Entertainment Noise Assessment

 3.7.2 Sound system configuration during testing
 The sound system scenario used for testing involved all in-house sound        G51 Check Item 39 ☐

 systems operating cumulatively.

 The purpose of this test scenario was to determine the expected
 maximum intrusive noise level at each affected premises. A test signal
 was played through the loudspeaker systems, for the purpose of
 measuring intrusive noise levels at the locations described in Sections
 3.1 to 3.4. The source material was selected to be representative of the
 type of music proposed to be played at the venue (house / club music).

 The lowest noise limit calculated at the CEMLs across each of the 3
 scenarios (plus patron noise, refer to Section 3.8) is considered the final
 maximum noise limit at the CEML. This is expected to address
 cumulative noise generated by the venue.


 3.7.3 Meteorological conditions during testing
 Wind speed was collected immediately prior to and following the set of        G51 Check Item 40 ☐

 intrusive measurements, recording a wind speed of less than 5 m/s using
 a Kestrel 2000 anemometer.


 3.7.4 Method of conducting intrusive noise measurements
 Intrusive noise measurements were taken at each of the locations              G51 Check Item 41 ☐

 described in Section 3.1 to 3.4. The source material was played through
 the sound systems associated with the scenario concurrently, set at a
 sufficiently loud volume so that the signal was clearly audible and
 measurable. Where poor signal-to-noise ratio was experienced or where
 the signal was not audible at an identified RAP, the measurement was
 still undertaken, along with RPLs and CEMLs relevant to the RAP.

 3.7.5 Exclusion of extraneous noise events
 Extraneous noise events experienced during intrusive noise                    G51 Check Item 42 ☐

 measurements included: road traffic movements, pedestrian noise and
 birdsong. These noise events were excluded through the use of post-
 processing of the data (removal of contaminated data and recalculation
 of the L10 noise descriptor) or using a back-erase function on the sound
 level meter during intrusive measurements. The back erase function
 allows acoustic consultants to erase the last 5-seconds of noise
 measurements where the consultant identifies extraneous noise.


 3.7.6 Mechanical plant noise
 Mechanical plant associated with the venue was identified to be               G51 Check Item 44 ☐

 comprised of refrigeration equipment and air conditioning plant located
 directly above the main dining area on the rooftop. It is unknown whether
