                 Noise Impact Assessment

                 4.7.3.1 Amplified Entertainment – Industrial Building
                 An industrial building noise source was input into the noise model, traced using the architectural
                 drawings in Appendix C – Design Drawings.

                 An amplified music and patron reverberant sound pressure level was estimated within the space
                 using the following parameters:

                      •    Estimated room volume given via the gross floor area (344m2) * the ceiling height (3.2m);
                      •    Average mid-frequency reverberation time of 1.0 seconds;
                      •    Amplified music sound power level of 111 dBA, based on Live It Acoustics’ measurement
                           database of a pair of 15-inch active loudspeakers.

                 Based on the existing entertainment area and speaker locations, the internal level incident to the
                 façade was calculated.

                 The building envelope construction materials were determined during site visits by Live It
                 Acoustics. The building materials used in the model are specified below:

                      •    8mm toughened glass (modelled achieving minimum Rw30 dB); and
                      •    Typical lightweight construction for the external façade (assumed Rw41 dB for walls and
                           roof structure)

                 The entry / exit doors to the courtyard are assumed to be closed. The exterior dining and main
                 entrance doors are assumed to be open within the noise model.

                 4.7.3.2 Patron Noise
                 Noise associated with patrons has been based on the technical paper ‘Prediction of Noise from
                 Small to Medium Sized Crowds’ (Hayne et al, 2011). The paper was based on attended noise
                 measurements conducted at a sample of premises to account for a range of patron numbers and
                 venue types. The analysis determined that the sound power level (LAeq) of a small-medium crowd
                 could be predicted by the equation:

                                                             LWAeq = 15 × log N + 64dB(A)

                           Where:

                                       LWAeq is the calculated patron A-Weighted sound power level
                                       N          is the number of patrons.

                 Patronage within the subject site has been determined based on approximately one patron per
                 two square-metres of floor space for internal and external areas.

                 The assumed patron numbers for each area and associated sound power levels are presented in
                 Table 10 below.
