Transport for NSW released two updated documents in April 2025: the Road Noise Criteria Guideline and the Road Noise Mitigation Guideline. The criteria guideline supersedes Practice Notes I and III of the 2001 Environmental Noise Management Manual, and the Mitigation Guideline supersedes RMS 14.584 and Practice Notes (iv), (iv-a) and (iv-c).
