For people with mild to moderate hearing loss, a hearing aid can significantly help communication by amplifying sound. Hearing aids are small electronic, battery-operated devices that collect sounds with a microphone and direct the louder signal into the user's ear.
Hearing aids come in a wide variety of types and styles. Some are small and customized to fit into the ear canal. Others are larger and sit behind the ear. An audiologist (a health professional that specializes in hearing) can help determine which hearing aid is best for you or your child.
Depending on the amount of hearing loss, hearing aids may be worn in one ear (monaural) or both ears (binaural). For children who are learning to listen and talk, using hearing aids in both ears is generally recommended.
