Daily Care for the Hearing Aid

Hearing aids require special care to ensure that they function properly. Your audiologist will show you how to care for and check them regularly. Ask how you can obtain a listening tube, a battery tester, a forced air blower, and a drying container.

Perform listening checks: Listen to the hearing aid every day. Using a listening tube, you can listen to the hearing aids to be sure that they sound clear and not weak or scratchy. Your audiologist will teach you how to listen for intermittency and internal feedback.

Check batteries: Batteries should last about 1 or 2 weeks. Using a battery tester, check that the batteries are at full strength so that the hearing aids are working at peak performance. Always keep spare batteries with you. Store them in a cool, dry place. Discard batteries one at a time. Batteries are toxic, so handle them carefully and dispose of them properly.

Clean the hearing aids regularly with a soft, dry cloth. Check for dirt and grime. Earmolds can be removed from the hearing aids and cleaned with a mild soap solution. Dry them carefully using a forced air blower (not a hair dryer!). Be sure they are dry before reattaching them to the hearing aids.

Minimize moisture in the hearing aids. This is important for proper function. A hearing aid drying container will help keep moisture from building up inside the hearing aids and will lengthen their life. Be sure to take the batteries out of the hearing aid before placing them in the storage containers.

Avoid feedback: Feedback is the whistling sound that can be heard from the hearing aid. It occurs when amplified sound comes out of the earmold and reenters the microphone. You should not be hearing feedback if the hearing aid is securely seated in your ear. Hearing feedback may suggest that the earmold is too small and needs to be replaced or that there is too much earwax in the ear canal.

Talk to your audiologist about what you should do when you start hearing feedback. Turning down the volume of the hearing aid will cut down on the feedback but will also not allow you to hear important sounds.

Regular audiology visits are important for hearing testing, to check the performance of the hearing aid, and to make necessary adjustments.
