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).
