From Table C.1 the highest predicted rail noise level is 82 dBA Lmax in the retirement community
allotments and 80 dBA Lmax outside the aged care building. All other locations have lower levels
of noise exposure. Based on the predicted noise levels the MP4.4 Noise Categories in Table C.1
for rail noise are up to Noise Category 3.
The predicted Lmax noise levels comply with the noise limits of 87 dBA (1m from the facade) and
84 dBA (free-field) from Section 4.2.3 and Section 4.1, and therefore no noise barriers are
required. However, a noise barrier has previously been proposed (refer Figure 6.1) and this can
be included in the noise calculations.
The predicted single event Lmax noise levels with the proposed noise barrier are listed in Table
D.1. From Table D.1 the highest predicted rail noise level is 78 dBA Lmax in the retirement
community allotments and 77 dBA Lmax outside the aged care building. All other locations have
lower levels of noise exposure. Based on the predicted noise levels the MP4.4 Noise Categories
in Table D.1 for rail noise are up to Noise Category 2.
A review of building construction requirements associated with the predicted MP4.4 noise
categories is included in Section 8.
