Abstract
As part of ongoing efforts to investigate human factors issues that affect human performance on current naval platforms, a noise survey and communication study was conducted on the HMCS Montreal. The results will provide guidance on the optimization of layout within critical control space on future naval platforms. The average noise levels in four critical control spaces, the Bridge, operations room, communications control room (CCR) and machinery control room (MCR), exceeded the North Atlantic Treaty Organisation (NATO) Standardisation Agreement (STANAG) 4293 limits. The noise levels were the highest in the CCR, indicating that increased vocal effort is required to communicate over short distances. The questionnaire results indicated that CCR crewmembers had more difficulty with face-to-face communication than crewmembers in other control rooms. Noise levels logged from the communication headsets in the Bridge and operations room were high enough to cause concern for headset noise exposure when the headset was at full volume. The results provide information about noise levels during quiet watch and action stations in four critical control spaces, which will support modeling and simulation efforts for workplace layout optimization.
