Noise Limits

At a separation distance of greater than 50 to 100 metres the noise from the quad bikes using the
test/training circuit would be relatively constant and best described as ‘steady state’ noise. For steady
state or constant noise the most appropriate noise limit is the ‘background plus allowance’ criteria,
which is background plus 5 dB(A) for the daytime, from 0700 to 1800 hours. This noise limit is
expressed as the average of the maximum source noise levels, adjusted for any tonal and/or
impulsive components, which is equivalent to the noise level exceeded 10% of the sample duration,
denoted Lajo,t-

This is the noise limit that was applied in the initial version of this report, and is still considered
appropriate.

In addition to the above the Environmental Protection (Noise) Policy 2008 has the following
requirement with respect to background creep for steady state noise (which is the noise of the
airconditioning plant):
“10 Controlling Background Creep

(1) This section states the management intent for an activity involving noise.

(2) To the extent that it is reasonable to do so, noise from an activity must not be —

a) For noise that is continuous noise measured by Lago,r — More than nil dB(A)
greater than the existing acoustic environment measured by Lago,r; OF ... *

BACKGROUND NOISE LEVEL
After the April 2012 noise assessment of the quad bikes, a short ambient noise assessment was
conducted, with the results detailed in Table 1. Appendix A details the measurement equipment,

equipment settings, calibration, monitoring location and atmospheric conditions and Appendix B for
the complete set of results.

Subsequent to the above brief background noise assessment, a longer term assessment was
conducted from monitoring location A and just north of the residence at 295 Tablelands Road, set
back from Tablelands Road a similar distance as the residence at this address — refer Table 2 for
details. Appendix C details the measurement equipment, equipment settings, calibration, monitoring
location and atmospheric conditions. . ‘ | ol
