Overview

We provide a range of services to help improve the acoustic environment in buildings, optimise the acoustic behaviour of products and measure acoustic performance.

Our standard acoustic laboratory measurements include: 

  • Airborne sound insulation of walls, floors, doors and windows
  • Impact sound insulation of floors and walls
  • Impact sound reduction of floor coverings
  • Sound absorption of materials and objects
  • Sound absorption and acoustic impedance
  • Sound power level of sources
  • Airflow resistance of acoustic materials
  • Loss factor of vibration damping materials.

CSIRO has been involved in a number of high profile acoustic test and measurement projects, including:

  • Barangaroo Development, Sydney
  • New Royal Adelaide Hospital
  • New Royal QLD Children’s Hospital
  • Sydney Harbour Tunnel
    – CSIRO tested a range of prototype silencers for insertion loss and aerodynamic noise.
  • Aircraft noise in Sydney
    • the Commonwealth Departments of Transport and Administrative Services commissioned CSIRO to conduct an acoustic evaluation to provide technical advice on the insulation of houses exposed to aircraft noise in Sydney.
  • Acoustic rating of windows
    • the Residential Window Association commissioned CSIRO to develop a national acoustic rating scheme for windows to provide ‘a level playing field’ for the window industry using a singlenumber rating scheme based on scientific testing.
