Wind Turbine Noise Reduction

Noise from wind farms falls into two categories: aerodynamic noise is created by the blades of a turbine swishing through the air, while mechanical noise is associated with the machinery housed in the nacelle of a turbine. As mechanical noise tends to be tonal, it is this that is most often a nuisance factor for residents living nearby. As a result, there are strict regulatory standards throughout Europe and North America, and when operators do not meet these requirements, they face potentially heavy penalties.
