In order to ensure optimum working capacity and longevity in your hearing aid, you must perform routine checks on it. Your audiologist will show you the proper ways to do this. Be sure to obtain a battery tester, a drying container, a forced air blower, and a listening tube before starting any of these maintenance examinations.


A whistling sound heard from the hearing aid is called feedback. It occurs when sound comes out of the earmold and reenters the microphone. You should never hear any feedback. If you do, it may mean that the hearing aid is not securely situated in your ear. This can be due to an ill-fitted earmold or from wax buildup in the ear.


Batteries usually last 1 to 2 weeks. To check the strength, use a battery tester. It always a good idea to keep spare batteries on you, making sure they are stored in a cool, dry place. Like all batteries, dispose hearing aid batteries properly.


Regularly clean your hearing aid with a dry, soft cloth. Earmolds should be removed from the device and cleaned separately. If there is any moisture found in the hearing aid, remove the batteries and place the device in a drying container.

Listening checks

Listen to your hearing aid every day using a listening tube. This will guarantee that what you are hearing is clear and not scratchy or weak. If should hear distorted or intermittent sound, examine the tubes for any signs of cracks, holes, or moisture buildup. If there is a crack or hole, contact your audiologist. If moisture is present, use an air blower to dry it. If you hear no sound, check the receiver opening for any blockage from wax or debris. Also, inspect tubing to see if it’s properly connected.
