Australia’s biggest noise assessment under way

SLR Consulting Australia Pty Ltd has been appointed to undertake Australia’s largest noise assessment.

The work is being undertaken by SLR’s Acoustics & Vibration, and covers the 33,357 kilometres of Queensland’s highways, freeways and State-controlled roads.

The purpose is to assist with the Queensland Development Code (QDC) in determining construction requirements for new dwellings, or upgrades to existing dwellings, located near a designated Transport Noise Corridor.

The proposed noise model will cover approximately 20,000 square kilometres, and will be built from Light Detection and Ranging (LiDAR) data where available. LiDAR and other surveys will be adopted to provide buildings and existing noise barriers that will also be included within the assessment to understand the screening benefits that these objects provide.

SLR can predict environmental noise impacts by mapping city-wide noise, which is a combined process of geographical information systems (GIS) and acoustic analysis. It involves producing a 3D model that covers a large study area; and using this model to calculate the noise impact to the surrounding population.

This is a critical tool used by all levels of government to understand noise impacts and to create strategic plans, procedures and policies to mitigate any undesirable effects on the community.
