This Standard sets out general procedures for the description and measurement of environmental noise including repetitive impulsive noise. This Standard does not apply to the measurement or assessment of en route air, rail or water transportation or road transportation on public roads. It also does not apply to noise which consists solely of discrete impulses such as those encountered in shooting and blasting. This Standard defines the basic quantities to be used for the description of noise in community environments and describes basic procedures for the determination of these quantities.It excludes the setting of environmental noise criteria. Such levels are set by regulations or organizational policy, not by Standards Australia.In this Standard all sound pressure level descriptors are A-weighted.
