Sound Propagation From Wind Turbines - A comparison of measurements and calculations at the forest site Ryningsnäs.
Today wind power developers are exploring the possibilities of establishing wind turbines in forest areas, therefore improved sound prediction models for complex terrains are valuable. The Swedish model used today is only applicable for hard flat ground without any vegetation, and is not adjustable to any meteorological parameters except the wind speed.
