THE NSMC SONAR OPERATOR ALERTNESS RESEARCH APPARATUS: DESCRIPTION AND INSTRUCTIONS FOR USE

Abstract

The design was investigated of a simple portable system with which to perform research on sonar operator vigilance, in the laboratory and especially while under-way in submarines. An inexpensive automatic system was derived to present signals and background noise to a listener, and to record his responses (together with strengths of signals and noise) so that over extended vigilance testing sessions the detection performance of the operator may be specified at selected intervals. The system is useful as a research tool in specifying differences among listeners in detection ability, in resistance to monotony, in effect of signal density, time on watch, drugs, group interactions, etc.
