                     Further analysis of the measurement data was undertaken, specifically
                     comparison of the LA90 and the LA10 for each 15-miinute measurement period.
                     These parameters are used by the Office of Liquor and Gaming Regulation to
                     assess the appropriateness of noise emissions, with the criterion prior to 10pm set
                     at LA10,adj ≤ LA90 + 10 dB.
                     Table 5:       Comparison of average difference between 15-minute LA10 and LA90

                                                       Measured Sound Level, dB(A)

                     The results in Table 5 demonstrate that the present operation can be regarded as
                     complying with the pre-10pm OLGR criterion. Moreover, the difference between
                     the LA10 and LA90 during the operating times of the premises is consistent with the
                     ambient noise in the area i.e. noise from the premises is not dominant.


6 Suggestions for Improvement
                     Although the noise levels from the premises achieve the noise criteria, the
                     following measures can be considered to attenuate noise further at the adjoining
                     residence:


                     Car Park Noise (Kingsgate Drive frontage)
                               Fix additional palings to the approximately 1.5 m high fence adjoining the
                                carpark at the front of the premises. The palings should be offset to the
                                existing ones such that the fence becomes a solid acoustic barrier.

                     Patron Noise

                               Remove all chairs/tables from the veranda facing Kingsgate Drive.
                               Close the dining area windows on the Kingsgate Drive frontage when
                                groups are using the dining area.
