This Standard sets out general procedures for the description and measurement of
environmental noise, including repetitive impulsive noise. It defines the basic quantities to be used for the description of noise in community environments and provides basic procedures for the determination of these quantities.
The Standard applies primarily to noise emitted from industrial, commercial and residential premises. It excludes the setting of environmental noise criteria. Such levels are set by regulations or organizational policy.
This Standard does not apply to the following:
(a) The measurement or assessment of in-transit air, rail or water transportation or road transportation on public roads (which may be present in the ambient noise occurring at a location).
(b) Noise that consists solely of discrete impulses such as those encountered in shooting and blasting.
(c) Noise from wind farms.
In this Standard, all sound pressure level descriptors are A-weighted, unless stated otherwise.
NOTE: Guidelines for the application of this Standard are given in Appendix A.
The structure of this Standard is as follows:
(i) Definitions and symbols.
(ii) Instrumentation.
(iii) Measurements -
(A) general locations, times, conditions and methods for general measurements;
(B) methods for assessing specific environmental noise situations;
(C) methods for setting objectives and specifications; and
(D) methods for assessing conformance to objectives and specifications.
(iv) Reporting and information to be recorded.
(v) Appendices.
