Are wind turbines noisy?
The evolution of wind farm technology over the past decade has rendered mechanical noise from turbines almost undetectable with the main sound being the aerodynamic swoosh of the blades passing the tower. There are strict guidelines on wind turbines and noise emissions to ensure the protection of residential amenity. These are contained in the scientifically informed ETSU Working Group guidelines 1996 and must be followed by wind farm developers, as referenced in national planning policy for renewables. The best advice for any doubter is to go and hear for yourself!
