In addition to the above it should be noted that there will be clear plastic blinds installed around the
perimeter of the roofline for the outdoor dining area and when these curtains are closed they will assist,
to a small extent, in further reducing any potential noise impact to the closest residential.


Closest Residential to West

The closest residential apartments to the west have no line of sight to the outdoor dining area, with the
closest residential in this direction being Block 3 at a distance of approximately 40 metres. The
intervening roof of the Facilities Building provides a noise reduction of approximately 14 dB(A).

At a 40 metre separation distance the patron noise levels would be:

        0600 to 0700 hours:           86 dB(A) LWA – 40 (distance) – 14 (roof acting as acoustic barrier) = 32
                                       dB(A) LAeq,adj,T, less 3 dB(A) for the residential balcony balustrade = 29
                                       dB(A) LAeq,adj,T.

        0700 to 2200 hours:           97 dB(A) LWA – 40 (distance) – 14 (roof) = 43 dB(A) LAeq,adj,T, less 3
                                       dB(A) for the residential balcony balustrade = 40 dB(A) LAeq,adj,T.

        2200 hours to midnight: 94 dB(A) LWA – 40 (distance) – 14 (roof) = 40 dB(A) LAeq,adj,T, less 3
                                 dB(A) for the residential balcony balustrade = 37 dB(A) LAeq,adj,T.

For the time varying noise of patrons laughing and talking the noise limits are:

        daytime (0700 to 1800 hours):                     50 dB(A) LAeq,adj,T;
        evening (1800 to 2200 hours):                     45 dB(A) LAeq,adj,T;
        night-time (2200 to 0700 hours):                  40 dB(A) LAeq,adj,T.

The daytime, evening and night-time noise limits are complied with for the above scenarios, for Block 3.


AMPLIFIED MUSIC

At the time of preparing this report no detail was available with respect to speaker locations. It has been
assumed that all speakers would be located immediately under the solid roof of the outdoor dining area,
and angled down as much as possible – area delineated by red rectangle in Figure 2.

It should also be noted that the café and outdoor dining areas will be licensed for the consumption of
alcohol and, as such, the noise of amplified entertainment will be controlled by the Office of Liquor and
Gaming Regulation, together with patron noise. OLGR will require a separate noise impact assessment
of amplified entertainment based on actual source noise level measurements conducted concurrently
from 3 metres from the speakers and at the closest sensitive receptors – in this situation the closest
residential apartments.

The amplified entertainment noise limits nominated below are based on calculation only and should be
considered preliminary, as actual amplified music noise level measurements will provide the required
level of detail to determine the actual amplified entertainment noise limits.

Based on the patron noise impact calculations the preliminary amplified music noise limits for the in-
house speaker system for amplified music should be the same as for patrons, but +5 dB to allow for the
additional barrier effect of the roof and the fact that these speakers will be located just below the line of
the ceiling.

Therefore the preliminary amplified music noise limits for the in-house speakers, located within the red
rectangle in Figure 2, are:

        daytime and evening (0700 to 2200 hours) = 92 dB(A) LWA, which is equivalent to 75 dB(A) + 5
         = 80 dB(A) LAeq,adj,T at 3 metres from the speakers;
