Hardware can be susceptible to a lot of technical difficulties, and hearing aids are no exception. These are complicated machinery pieces which sometimes can encounter a number of issues. Hearing aids can get wet, can even start making funny noises while some can completely stop working. Here are some of the problems along with the solutions that hearing aids have been found to encounter:

No sound

Fix: The first step of hearing check is performing a visual inspection of hearing aid. Check the battery compartment door and also the battery installation. Do not forget to double check the battery orientation as it might need to be flipped. Check the battery’s condition from the battery tester. If you do not have a battery tester, replace the battery in your device. This troubleshooting will help you get the correct sound from the hearing aid.

Distorted sound

Fix: This is a common issue with hearing aids. Open the hearing aid’s compartment and remove the battery carefully. Assess the hearing aid for any discoloration or corrosion that has been caused. If there is some issue related to the battery, you need to replace it and test the hearing aid. Make sure that the battery contacts are not bent and the compartment is able to open and close smoothly, without making any scratches on the battery. Look at the hearing aid settings as well. By keeping each adjustment, keep checking the hearing aids to see if the distortion is gone.

Sound is not loud enough

Fix: When you find the hearing aids delivering sound, however, not loud enough, it is about time to start troubleshooting. Check the volume control and make sure it has not been turned completely down. If the volume has been set low, turn the volume up gradually while testing the hearing aid slowly to see if it makes any changes. When the volume control is not the issue, perform a thorough check of the device. Look for any debris or earwax that might be blocking the microphone and clean any particles if on the way. Moisture build-up, small cracks and splits caused on the tubing can be the issue as well.

The device starts to make noises.

Fix: This situation is often called ‘feedback’ and is a result of improperly fitting ear moulds. You need to take this mould out and re-insert it back into the ear. The whistling noise will essentially stop once the device has been appropriately fitted into the ear. You can also try changing the dome size of the hearing aid. When the dome does not form a sung fit in the ear, it can further cause sounds to be leaked into the air making uncomfortable noises. This can also occur from a build-up of wax. Thus, cleaning the device can also act as a solution.


These quick fixes help in solving the problems and deliver some relief. However, if you are still facing issues, it is better to see a hearing professional for better assistance.
