Weather Observations<br />

measured levels.<br />

Road traffic noise, breeze, dogs, an<br />

aircraft and a continuum in the rail<br />

corridor were also noted.<br />

Cloud cover: 0/8, Wind<br />

speed at 10 m: 1.2 m/s,<br />

VTG: -1 degrees Celsius<br />

per 100 m<br />

<strong>Mangoola</strong> <strong>Coal</strong> was inaudible.<br />

Insects and frogs generated the<br />

measured levels.<br />

Breeze in foliage, breeze on the<br />

microphone, road traffic noise, bats,<br />

cows and a continuum from Sandy<br />

Hollow direction were also noted.<br />

Cloud cover: 1/8, Wind<br />

speed at 10 m: 3.8 m/s,<br />

VTG: 3 degrees Celsius<br />

per 100 m<br />

Engine continuum and rear dump<br />

trucks from <strong>Mangoola</strong> <strong>Coal</strong> were<br />

audible throughout the<br />

measurement. Track noise, train<br />

loading noise, CHPP continuum<br />

and an impact noise were also<br />

noted. These sources resulted in a<br />

<strong>Mangoola</strong> <strong>Coal</strong> only LAeq of 30 dB.<br />

A surge in engine continuum<br />

generated the <strong>Mangoola</strong> <strong>Coal</strong> only<br />

LA1,1min of 35 dB.<br />

Insects and frogs generated the<br />

measured levels.<br />

Cows were also noted.<br />
