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

Measurement of airborne sound insulation of glazed sliding door system in CSIRO Reverberation Chambers at Clayton, VIC.

The laboratory provides a range of acoustic measurements including:

  • 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.



The laboratory provides a customised program for sound insulation measurements of glazed systems in conjunction with the Australian Window Association (AWA). Members of the AWA may nominate to be part of the program conducted at various times throughout each calendar year.

Further details of the scheme are available from the AWA or CSIRO.


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

Calibration of microphone prior to sound insulation measurements.
  • 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.
