Provides guidance on the management of noise control in occupational settings which are applicable to all types of workplaces, large or small, and to all types of noise. It provides procedures for noise control in existing workplaces. It also provides technical information on basic noise control techniques applicable to both new and existing workplaces.

This Standard provides requirements and guidance on the management of noise control in occupational settings and applies to all types of workplaces and to all types of sounds. Sections 2, 3 and 4 are respectively concerned with procedures for incorporating noise control in the design of new workplaces, the implementation of noise control procedures in existing workplaces and the provision of complementary technical information on basic noise control techniques applicable to both new and existing workplaces.
