4.2 Amplified Music and Live Entertainment

Noise emanated by licensed premises is regulated by Office of Liquor and Gaming Regulation
(OLGR). The noise limit criteria applied to provision of amplified entertainment is contained in the
Liquor Act 1992 (Section 187), and the subordinate Regulation (Section 28) with a technical
guideline produced by the Department for Acoustic Assessment.

Section 187(1) of the Act states that if unreasonable noise is emitted by a licensed premises, an
investigator may give written notice that the unreasonable noise be stopped, reduced to
reasonable levels, or the premises be closed. A definition of unreasonable noise is set within the
Liquor Regulation 1992, and is as follows:

“28 Unreasonable Noise-Act, s187(5)

   For section 187 of the Act, the limits for noise are-

       (a) between 6 a.m. and 10 p.m. – the adjusted maximum sound pressure level LA10, plus
           adjustments for tonal and impulse components, exceeding the background level LA90 by
           more than 10dB(A); or
       (b) between 10 p.m. and 6 a.m. – the sound pressure level LOCT10, in a full octave band with
           centre frequencies from 63 HZ to 2000 HZ, exceeding the background level LOCT90 by
           more than 8dB in any octave band.”

The guideline for assessment of noise impacts require measurements be conducted in “C”
weighting, rather than the “A” weighting required in the Regulation. This is to focus on the lower
octaves register of the noise (e.g. ‘bass’ frequencies), which is often the problem associated with
provision of indoor amplified music.

The measured broadband and octave band ambient noise levels are presented in Table 4 and
Table 5. Graphed results of unattended noise monitoring period are presented in Appendix B. The
octave band noise results are based upon measured levels conducted between 11:00pm and
1:00am.
