Abstract

Chapter 5 has described the approaches for predicting the noise emission due to the different noise mechanisms introduced in Chapter 4. It became clear that current prediction codes can give an overall estimate of the noise of a blade section or a whole wind turbine, but often fail to predict correct spectral shapes. However, since the mechanisms of noise generation are partly well understood there will be a possibility of deducing ways to reduce the noise even if it is not possible to compute it correctly. Based on theoretical findings and extensive experimental work, this chapter shows how a noise reduction may be accomplished.
