AMBIENT NOISE LEVELS

Table 1 details the results of the ambient noise levels at Monitoring Location A with the microphone
elevated 1.6 metres above ground level. The results of this ambient noise assessment would be
representative of the ambient noise levels at the adjoining residential to the south and south-east.

For details of measurement equipment, equipment settings, monitoring location and atmospheric
conditions for the weekday and weekend, refer Appendix A, whilst Appendix B details all of the 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.
