Complying with International Maritime Organization Resolution MSC.337(91) Noise Level Code

One of the best things a marine operator can do for its crew or passengers is prioritize their comfort by reducing shipboard noise. Commercial and military marine vessels can be subject to very high noise levels produced by everything from onboard activities to aircraft. At worst, this noise can be hazardous—disruptively noisy environments can lead to discomfort, sleep-deprivation, and even hearing loss, which can in turn lead to lower job performance, safety risks, and diminished quality of life. Evidence shows that when noise levels are controlled, crews can be more productive and the potential for injury is reduced.
