Describes the types of noise assessment which may be required in an occupational noise management program and the procedures and measuring instrumentation required to perform these assessments.

Scope

This Standard sets out requirements for and provides guidance on the types of noise assessments which may be necessary and suitable noise measuring instruments to carry them out. The procedures for noise measurement are also included. The type and detail of assessments carried out will depend on the use that is to be made of the information obtained. The type of measuring instruments and procedures to be used for the measurement of noise levels will depend on such factors as the type of workplace, type of noise, work patterns and information required. The general objectives of these assessments are as follows:
(a) To determine the exposure to noise of all people likely to be exposed to excessive noise. For the purpose of this Standard, the exposure to noise of each person is established in terms of-
(i) eight-hour equivalent continuous A-weighted sound pressure level (LAeq,8h) or
A-weighted noise exposure (EA,T); and
(ii) the peak sound pressure level (Lpeak).
Exposure to noise is taken to be that determined at the person's ear position without taking into account any protection which may be afforded by personal hearing protectors.
(b) To obtain more specific information that will help senior management decide what measures to take to reduce noise.
(c) To check the effectiveness of any control measures which have been applied.
(d) To assist in the selection of appropriate hearing protectors where other control measures are not practicable, or will take some time to plan and implement.
