Hearing Aids Overview

Hearing aids are incredibly sophisticated and powerful electronic devices. They were developed throughout the 20th century and are currently in an exciting time of innovation and design. Hearing aids are used to amplify sound and provide a clearer sound signal to be registered by the brain. With hearing loss, signals may become muddled and speech recognition may suffer. Hearing aids essentially replicate the natural hearing process, by picking up sounds, amplifying them, and then sending a cleared up signal to the brain to be processed as sounds we recognize.

Hearing Aid Styles

There are several hearing aid styles, to meet both the diverse configurations of hearing loss and personal aesthetic requirements.


Behind-the-ear hearing aids are quite discreet, and treat a wide range of degrees of hearing loss. BTE hearing aids have their electronic components housed in a plastic casing that sits on the back of your ear, while a plastic tubing that delivers amplified sound connects the pieces to a mold that rests in your canal. Receiver-in-canal hearing aids look like BTE hearing aids; they differ in that the receiver rests in your ear canal.


In-the-ear hearing aids come in many different forms. You may recognize the ones that sit on the surface of the ear, whether in a full or half shell.

Other ITE hearing aids include invisible-in-canal or completely-in-canal, where the entire hearing aid is inserted and rests inside the canal.
