Aural Detection Performance over a 129 Minute Simulated Sonar Watch

Abstract

Experienced sonar operators were exposed to conditions of simulated sonar watchstanding over a 129-min period. Successive measurements on the same non-alerted contact taken every 43 min during the detection period showed no significant change in initial detection. These results indicate that under conditions where the operator's vigilance is maintained by a not-unusual frequency of contact (operators were presented six contacts at random intervals during each 43-min period) no change in operator initial detection performance is encountered.
