scope:

This is a specification of the procedures which apply to noise control in the selection and installation of all plant equipment. It indicates the method of specifying maximum acceptable noise levels for plant and equipment, describes acceptable methods of tests for determining noise emission from equipment, and gives a guide to methods of calculation and presentation of data. It does not set noise limits because the acceptable limit for any location will depend on factors relevant to that location. Noise limits may also vary over the course of time as new information becomes available on the physiological effects of noise. The noise limits are the responsibility of the Principal.

Noise levels may be considered under the following headings:

(a) Hearing conservation.

(b) Speech and work interference.

(c) Community reaction.

(d) Accommodation.
