What is hearing aid?

A hearing aid makes sounds louder (amplifies). While hearing aids may amplify some types of sounds more than others, at this time they cannot be made or programmed to amplify only one type of sound, such as a voice. Hearing aids do not restore normal hearing, but they may help people with hearing lose function and communicate more easily.

What should I do if I think I need a hearing aid?

If you think you have a hearing problem and are thinking about getting a hearing aid, see your doctor. If your doctor thinks you may need a hearing aid, another type of specialist (audiologist) can help determine what type of hearing aid will work best for you. The audiologist will pick a hearing aid based on the type and how much hearing loss you have and other factors. He or she can help you learn how to get the most out of your hearing aid. In general, it usually is better to wear hearing aids in both ears, even if the hearing loss in the ears is not equal.

You also need to consider cost. Hearing aids can be expensive, and they are not always covered by insurance. Be sure to ask about a return policy, in case you are not satisfied with the hearing aid, and any warranties.

What are the different types of hearing aids?

Hearing aids differ in how they look, their size, where they are placed in the ear, and how much they can amplify sounds. All hearing aids consist of:

• A microphone, to pick up sound.
• An amplifier, to make the sound louder.
• A speaker, to deliver the sound into the ear.
• Batteries, to power the hearing aid.
