Subjective Preferences and Detection Ranges in Sonar Control Rooms under Red and Blue Light.

摘要

This report summarizes the results of two studies conducted in sonar trainers at Naval Submarine School comparing red and blue ambient illumination in sonar control rooms. In one, a subjective assessment of blue, white, and red was made in the SSBN Sonar Operational Trainer; in the other, detection ranges were measured on the 21B64A/AN/BQQ-5A trainer under red and blue light. The sonar crews of two submarines voiced strong preferences for blue light while those of a third preferred red. Detection ranges did not change with the color of the illumination. (Author)
