At-property noise treatment
We understand noise can be a source of disruption to local communities during the construction and operation of major road projects. To minimise the impact of our project on local residents, we are delivering at-property noise treatment to eligible properties. Noise treatment refers to architectural acoustic measures which aim to improve the sound resistance of properties, such as window and door upgrades.
We have developed a Noise Insulation Program which outlines the criteria and process for delivering noise treatment to affected properties as part of the project.
Providing at-property treatment is a complex process and involves a number of different steps. To learn more, see our fact sheet.
We are starting the process of delivering noise treatment before the project is approved so residents benefit from reduced noise as early as possible.
