8. Recommendations
8.1   Acoustic Barrier
A TMR acoustic barrier is recommended to be 2m high and be constructed along units 1-2 and 4-6
boundaries as nominated in Figure 7 below. The barrier shall be constructed using materials that
achieve a minimum surface density of 15kg/m². The barriers shall be constructed in accordance with
Main Roads Standard Specification MRTS15 “Noise Fences”. The barrier shall be free of gaps and
holes.
