Abstract [en]

In an extensive measurement program, with economical support from the Swedish Energy Agency, long-time measurements of meteorological effects on sound propagation from wind turbines are performed at three sites in Sweden. The measurements are performed continuously during 1-2 years. Sound propagation is studied in a 1) forest area, 2) over a water bay and 3) over heterogeneous terrain. The first two sites are located in the southern part of Sweden and the third is located in the northern part of Sweden. The meteorological conditions change over the day and the year and vary a lot depending of the terrain conditions. Mean variations of the expected sound level of 6 - 14 dBA at the imission point for different weather conditions have been found. The aim of the project is to improve the knowledge about sound propagation from wind turbines and especially over varying terrain and different weather conditions. The hub height of the studied wind turbines varies from 80-138 m. The result shall be improved sound propagation models,updated measuring requirements and methods for deriving meteorological input data for a sound propagation model.
