  • WARNING: Keep batteries in a safe and secure location out of reach of children.
  • Swallowing may lead to serious injury in as little as 2 hours or death.
  • Examine devices to ensure the battery compartment is secured. If the compartment is not secure, do not use and bring in to your Hearing Centre for checking.
  • Children like to copy, so do not change batteries near them.
  • Dispose of batteries appropriately – ensure that they cannot be accessed by children, and keep away from flames.
  • Do not attempt to recharge batteries unless you have been given rechargeable-only batteries.
  • Special battery safety measures are required for hearing aids fitted to children under 5 years of age, and battery safety features can be requested for aided children with young siblings or adults at risk of incorrect use.
  • Please ensure that you follow the audiologist’s safety recommendations at all times.
  • If you experience an incident related to battery safety please report this to Hearing Australia.

Other tips

  1. Use a dry aid kit: Storing the aids in a dehumidifier dries them out, reducing the number of repairs. This is especially important in a humid environment or if you’re prone to perspiration. You can speak to your local Australian Hearing centre to learn more about dry aid kit options.

  2. Keep Them Dry: Unless you have special water-resistant aids, remove before bathing or swimming.
