6 Rodd Close (RC3) Measurement 1, Night time Environmental Noise Levels At Rodd Close 19 Jul 13, 0006 hours LA1 LA10 LAeq LA90 LA1 LA10 LAeq LA90 Rixs Creek exhaust continuum Road traffic exhaust noise Rixs creek engine/fan continuum Road traffic tyre noise LAmax: db LA1: db LA10: db LA: 41 db LAeq: 42 db LA90: 38 db LAmin: db LA10: 37 db LAeq: 32 db Figure 5 Environmental Noise Levels, Rodd Close Rixs Creek was audible for an exhaust and engine/fan continuum, one instance of transmission/diff noise and two impact events which generated the site only L A10 of 37 db. Road traffic noise was primarily responsible for all measured levels. Rixs Creek was a minor contributor to measured levels. Insects and frogs were noted.

7 Rodd Close (RC3) Measurement 2, Night time Environmental Noise Levels At Rodd Close 19 Jul 13, 00 hours LA1 LA10 LAeq LA90 LA1 LA10 LAeq LA90 Rixs Creek exhaust continuum Road traffic exhaust noise Rixs creek engine/fan continuum Road traffic tyre noise Bats LAmax: 62 db LA1: 49 db LA10: 44 db LA: db LAeq: 42 db LA90: 38 db LAmin: db LA10: 37 db LAeq: 33 db Figure 6 Environmental Noise Levels, Rodd Close Rixs Creek was audible for an exhaust and engine/fan continuum and three instances of transmission/diff noise, which generated the site only L A10 of 37 db. Road traffic noise was primarily responsible for all measured levels. Rixs Creek was a minor contributor to measured levels. A bat was responsible for the measured L Amax. Insects and frogs were noted.

8 Retreat Road (RC4) Measurement 1, Night time Environmental Noise Levels At Retreat Road 19 Jul 13, 0058 hours LA1 LA10 LAeq LA90 LA1 LA10 LAeq LA90 Rixs Creek exhaust continuum Other mining continuum Rixs creek engine/fan continuum Other mining continuum Frogs and insects LAmax: 51 db LA1: 46 db LA10: 44 db LA: 41 db LAeq: 41 db LA90: 39 db LAmin: 36 db LA10: 44 db LAeq: 39 db Figure 7 Environmental Noise Levels, Retreat Road Rixs Creek was audible for an exhaust and engine/fan continuum and eight instances of exhaust/engine surges due to trucks entering/exiting the ROM, which generated the site only L A10 of 44 db. A car-cooling click generated the measured L Amax. Rixs Creek were primarily responsible for the measured L A1, L A10 and L Aeq, and contributed to the L A90. Noise from another mining operation contributed to the L Aeq and L A90. Insects and frogs were minor contributors to measured levels.
