Transistor Hearing Aids
These also can be properly called electronic hearing aids. They appeared in a few models in late 1952 and virtually replaced vacuum tube hearing aids by the end of 1953. Transistors need only one battery. Therefore, the reduced size permitted development of a number of types of hearing aids.
| 1) CIC (Completely-In-Canal) | 2) ITC (In-The-Canal) | 3) ITE (In-The-Ear) | 4) BTE (Behind-The-Ear) |
- The body aid, or pocket aid, continued to be popular, especially for those with severe loss, and could now be made smaller than vacuum tube versions.
 |
 |
- Eyeglass hearing aids attained considerable popularity, particularly after Eleanor Roosevelt allowed her name and photograph to be used wearing one.
 |
 |
- Behind-the-ear or over-the-ear models were a huge improvement in cosmetic appeal over body or eyeglass hearing aids and are still the aid of choice for those with severe to profound loss.
Behind-the-ear Hearing Aid
- In-The-Ear models come in several versions: stock or non-custom models, custom concha models, half shell models, and canal aids. The most recent development is the completely-in-the-canal aid. Today, body and eyeglass aids account for less than 1% of hearing aid sales in the United States.
