4. Discussion and Recommendations
4.1 Compliance with Noise Limits

The noise emissions from Village Bicycle cafe, under busy operational conditions, considering
amplified music of up to 85dB(A)L,o, at 3 m from the speaker and typical patron noise emissions in
the internal and outdoors dining area, are within the noise limit applicable before 10:00pm. After
10:00pm the noise limit is marginally exceeded in the 250Hz octave band. Whilst the calculated
sound pressure levels in the other octave bands are within the criteria, they are very close to the
limits.

Therefore, conditions on amplified music (speaker) and patron noise emissions are recommended
to ensure that the intrusive noise levels after 10:00pm at the nearest boundary of Bottlebrush
Townhouses are within the acceptable levels.

4.1.1 Recommended Levels for Amplified Music

To ensure compliance with the day-time/evening (6am to 1Opm) noise limit the instantaneous volume
level, at 3m from any of the speakers at Village Bicycle, must not exceed 85dB(A) or 90dB(C)Ll0
when measured at 3 metres from the speakers. This corresponds to the sound pressure level
measured when the speaker volume was set at its loudest during the attended noise measurements
on the 2nd of May 2015.

The Guideline for Acoustical Consultants - When Assessing Noise Associated with Entertainment
and Patrons at Premises Licensed Under the Liquor Act 1992 (Office of Liquor and Gaming
Regulation, 2010) provides a procedure for calculating recommended levels from amplified music.

This procedure considers noise emissions from amplified music only and does not consider patron
noise, thus it is provided only to establish the recommended instantaneous volume level at 3m from
any of the speakers at Village Bicycle cafe.

The results of the amplified music assessment are presented in Appendix F.

4.1.2 Recommended Levels for Patron Noise

Since patron noise is the primary concern associated with Village Bicycle cafe operations, based on
the results of the operational noise propagation modelling, operational noise levels for patron noise
emissions were determined. The maximum sound pressure levels, 3m from the outdoor dining areas
of Village Bicycle cafe, are presented in Table 4.1.
