Environmental Traffic and Rail Noise Level Impact Assessment for Proposed Residential Unit Development,
54 Elm Street and 5 Pearl Street, Cooroy                                                                    Page 13 of 36



Ground Floor Building Facade Noise Levels

At monitoring location A the rail noise levels are, relative to the requirements of PO42:

    •    54.9 + 2.5 (facade correction) = 57.4 dB(A) LAeq,24h; and
    •    75.2 + 2.5 (facade correction) = 77.7 dB(A) single event maximum rail passby noise.

The above monitoring location A rail noise levels comply with the noise limits of LAeq,24H 65 dB(A) and
single event maximum rail passby noise limit of 87 dB(A), as required by PO42.

The closest building facades to the railway line will be setback from the Elm Street boundary 6 metres,
compared to the microphone which was set back 7.6 metres. This difference of 1.6 + 1 (distance that
the noise limit applies from the facade) = 2.6 metres would account for an increase in rail noise level at
the closest facade of approximately:

    •    0.6 dB(A) single event maximum;
    •    0.3 dB(A) LAeq,24H.

These adjustments to the above rail noise levels will still result in compliance with the facade noise
criteria.

First Floor Balconies

For this proposed development there are no proposed first floor external living areas and therefore
PO44 is not applicable.

First Floor Facades

As for the ground floor the first floor facades of habitable rooms complies with the facade corrected
noise limit criteria of LAeq,24H 65 dB(A) and single event maximum rail passby noise limit of 87 dB(A).

Measured Noise Levels

For details of the measurement equipment, equipment settings, calibration, monitoring location and
atmospheric conditions, refer Appendix A. Appendix B contains all of the detailed results of the noise
level measurements.

From Appendix B, the following noise levels should be noted for monitoring location A (microphone
elevated 1.6 metres):

Wednesday 2 June:
• LA10,18h = 58.8 dB(A)
• LA90,8h (10 pm to 6 am) = 29.1 dB(A)
• LA90,18h (6 am to midnight) = 43.6 dB(A)

Thursday 3 June:
• LA10,18h = 60.2 dB(A)
• LA90,8h (10 pm to 6 am) = 33.0 dB(A)
• LA90,18h (6 am to midnight) = 45.8 dB(A)

Average:
• LA10,18h = 59.5 dB(A)
• LA90,8h (10 pm to 6 am) = 31.1 dB(A)
• LA90,18h (6 am to midnight) = 44.7 dB(A)
