Abstract : Studies were conducted to ascertain whether the noise level of a new type submarine would be incompatible with personnel habitability, interfere with speech communication or cause auditory damage. While certain spaces within the ship were classified as 'very noisy', still the noise level was not sufficient to cause auditory damage. The noise levels found were considerably below safety limits set by any nationally known group. In engineroom workspaces, the speech interference level was always low enough to render speech intelligible over a distance of a couple of feet. In other workspaces, noises were not intense enough to deteriorate speech beyond reasonable limits to reduce habitability in general. There is no indication that service aboard vessels of this type would cause damage to hearing, or be unduly uncomfortable. (Author)
