Proposed RSL Retirement Village, Cooroy - Road and Rail Noise Assessment (Revised) ==

 

3 BASELINE NOISE MONITORING
3.1 SELECTION OF MONITORING POSITION

Two attended noise monitoring positions were chosen for the purposes of the assessment.

The first monitoring position was located at the development site boundary adjacent to the Cooroy
Connection Road. The noise monitoring position has a direct line of sight to the railway and road,
hence was unobstructed from vehicular and train noise emissions. Attended noise measurements
were also completed at this location for determining maximum noise levels associated with passing
trains.

The second monitoring position was located at the rear of the development site, at the end of
Trading Post Road. The purpose of the noise monitoring was to determine to typical background
noise levels experienced by nearby residents which have a potential to be impacted by the
proposed retirement village.

The monitoring locations are depicted on Figure 1 in Appendix A and Plate 1 in Appendix C.

3.2 METHODOLOGY FOR NOISE MONITORING

Noise measurements were made using an Acoustic Research Laboratories environmental noise
logger (ARL215). The serial number and calibration information for each instrument is presented in
Table 3.1. An averaging time of 15 minutes was adopted and measurements were made over at
least a 24-hour period as detailed below. The microphone was positioned at a height of 1.2 m
above ground level and fitted with a windshield throughout the measurements.

Noise measurements for trains passing by the development site were also completed by Air Noise
Environment during a site visit on 4 July, 2007. Measurements were made using a Type 2 Svantek
943AE sound level meter (Serial Number 5163) and calibrator (Serial Number 358).

Details of the NATA certified calibrations of these instruments are presented in Table 3.2.
