Hearing Aid Basics

How Does a Hearing Aid Work?

The way a hearing aid works is quite simple. First the sound enters the microphone, which converts the acoustic signals into electrical signals. These electrical signals then are transferred over to an amplifier that increases the strength of the signals. After this, the now stronger electrical signals are transformed back into acoustic sound by the receiver (a mini loud speaker). The signal is channeled into the ear canal, either through a small tube or an ear mold. There are three main styles of hearing aids:

In the Ear (ITE) hearing aid

ITE hearing aids fit directly into the external part of the ear. This type of hearing aid is custom made to fit the contours of your ear, to provide the most comfort. The appealing shell styles combine improved cosmetics with optimal power and sound quality.

Behind-the-Ear (BTE) hearing aid

ITE hearing aids fit directly into the external part of the ear. This type of hearing aid is custom made to fit the contours of your ear, to provide the most comfort. The appealing shell styles combine improved cosmetics with optimal power and sound quality. .

Receiver-in-the-Ear (RIE) hearing aid

ITE hearing aids fit directly into the external part of the ear. This type of hearing aid is custom made to fit the contours of your ear, to provide the most comfort. The appealing shell styles combine improved cosmetics with optimal power and sound quality.

With all of the advances in hearing aid technology, more specifically digital technology, hearing aids have dramatically improved over the years. They are now a lot smaller than they have ever been and with far better sound quality. Some of the Top-of-the-line models feature "directional" or "high definition" hearing in their hearing aids. These devices use two microphones and an algorithm to enhance sound coming from the front (the person you are talking to), while tuning down sound coming from behind (background noise).
