7.2.2         Noise Model Verification
To verify the road traffic noise model, the LA10, 18hour noise levels were modelled and compared to the
measured levels as presented in Table 22. As the noise monitor was in a free-field location, the predicted
noise level is also shown as free-field.

Table 22: Comparison of Measured and Predicted Road Traffic Noise Levels

      Measured L A10, 18 hour        Predicted L A10, 18 hour        Required Correction

                 74.5                          74.7                           0


The modelled level is within the allowable tolerance of 2 dB(A) of the measured level, therefore no
correction is required to the model.

7.3              Predicted Road Traffic Noise Levels
Modelling was conducted to determine road traffic noise levels at the development in the 10 year planning
horizon. The predicted future noise levels consider the 2037 traffic volumes.
Table 23 presents the road traffic noise QDC noise category results for the residential development. Single
point receiver results are shown in Appendix D.
