Eyeglass Style Transistor Hearing Aids: 1954-1990

Beltone "Tempo" Eyeglass Hearing Aid

The Beltone "Tempo" eyeglass hearing aid was made by Beltone Electronics Corporation of Chicago, IL in 1967.

All the electronics were housed in one temple piece. Thus, these eyeglass hearing aids could be configured for one ear, or both ears. In these pictures there is a hearing aid only in the right temple piece.

The Beltone "Tempo" used an integrated circuit for its amplifier.
