criteria shown in brackets.

Notes: Day & Evening 7am-10pm, Night 10pm-7am.

Crowd noise sources are predicted to comply at offsite receiver locations at all times.

The predicted acoustic quality objective noise levels for the onsite receivers were calculated and the
SoundPLAN results are shown in Appendix D. To achieve the internal noise levels the recommendation is to
provide the dwellings with façade treatment to achieve a minimum total noise reduction of 25dB with
facades closed. Refer to Section 7 for recommended noise mitigation measures.
Table 16 presents the predicted background creep noise levels at the nearest sensitive receivers. Background
creep applies to offsite receivers.

*A 1dB exceedance of criteria is considered a ‘marginal compliance’ as a 1-3dB change in noise level is typically not
discernible to the human ear in an environmental setting.

Crowd noise sources are predicted to comply or marginally comply with the background creep criteria at
offsite receiver locations at all times.
