Contrary to popular belief wind farms are not noisy. You can hold a normal conversation at the base of a modern wind turbine while it is operating. Wind turbines only emit noise while they are operating. At low wind speeds the sound of the blades may be heard over the normal background noise if you are very close to the wind turbine. In stronger winds the background noise of the wind itself will completely mask the sound of the wind turbine even if you are standing right next to it. Nevertheless, noise impacts need to be carefully analysed during the planning of a wind farm to protect the amenity of nearby residences.
