Assistive Listening Devices (ALDs)

Acousticon Mystic Ear

 The Acousticon Mystic Ear was a large bone conducting device produced in the mid 1930s by Dictograph Products, Inc. It was the listening device for the "Silent Radio" that Fada  manufactured for Dictograph Products.

 The Mystic Ear was placed under your pillow. When you laid your head on the pillow, you heard the sound via bone conduction. Because others could not hear the sound, it was referred to as a "Silent Radio".

The Mystic Ear measures 3 ¼” by 1 ¾” by ¾”.
