Further partners


  • Manufacturers of wind turbines – with or without drive train

           Noise and structure-borne sound emanating from the gear box will also be taken into

           account in order to develop objective criteria.



Goal of the project


  • Identification of the main parameters and thresholds for an objective assessment of turbine sound and vibration emissions taking into account turbine design, topography and distance from the place of immission.
  • Development of prognosis and simulation models for the emission and propagation of airborne sound (especially infrasound) and vibration (structure-borne sound) interacting with structures, initially for flat terrain and subsequently for complex mountainous terrain and different subsoil strengths.
  • Development of strategies for optimising wind turbines through adaptable constructive designs with a view to reducing sound and vibration emissions, this applies, for example, to the positioning of the drive train or of the tower and to shielding procedures.
  • Increasing acceptance and creation of a sound data base in terms of enviromental health and environmental psychology in order to promote an objective discussion of potential health risks of wind turbines.
