Ear Trumpets (Ear Horns)

Audiscope (Amplified) Ear Trumpet (Ear Horn)

The Amplified Audiscope was manufactured by the American Earphone Co. Inc. of  New York, NY around 1925, It is a two-section telescoping ear trumpet made of hard rubber with a resonant brass bowl added.

The addition of the resonant bowl increased the amplification of the Audiscope, so this was better for people with greater hearing losses than was the regular Audiscope.

The Audiscope is easy to identify, unlike many of the early ear trumpets. On the front at the bowl end it gives its name—Audiscope—and manufacturer—American Earphone Co. of New York.

The bowl has held to the amplified Audiscope by a clip that was screwed to the center of the bowl. The tapered shaft of the Audiscope couldn't pull out because of the smaller sized hole near the rim of the bowl.

The angled ear-piece screwed on to the narrow end of the second section. This made manufacturing the straight second second section easier.
