Wind turbine acoustics

This chapter presents some of the most important issues related to wind turbine acoustics. After a short background, an introduction to acoustics follows where we defi ne the most important parameters that are met in the chapter. Next, the noise generation mechanisms are discussed from a physical point of view. Some aspects related to noise propagation and their perception are presented. A major part of the chapter consists of a review of the prediction models with different level of complexity together with experimental methods that are often used for wind turbine aeroacoustics. Finally, a short list of noise reduction strategies is also given.
