Noise Report 54 Boronia Road MCU17-0546

Allstar Metal Fabrication
Environmental Noise Level Impact Assessment of Metal Fabrication Business, 54 Boronia Road, Cootharaba      Page 3 of 17




Noise Limit Criteria

In accordance with the Noosa Plan 2006:

S53.2 Noise from the business is not audible beyond the site boundaries;

S53.3 All noise emanating plant and equipment associated with the business is enclosed or located at
least 200m from adjoining houses.


AMBIENT NOISE LEVELS, MONITORING LOCATION B

Table 1 details the range and average ambient noise levels at Monitoring Location B (eastern side of
the residence at 46 Boronia Road, Cootharaba) with the microphone elevated 1.6 metres above ground
level. The results of this ambient noise assessment are representative of the ambient noise levels at all
nearby residences, with no noise of Allstar Metal Fabrication audible at any time (noise logger located
on the opposite side of the residence to Allstar Metal Fabrication).

For details of measurement equipment, equipment settings, monitoring location and atmospheric
conditions for the weekdays and weekend, refer Appendix A, whilst Appendix B details all of the key
parameter results of the ambient noise level measurements.

With respect to noise the following should be noted:

        daytime:           0700 to 1800 hours;
        evening:           1800 to 2200 hours;
        night-time:        2200 to 0700 hours;
        ‘A’ weighted:      adjustment made by the sound level meter to the measured noise to
                            correspond to the response of the human ear. This adjustment is
                            standardised by international noise standards;
        LAeq,T:            the equivalent continuous (or approximately the ‘average’) ‘A’ weighted sound
                            pressure level for the measurement period ‘T’;
        LA1,T:             the ‘A’ weighted sound pressure level exceeded for 1% of the measurement
                            period ‘T’;
        LA10,T:            the ‘A’ weighted sound pressure level exceeded for 10% of the measurement
                            period ‘T’, which is an approximation of the ‘average of the maximum noise
                            levels’;
        LA90,T:            the ‘A’ weighted sound pressure level exceeded for 90% of the measurement
                            period ‘T’, which is an approximation of the ‘average of the minimum noise
                            levels’, which is also known as the ‘background’ noise level.
