AMBIENT NOISE LEVEL MEASUREMENTS

Table 1 details the results of the ambient noise assessment conducted from the monitoring location on
the subject site for the daytime, evening and night-time periods – refer Figure 1 for further detail,
Appendix A for details of measurement equipment, equipment settings, calibration, etc., Appendix B
for graphical presentation of key parameters and Appendix C for atmospheric conditions.

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.
