Sycamore Street, East Malvern Victoria

Product requirements

  • High sound absorption at low frequency (60Hz to 120Hz)
  • Suitable for outdoor applications
  • Water repellent facing
  • Must not grow mould when exposed to rain

Product features

  • Low frequency tonal ‘humming’ noise impacting nearby residents
  • Initial remediation using brick walls
  • Additional treatment is required to comply with environmental noise regulations

Megasorber P100G-RG

P100G-RG 100mm acoustic polyester panel with water repellent Soundmesh® G8 facing (Grey).

Product advice

  • Add noise barriers to block out the direct noise path to residential areas
  • Line the noise barrier and all walls with Megasorber P100 to absorb transformer noise
  • Line concrete footing areas with Megasorber P100 to further increase sound absorption.
