Body Type Transistor Hearing Aids

Paravox Model K Transistor  Body Hearing Aid

The Paravox Hearing Aid Company of Cleveland, Ohio manufactured the Paravox Model K transistor hearing aid in 1953. It was one of a range of Paravox hearing aids of the time that had a very attractive brushed aluminum case.

The model K had a slightly raised microphone grill on the front and a volume control top center. There were spring pocket clips on either side.

It measured 2⅞” by 1¾” by ⅞” and weighed 3½ oz. with battery.

The Model K hearing aid could be configured for either one or two 1.4 volt RM-1 mercury cells. The hearing aid shown here was configured for only one battery. The battery fit on the bottom left, and a non-removable spacer filled the 2nd battery compartment (bottom right).
