No adjustments for crowd orientation were applied to consider a ‘worst-case’ assessment. A
reference spectrum was applied to the overall sound power level using guidance provided in the
Association of Australasian Acoustic Consultants (AAAC) Licensed Premises Guideline V3.0.

4.7.3.3 Outdoor Speakers
We understand that outdoor speakers are proposed for the exterior dining area. To determine
indicative noise impacts, four (4) typical wall mounted speakers were input into the noise model,
facing west towards the licensed bowling green area angled at 45° downward.

Each speaker was set to a sound power level of 88 dBA using a reference spectrum from Live It
Acoustics measurement database. Based on omnidirectional radiation into free space, this would
be approximately equivalent to a sound pressure level of 70 dBA at 3m from the source.

No outdoor speakers are located in the eastern areas of the site.

4.7.4 Playground
The AAAC Guideline for Childcare Centre Acoustic Assessment provides sound power levels
(LAeq,15min dBA) for 10 children playing within the age groups 0 – 2, 2 – 3 and 3 – 5, as shown
in Table 11.

                                             Table 11. Sound power levels.

The guideline also provides an equation to calculate noise levels for more or less than 10 children
within these age ranges, as shown below:



                                      𝑆𝑊𝐿 = 10 𝑐ℎ𝑖𝑙𝑑𝑟𝑒𝑛 + 10𝑙𝑜𝑔 (𝑛/10)

                                        Where:

                                        10 children       =        SWLs stated in Table 11

                                        n                 =        Number of children

We have been informed that typically, no more than 6 children aged from 3 to 5 utilise the space.
For the purposes of a conservative assessment, it has been assumed that 10 children aged 3 to
5 years utilise the playground space.
