Noise emission from wind turbines in wake

Improving the noise prediction to optimise wind farms

Funded project: EUDP/ERP

Acoustic measurements will be performed at various degrees of wake using several measuring techniques. The results will be compared with aerodynamic measurements to enhance knowledge of wind turbine noise emission at low, medium and high frequencies. The objective is to improve noise prediction and thus optimise wind farms.
