Environmental <strong>Noise</strong> Levels, A3 – Cnr Bells Lane and <strong>Mangoola</strong> Road<br />
<strong>Mangoola</strong> <strong>Coal</strong> was inaudible.<br />
Insects were primarily responsible for the measured levels. Road traffic engine noise and a<br />
train contributed to the measured L A1, L A10 and L Aeq.<br />
Frogs, ducks, dogs, a rural continuum, road traffic tyre noise, a train horn, cows and breeze in<br />
foliage were also noted.<br />
