Preferences for Blue and White Light in Sonar Compartments

摘要

Twenty sonar crews (mean = 9.7 men) undergoing refresher training in the Sonar Operational Trainers (SOT) for two to five 8-hour days evaluated the acceptability and effectiveness of blue and white ambient lighting. In addition, five crews evaluated the white lighting at sea. Of the nearly 200 men tested in the SOT, two-thirds preferred blue to white lighting, although there was general agreement that such pieces of equipment as the AN/BQQ-3 and AN/BQR-21 should be white lighted. Of the five crews tested at sea, four preferred white and only one preferred blue. Two of the crews that preferred white had originally preferred the blue lighting when tested in the SOT. Possible reasons for this change are discussed. (Author)
