Method for rating industrial noise affecting mixed residential and industrial areas
Methods for determining the level of industrial noise affecting mixed residential and industrial areas.
This British Standard describes methods for determining, at the outside of a building:
a) noise levels from factories, or industrial premises, or fixed installations, or sources of an industrial nature in commercial premises; and
b) background noise level.
This standard also describes a method for assessing whether the noise referred to is likely to give rise to complaints from people residing in the building. This standard may be helpful in certain aspects of environmental planning and may be used in conjunction with recommendations on noise levels and methods of measurement published elsewhere. The method is not suitable for assessing the noise measured inside buildings or when the background and rating noise levels are both very low. Use of the standard to obtain noise ratings and to assess the likelihood of complaints is given in this standard’s annex.
