Danavox (Aditone) Model 583 "Thumbalina" Transistor Hearing Aid
The Danavox (Aditone) Model 583 "Thumbalina" transistor body hearing
aid was made by Danavox International A/S of Copenhagen, Denmark in
1960. It was sold under the "Aditone" trade name in Germany.
It was a tiny body (or barrette) hearing aid for its day. In
fact, it was so much smaller than all the other hearing aids of the time
that it was named "Thumbalina" from Hans Christian Andersen's story of
Thumbalina, a tiny girl who was so small she was only half the size of a
thumb.
This hearing aid measured 1 15/16" x 15/16" x ˝" (4.9 x 2.4 x
1.2 cm) and weighed (including battery, ear mold, receiver and cord)
just 1.3 oz. (36 g).
