What do Hearing Aids Do?

Hearing aids assist people who experience hearing loss by amplifying sound and delivering clear signals to the brain. These small electronic devices are jam-packed with sophisticated technology, with wireless options and fast processing chips.

Hearing aids mirror the natural process of hearing. They pick up and receive sound, amplify these sounds, and convert them into a clearer signal to be registered by our brains.

Styles of Hearing Aids

All hearing aids consist of the same parts, but the ways they are designed and worn differ depending on the style. Hearing aids consist of a microphone, amplifier, battery unit, processing system, and volume/program control, and ear mold. There are two main categories of hearing aid styles: in-the-ear (ITE) and behind-the-ear (BTE).


ITE hearing aids include full shell and half shell models, which sit on the surface of the ear. There are also more discreet options, such as in-the-canal, completely-in-canal, and invisible-in-canal hearing aids. These are inserted deeper in the ear canal and are not noticeable. ITE hearing aids tend to treat lower levels of hearing loss. While they are discreet, they may be difficult to control if the wearer experiences dexterity issues.


BTE hearing aids consist of two main parts: a plastic case housing electronic components, which is worn over the ear and ear molds which sit within the ear and receive sound. BTE hearing aids are often quite small and are also powerful, treating varying degrees of hearing loss. They may be inconvenient for people who wear eyeglasses.

Receiver-in-canal (RIC) hearing aids are similar to BTE hearing aids in appearance, but differ in that the receiver is situated in the ear canal.
