Proposed ASL Retirement Village, Cooroy — Road and Rail Noise Assessment

 

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) and Larson Davis sound meter. 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.
