Transistor Ear-Level Hearing Aids—General
Information
The development of transistors allowed for the miniaturization of
hearing aids because transistors were much smaller than vacuum tubes and
didn't require 2 high-powered batteries to run them.
Thus, only 3 years after the first completely transistorized body aid
came out, manufacturers had found ways to shrink the hearing aid down
into a behind-the-ear model.
In the following years further miniaturization led to in-the-ear aids
(ITE), then even smaller in-the-canal aids (ITC) and finally tiny
completely-in-the-canal (CIC) hearing aids.
The 3 classes of ear level hearing aids in the museum
are:
- Behind-the-ear (BTE) hearing aids
- Eyeglass style hearing aids
- In-the-ear (ITE) aids including In-the-canal (ITC) and
Completely-in-the-canal (CIC) hearing aids as well
You can gain an overview of each of these classes by clicking on the links to
them below.
