Auricles

Celluloid Auricles 1

This is the largest pair of auricles in the museum. They are made of a beautiful reddish brown celluloid resembling tortoiseshell. The material is generally referred to as "Faux Tortoiseshell."

They are unmarked as to maker, but I believe they date to somewhere around 1890. The overall folded length from front to back is 5.5" giving a full tube length of about 11". They have a celluloid adjustable headband.

They are impressive in their ability to improve speech understanding in noise due to the boost in high frequencies through the resonance of the narrow tube leading to the ear.

This pair was purchased from Holland.

There are a series of stiff metal wires in the middle of the opening. (See picture at right.) It may have been thought that the vibration of these from sound also increased the high frequencies, or, perhaps they were to discourage flying insects from entering the device.
