Abstract
The most remarkable noise source of wind power plants is the rotor blades of turbines generating mainly aerodynamic broadband noise. In that noise there occurs an amplitude modulation of +- 2-3 dB, having typically a modulation frequency of about 1 Hz. Other noise sources are the various parts of the generation system, the most remarkable of which is the gearbox. The propagation of the noise from a power plant is essentially affected by, besides the geometrical attenuation, the wind conditions, the temperature profile especially in the vertical direction, and the thermal stability of the atmosphere. Above ground surface, the propagation is also affected by the height differences and the surface profile of the terrain, and the materials and the vegetation of the ground surface. The noise of wind power plants causes annoyance to a greater amount of people that could be deduced from the annoyance-noise exposure dependence of the transportation noise. This is considered to be due to the interaction of the visual and aural perceptions, and the especially disturbing properties of the noise of wind power plants, mainly due to the amplitude modulation of the noise.
