Types of Hearing Aid

Hearing aid differ in how they look, their size, where they are placed in the ear, and how much they amplify sounds. Most of hearing aids use digital technology. they are programmed for your needs using a computer. But some hearing aids use analog technology.

Based on where the hearing aids are located, there are 4 types of hearing aid.

 

 

1. Behind the Ear (BTE)
Most parts of the BTE hearing aid are in a case that fits behind ear. The case is connected to a plastic ear mold by a clear tube that wraps around the top of your ear. BTE hearing aids are used for all degrees of hearing loss, especially very severe hearing loss. BTE hearing aids can be made with special features, such as a telecoil that helps with hearing during phone calls and a directional microphone system that can help you hear voices in a noisy room. They may be better for children because of safety and growth reasons.

2. “Mini” BTE (or on-the-ear)
The mini BTE is a smaller version of the BTE hearing aid. The parts are in a case behind the ear, but the case is smaller. And the tube connecting the case to the earpiece is almost invisible. Some mini BTE aids can have a very small earpiece that doesn’t completely fill the ear canal. These ear pieces are less visible than the ear molds used with BTE hearing aids. Also, they reduce the feeling of fullness in the ear and can be more comfortable to wear.

3. In-the-ear (ITE)
The parts of the ITE hearing aid are in a case that fits in the outer part of the ear. It can be used by people who have mild to severe hearing loss. ITE hearing aids can be made with special features, such as a telecoil that improves hearing during phone calls and a directional microphone system that can help you hear voices in a noisy room. Children do not usually use them because the case must be replaced as the child grows.

4. In-the-canal (ITC) and completely-in-the-canal (CIC)
The parts of the ITC and CIC hearing aids are in a case that fits partly or completely into the ear canal. ITC and CIC 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. ITC hearing aids can be made with special features such as a directional microphone system that can help you hear voices in a noisy room. Both ITC and CIC 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. They are not recommended for children.
