Apparatus for Telephone-Tone Study.

Abstract

The report describes the technical principles used in designing and developing a tone-presentation system capable of presenting 16 tones to six subjects over telephone sets, for closely controlled presentation times. This experimental apparatus system was used to evaluate the suitability of proposed tones and tone combinations for use in a future telephone system. A 14-channel tape recorder was used to store the library of test tones. The remainder of the system required custom design to meet criteria of the experimental design. This tone-presentation system can readily be adapted to a wide range of other similar studies or tests.
