Abstract:

A comprehensive program of research has been initiated by the Human Engineering Laboratory to examine the hearing requirements of soldiers in a variety of operational contexts and to determine the effects of hearing loss on performance. The initial focus of this program is on the aural detection and identification of combat-relevant sounds. One of the most important contributions of the present effort has been the development of a detection model which incorporates the ears analysis of incoming energy into critical bands of frequencies, and its integration of energy arriving during a period of 200 msec. Based on these theoretical considerations a unique computer-based analysis procedure was developed, which was used to provide a prediction of the critical bands of primary importance in the detection of representative combat-relevant sounds.
