    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wind turbine sound; atmospheric effects; outdoor sound propagation; refraction;

    Sammanfattning : Wind turbines have grown both in size and number in the past decades. The taller turbines has made it possible to place them in forest areas which is fortunate for a country like Sweden with lots of forest. An issue with wind turbines is the sound they produce. The sound mainly comes from the rotor blades when they pass through the air. LÄS MER
