The Audiphone is a new instrument made of a peculiar composition, possessing the property of gathering the faintest sounds (somewhat similar to a telephone diaphragm), and conveying them to the auditory nerve, through the medium of the teeth. The external ear has nothing whatever to do in hearing with this wonderful instrument.

It is made in the shape of a fan, and can be used as such, if desired. (See fig. 1, page 4.)

When adjusted for hearing, it is in suitable tension and the upper edge is pressed slightly against one or more of the upper teeth. (See figs. 2 and 3, pp. 4 and 5.)

Ordinary conversation can be heard with ease. In most cases deafness is not detected, it being generally supposed, as is the experience of the inventor, that the party deaf, is simply amusing himself with the fan.

The instrument also greatly facilitates conversation by softening the voice of the person using it, enabling—even in cases of mutes—the deaf party to hear his own words distinctly.

Those Born Deaf can Hear, and the Dumb are enabled to Learn to Speak.

Mutes, by using the Audiphone according to the directions on page 6, can hear their own voice and readily learn to speak.
