目前英国的噪声控制仍沿用一九七二年的实施规范。此规范系由工业健康咨询委员会制订,并经健康与安全行政部门所查询。这个委员会在很大程度上是参照美国的规程提出推荐噪声暴露极限值的。在90分贝(A)下,连续的噪声暴露达到8小时则构成危险。对不同声级,在其他时间间隔下的噪声暴露危险性问题,可由推算等效的连续声级和使用付印在规范中的计算图表而得知。图表如图所示。 At present, the UK’s noise control still follows the 1972 implementation rules. This specification was developed by the Industrial Health Advisory Committee and was consulted by the Health and Safety Administration. This committee to a large extent refers to the recommendations of noise exposure limits in the United States. At 90 decibels (A), a continuous noise exposure of 8 hours poses a risk. For different sound levels, the risk of noise exposure at other time intervals can be deduced from the calculation of equivalent continuous sound levels and the use of calculation charts printed in the specifications. The chart looks like this.
