NOISE IN SMALL CRAFT

An understanding of the phenomenon of noise, its psychological and physical effects on men and its minimization is becoming increasingly important to naval architects and marine engineers as a result of legislation, insurance requirements, community reactions and action by trades unions and workers' councils. The purpose of this series of articles is to explain the terms used by acoustic engineers and the phenomenon of noise itself, to give a measure of its effect on people and, finally, methods by which engineering estimates may be made of its possible intensity in the design state. Once a ship has been built and the engine room fitted out, it is virtually impossible to reduce noise levels without prohibitive cost levels. At the design stage, however, it is possible to estimate the noise level of a 'raw' design and the effect of silencers, special mountings and similar devices and so to reduce the residuary noise to a minimum.
