"The Oticon" Ear Treatment Device
The Oticon was a home treatment device manufactured
by Hearing Devices Corporation of New York during the 1940s. Charles H.
Lehman, who was the president of the company, helped William Demant in
setting up the manufacture of electronic hearing aids in Denmark after
World War II. They both decided to use the name Oticon for Demant’s first
Danish produced hearing aid and this later became the name of the Danish
company, Oticon A/S, which continues today as one of the world’s leading
hearing aid manufacturers.

The Oticon device uses air pressure to gently
massage the ear drum in the belief that this would stimulate the blood
flow in the inner ear and massage the three tiny bones that conduct the
sound vibrations from the tympanic membrane (ear drum) to the oval
window of the cochlea.
You can read the
original instruction brochure, a
copy of which was provided to us courtesy of the Oticon Museum at Eriksholm, Denmark.
