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

 

It should be noted that the Department of Main Roads references recommended internal noise
levels specified in AS 2107 Acoustics — Recommended Design Sound Levels and Reverberation
Times. For houses and apartments near major roads, a 30 to 40 dB(A) and 35 to 45 dB(A) internal
Leg Noise criteria is required for sleeping and living areas, respectively.

Tables 5.5 to 5.6 below specifies the noise reduction requirements for achieving the relevant
internal noise criteria. Noise reduction requirements are typically different for rail and road noise
given the difference in noise parameters and internal noise criteria used in the the assessment of
potential impacts. Tables 5.5 and 5.6 present worst-case noise reduction requirements only, after
comparison of the road and rail noise predictions.
