- Abstract
Nowadays, more and more consideration is being given to environmental issues. Formerly, noise was considered a necessary, but harmless, evil. Today, excessive noise is considered a form of pollution which, in the long run, may cause permanently reduced hearing. As a consequence, authorities now demand that noise levels are kept below certain specified limits. Today, there are numerous national and international codes which both recommend, and demand, maximum permissible noise levels in the various parts of a ship. The greater demand for noise limitation in the maritime area has, of course, aroused wide interest. Consequently, greater demands are now made on the engine designer to provide more detailed and precise information regarding the various types of noise emission from the engine. After a brief definition of what noise actually is, this paper will attempt to clarify "noise" as applied to MAN B&W's two-stroke engines, and will then go on to discuss the primary noise sources and types of engine-related noise emissions, noise level limitation, and the current situation in relation to noise
