MCU16/0079 Appendix F - Environmental Noise Imact Assessment

5.3       New Function / Dining Area Amplified Entertainment Noise Predictions
Amplified entertainment from the new function / dining extension has been assessed at the nearest
offsite receivers. Based upon the location of the nearest receivers we have predicted the allowable
noise source levels with windows and doors closed (Table 11) and windows and doors open
(Table 12) which will achieve compliance with the Liquor and Gaming noise criterion set out in
Section 4.2 of this report.

We note that the following parameters have been applied in our noise modelling for the floor levels
where amplified entertainment is proposed:
 New external walls to be constructed to achieve an Rw rating of 50.
 Roof / ceiling constructed to achieve an Rw rating of 50.
 External doors and windows of the function / dining extension, children’s lounge and the dining
    lounge doors (to the new alfresco balcony) are kept closed during high level amplified
    entertainment; therefore, sound lock systems should be incorporated where access to outdoor
    areas is required.
 A minimum Rw 34 (i.e. 10.76mm laminate in acoustic grade frames and acoustic seals).
 The function / dining extension will be air-conditioned or have sealed mechanical ventilation.

It is noted that should a lower level of amplified sound be required a lower level of acoustical building
shell treatment could be achieved, alternatively, if higher sound levels are required, a higher level of
building treatment would be needed. Such design elements could be determined at detailed building
design prior to the Building Approval stage.
