Throughout the source noise level measurements metal fabrication activities within the Allstar Metal
Fabrication building were representative of normal activities and all of equipment associated with the
highest potential noise sources was being operated.


NOISE LEVEL IMAPCT


Eastern Boundary

The noise level reduction from 15 metres from the eastern end of the Allstar Metal Fabrication building
to the closest part of the eastern site boundary (approximately 80 metres distant) is 14.5 dB(A).

For the average source noise level measurements detailed in Table 2, these noise levels at the closest
part of the eastern boundary of the subject site would be:

    •       43.6 – 14.5 = 29 dB(A) LAeq,15min;
    •       49.8 – 14.5 = 35 dB(A) LA1,15min;
    •       45.8 – 14.5 = 31 dB(A) LA10,15min.

For noise from Allstar Metal Fabrication to not be audible beyond the boundaries of the subject site the
noise from Allstar Metal Fabrication must not exceed:

        •   42 dB(A) LAeq,15min;
        •   54 dB(A) LA1,15min;
        •   44 dB(A) LA10,15min.
