Author(s)

Randall P. Wagner

Abstract

A description is given of the hearing aid testing done for the Department of Veterans Affairs. Emphasis is given to the determination of the insertion frequency response using Fast Fourier Transform (FFT) techniques, but the other measurements entailed are delineated. These include the measurement of saturation and sound pressure level, telephone coil sensitivity, total harmonic distortion, equivalent input noise level, and battery drain. The data resulting from these tests are included.
