Block 2

At a 50 metre separation distance the patron noise levels would be:

     •    0600 to 0700 hours:           83 dB(A) LWA – 42 (distance) – 5 (residential balcony solid balustrade)
                                        = 36 dB(A) LAeq,adj,T.

     •    0700 to 1800 hours:           93 dB(A) LWA – 42 (distance) – 5 (residential balcony solid balustrade)
                                        = 46 dB(A) LAeq,adj,T for 150 diners;

     •    1800 to 2200 hours:           93 dB(A) LWA – 42 (distance) – 25 (noise reduction for enclosing dining
                                        area) = 26 dB(A) LAeq,adj,T for 150 diners;

     •    2200 hours to midnight: 93 dB(A) LWA – 42 (distance) – 25 (noise reduction for enclosing dining
                                  area) = 26 dB(A) LAeq,adj,T for 150 diners.

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 2 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 noise limit. Alternatively, if there were only up to 100
diners present, then their noise level would be 2 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 West

The closest residential apartments to the west have no line of sight to the 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 20 dB(A) with all windows and
operable walls open.

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

     •    0600 to 0700 hours:           86 dB(A) LWA – 40 (distance) – 20 (roof acting as acoustic barrier) = 26
                                        dB(A) LAeq,adj,T.

     •    0700 to 1800 hours:           97 dB(A) LWA – 40 (distance) – 20 (roof) = 37 dB(A) LAeq,adj,T.

     •    1800 to 2200 hours:           97 dB(A) LWA – 40 (distance) – 20 (roof) = 37 dB(A) LAeq,adj,T.

     •    2200 hours to midnight: 97 dB(A) LWA – 40 (distance) – 20 (roof) = 37 dB(A) LAeq,adj,T.
