Using an aerodynamic structure designed to reduce sound pressure, acoustic louvres provide attenuation (noise reduction) while maintaining the required airflow.

  • Typically used in building openings
  • Reduce airborne noise, while allowing continued airflow and ventilation
  • Can be used as acoustic screens around mechanical plants where equipment requires airflow
  • Often found in boiler and plantrooms in residential areas or on rooftops
  • Industrial applications include power stations, cooling towers, chemical treatment plants

 

Tested in laboratory facilities at SRL in Suffolk, Sound Planning supplies and installs acoustic louvres for heating, ventilation and air conditioning applications in plantrooms. A Sound Reduction Index (SRI) for each louvre type can be published upon request.
