Objective The objective of this project is to develop a noise prediction tool to support the development of new quiet rotor blades and to validate the code. This requires the cooperation of scientists all over Europe and the collection of the measured data available from various wind turbines located in several European countries. Nowadays, siting of wind turbines often meets the problem of rising public resistance. The following two points account for this trend : 1. The number of available ecomonic sites providing annual wind speeds which are high enough, is decreasing. Therefore new sites must be located closer to populated areas. 2 Furthermore the aim is to use the remaining sites more economically which supports the trend to build larger wind tubines (500kW-3MW) with higher tip speed velocities, i.e. higher than 100m/s. The interaction of the rotor blades with the air produces sounds which are dependant of the flow conditions and the geometry of the rotor blades. The higher the tip speed velocity, the louder the noise. People living close to wind turbines could get annoyed by the noise, therefore new blade geometries must be developed in order to reduce the emitted noise of wind turbines. This requires noise prediction codes. Current methods are mainly based on simple theoretical or semi-empirical formulas. Within new methods the empirical parts should be replaced step by step.
