Glossary
 Term                Description
 AS1055              Australian Standard AS1055:2018 Acoustics – Description and measurement of environmental noise.
 Background Noise    Background noise is the term used to describe the underlying level of noise present in the ambient noise, measured
                     in the absence of the noise under investigation when extraneous noise is removed.
 BOM                 Bureau of Meteorology.
 CEML                Close external monitoring location. A location selected within 25m of the boundary of the licensed premises, in the
                     general direction of each of the representative affected premises.
 dBA                 A-weighted decibels. The sound level meter replicates the human response of the ear by using an electronic filter
                     which is called the “A” filter.
 dBC                 C-weighted decibels. C-Weighting is usually used for peak measurements and also in entertainment noise
                     measurements, where the transmission of bass noise can be a problem.
 dBZ                 Z-weighted decibels. Z-Weighting is a flat frequency response of 10Hz to 20kHz ±1.5dB.
 EPA 94              Environmental Protection Act 1994.
 Free-field          Free-field is a situation in which no sound reflections occur.
 Impulsive noise     Having a high peak of short duration or a sequence of such peaks. A sequence of impulses in rapid succession is
                     termed repetitive impulsive noise.
 L10                 The sound pressure level that is exceeded for 10% of the time for which the given sound is measured.
 L90                 The level of noise exceeded for 90% of the time. The bottom 10% of the sample is the L90 noise level expressed
                     in units of dB(A).
 Leq                 The “equivalent noise level” is the summation of noise events and integrated over a selected time period.
 NMM                 Noise Management Manual Version 4.01.
 RAP                 Represented affected premises. A premise identified by the acoustic consultant that may be adversely affected by
                     noise emanating from the licensed premises.
 RPL                 Reference point locations. A measurement location in a public place, near to a representative affected premise and
                     that is easily and safely accessible at all times.
 SLPA                Specific licensed premises areas. The specific licensed premises area should be selected such that is representative
                     of the typical loudest area within the licensed premises. A monitoring location within each of the identified
                     entertainment-producing areas to be used to determine the maximum operating noise level for the area (3m from
                     the source/speaker may be suitable but not obligatory).
