Industrial noise control. (1867 words) |
| Industrial noise pollution is an ever growing problem and its management is centred around many pieces of legislation, standards, guidance documents, etc. many of which frequently contradict each other. |
| BS 4142: 1990 "Rating Industrial Noise Affecting Mixed Residential and Industrial Areas" is the most important guidance document here and is the one most frequently used by environmental health officers to determine the degree of nuisance from a factory. |
