Entertainment Noise Assessment

 this mechanical plant services only the venue or additional tenancies
 within the shopping centre complex.

 Mechanical plant was confirmed to be operational during the intrusive
 assessment, however, was not audible during any noise measurements.
 The contribution from mechanical plant has therefore been considered
 when determining the noise limits.

 For all background noise measurements, no mechanical plant associated
 with the venue was audible.



 3.8 Patron noise
 To determine the level of noise being caused by patrons, a prediction      G51 Check Item 44 ☐

 model for patron noise was prepared using the methodology outlined in
 Prediction of Noise from Small to Medium Sized Crowds, 2011 (M.J
 Hayne, et al).

 The following table provides the assumed crowd size for each specific
 licensed area within the venue. The crowd size is based on advice
 provided by the venue to Live It Acoustics and is expected to be
 maximum patronage on a busy Saturday night.

                        Indoor dining area (nightclub)   300       104

                        Outdoor dining                   20        87

 No adjustments for crowd orientation were applied.

 Spreadsheet calculations were conducted to predict the sound pressure
 level received at RAPs. To convert sound power levels (𝐿𝑤) to sound
 pressure levels (𝐿𝑝) at the RAPs, the following formula was used:

                           𝐿𝑝 = 𝐿𝑤 − 20 log 𝑟 − 11 + 𝐷𝐼

                   Where:

                              r = distance from noise source

                             DI = directivity index (assumed to be 3 dB).
