Body Style Transistor Hearing Aids

Acousticon Model A-290 Transistor Hearing Aid

The Acousticon model A-290 was a rather unusual hearing aid. It was a small barrette-style hearing aid that was manufactured by Dictograph Products, Inc. of New York in 1957.

It was about the size of a large BTE hearing aid, having dimensions of 2" by 1" by ˝".

This needed to be set with a screwdriver. The red protrusion on the right was the sliding volume control—up for loud and down for soft/off. (See also in the picture below.)

This hearing aid apparently came in several different clip configurations. The pocket clip version is shown. In addition to this one, which clipped to the wearer's pocket, there was a tie-clip version for the men and a barrette clip so a hard of hearing woman could wear it in her hair. There was even a version that clipped to the wearer's glasses.

In keeping with its relatively small size, the Acousticon A-290 came with a miniature button receiver. The picture on the right shows the standard size receiver (left) and the miniature Acousticon A-290 button receiver (right).
