Provides guidance in noise control in respect of engineering construction, maintenance and demolition works. It covers hearing protection of persons on site, investigation and identification of noise sources, neighbourhood nuisance, measurement of sound and its assessment and control of noise at source and its spread. Appendices provide information on statutory requirements estimation of noise from sites (with examples). A-weighted levels of neighbourhood noise, sound levels from construction, maintenance and demolition plant, remedies and their effectiveness according to machine and source of noise, and use of acoustic screens and enclosures.

This standard provides guidance in noise control in respect of engineering construction, maintenance and demolition works, including guidance in investigation and identification of noise sources, measurement of sound, and its assessment, with a view to the planning of measures for noise control.
