The WA Occupational Safety and Health Regulations 1996 set the occupational exposure standard (action level) for workers without wearing hearing protection, as followings:
- a daily noise exposure level, LAeq,8h of 85 dB(A); and
- a peak noise level, LC,peak of 140 dB(C) or 140 dB(lin) for mine sites.
An LAeq,8h of 85 dB(A) means that the actual energy of varying noise levels experienced by a person over the working day is equivalent to the energy from 8 hours of exposure to a constant A-weighted noise level of 85 decibels.
Where employees are exposed to levels above the exposure standards it is a requirement under the Regulations that hearing protection is provided and selected in accordance with AS/NZS 1269.3 and comply with AS 1270.
The Code of Practice for Managing Noise at Work places 2002 states that noise assessments are to be conducted where a noise hazard is identified and at intervals of 5 years from the initial survey or when there is a significant change in the work process, equipment, working area or shift arrangements.
