You can wear hearing aids behind the ear, in the outer ear, or in the ear canal. Most newer models fit in the ear or ear canal.

• All parts of a behind-the-ear (BTE) hearing aid are found in a case that fits behind the ear. The case is connected to a plastic ear mold that fits inside the outer ear. BTE hearing aids are used for all degrees of hearing loss, especially very severe hearing loss. They may be better for children because of safety and growth reasons. Poorly fitting BTE ear molds or a buildup of earwax may cause a whistling sound (feedback).
• All parts of an in-the-ear (ITE) hearing aid are found in a case that fits in the outer part of the ear. It can be used by people with mild to severe hearing loss. ITE hearing aids can be used with other hearing devices, such as a telecoil that improves hearing during phone calls. ITE hearing aids can be damaged by earwax and fluid draining from the ear, and their small size may be difficult for some people to handle. Children do not usually use them because the case must be replaced as the child grows.
• All parts of an in-the-canal (ITC) hearing aid are found in a case that fits partly or completely into the ear canal. ITC hearing aids are used by people with mild to moderate hearing loss. They are made to fit the shape and the size of your ear canal. They can be damaged by earwax and fluid draining from the ear, and their small size may be difficult for some people to handle. They are not recommended for children.
