Road and motorway projects bring together many engineering and scientific disciplines, and noise is frequently the issue that shapes alignment, drives design, and decides community acceptance. Traffic noise affects homes, schools and sensitive receivers along the entire length of a corridor, governing everything from barrier placement to pavement selection — while the construction phase brings its own intense noise and vibration from earthworks, piling and plant, often close to occupied properties and running around the clock. Matrix Acoustics understands how to work as an integral part of a larger design team, with staff who have worked on some of the largest road projects in Australia and New Zealand and know what it takes to deliver road projects large or small. That experience spans the full lifecycle — predicting operational traffic noise at receivers, assessing it against the policies that govern each state, and preparing the assessments that underpin planning approval and design development.

Early input is where the value lies. Matrix Acoustics provides advice during route selection and design — modelling alignment options, testing the effect of noise barriers, mounding and low-noise pavements, and optimising mitigation to protect receivers without over-building costly treatments. A comprehensive monitoring and modelling suite, combined with thorough knowledge of the federal, state and local legislation that bears on every road project, keeps noise and vibration within criteria through construction and provides the defensible record that protects both the project and the community relationship. Engage Matrix Acoustics to bring an acoustics group with comprehensive knowledge and skill into your project or design team — delivering road projects that meet their acoustic obligations from feasibility through to operation.
