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.
