Road Traffic Noise Assessments (DA & Planning Compliance)
AACG provides road traffic noise assessment acoustic reports throughout New South Wales, assisting developers, architects, planners and project teams with development applications, planning approvals and acoustic compliance requirements.
Road traffic noise assessments are commonly required where proposed developments are located adjacent to major roads, motorways, transport corridors or other significant traffic noise sources. Acoustic reports are frequently requested as part of development applications to assess traffic noise exposure and identify any building design measures necessary to achieve acceptable acoustic outcomes.
Our consultants undertake detailed road traffic noise assessments to identify applicable planning requirements, evaluate traffic noise exposure levels and determine appropriate acoustic mitigation measures where required. We provide practical recommendations and technically robust reporting to support planning approvals, development consent requirements and informed project decision-making.
Whether supporting a residential development, apartment building, child care centre, educational facility, mixed-use development or other noise-sensitive land use, AACG delivers independent acoustic reporting aligned with applicable NSW planning requirements and project objectives.
