520  ‎$a‎When performing watches at sea, sonar operators experience a wide variety of stressors that may adversely affect their target detection performance. These include fatigue from lengthy work periods, fragmented sleep, poorly designed work stations, noise, air contamination, platform motion, and the threat of enemy action among others. However, in the opinion of the operators themselves, none of these stressors affects performance so strongly as the monotony of watchstanding. Yet, maintaining a high level of vigilance for the occurrence of such signals is of critical importance. Not only are tactically important signals rare, but they can also be of brief duration and of very low intensity compared to other sound sources in the ocean. This places even greater emphasis on the operators' state of vigilance and makes latency of detection a prime measure of operator effectiveness
