Title:	The Effect Of Electroacoustic Characteristics Of Low-Fidelity Circuitry Upon Speech Intelligibility
Author:	Smaldino, J; Harris, JD
Abstract:	Recorded speech tests were passed through 16 low-fidelity speech communication circuits, rated from good to poor, and listening panels underlined the key words heard. Mean scores among circuits (hearing aids) ranged from 53 to 75 per cent words correct. A total of 32 indices of electroacoustic characteristics was obtained or derived from measures of: transient, harmonic, intermodulation and frequency distortion; gain; and signal/noise ratio. Each index was correlated with speech intelligibility, and multiple correlations were derived for optimal prediction of speech intelligibility from a knowledge of the physical characteristics of any circuit.
