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):                     44 dB(A) LAeq,adj,T;
     •    night-time (2200 to 0700 hours):                  41 dB(A) LAeq,adj,T.

For the early morning the noise of 30 diners complies with the noise limit, with the dining area
completely open. For the daytime, with up to 150 diners, the noise limit is also complied with, for the
dining area completely open.

For the evening time period, with 150 diners, the noise limit is exceeded by 3 dB(A) for the dining area
completely open and, therefore, at 1800 hours, the dining area would need all windows and operable
walls closed for 150 diners to comply with the evening noise limit. Alternatively, if there were only up to
100 diners present, then their noise level would be 3 dB(A) less than the noise of 150 diners, and the
dining area could remain completely open.

For the night-time period with 150 diners, the noise limit is complied with provided that all of the
windows and operable walls of the dining area are closed.


Closest Residential to North

The next closest residential apartments with direct line of sight to the dining area are to the north –
Block 14, and to the north-north-west, Block 2. Block 14 is approximately 75 metres from the dining
area and has line of sight to approximately 80% of the dining area. Block 2 is approximately 50 metres
from the dining area and has line of sight to approximately 60% of the dining area. For 150 diners 80%
= 120 diners with an associated noise level of 95 dB(A) LWA. For 150 diners 60% = 90 diners with an
associated noise level of 93 dB(A) LWA


Block 14

At a 75 metre separation distance the patron noise levels would be:

     •    0600 to 0700 hours:           85 dB(A) LWA – 46 (distance) – 5 (residential balcony solid balustrade)
                                        = 34 dB(A) LAeq,adj,T for 30 diners;

     •    0700 to 1800 hours:           95 dB(A) LWA – 46 (distance) – 5 (residential balcony solid balustrade)
                                        = 44 dB(A) LAeq,adj,T for 150 diners;

     •    1800 to 2200 hours:           95 dB(A) LWA – 46 (distance) – 5 (residential balcony solid balustrade)
                                        = 44 dB(A) LAeq,adj,T for 150 diners;

     •    2200 hours to midnight: 95 dB(A) LWA – 46 (distance) – 25 (noise reduction for enclosing dining
                                  area) = 24 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):                     44 dB(A) LAeq,adj,T;
     •    night-time (2200 to 0700 hours):                  41 dB(A) LAeq,adj,T.

The early morning, daytime and evening noise limits are complied with for the above scenarios, for
Block 14, for all of the dining area windows and operable walls open. For 2200 hours to midnight time
period, with 150 diners, the noise limit is exceeded by 3 dB(A) for the dining area completely open and,
therefore, at 2200 hours, the dining area would need all windows and operable walls closed for 150
diners to comply with the noise limit.
