Abstract
The wind turbine sound emission and its propagation is a complex topic, which requires measurement-based investigations. Between 2018 and 2020, five extensive measurement campaigns were carried out at different locations, which lasted in total over 13 month and included the acquisition of meteorological, acoustic and turbine-specific data. Evaluating these large data sets, effective approaches for data assessment, data selection and data classification are essential. In this contribution, these approaches are explained in detail using the example of one measurement campaign and are applied investigating the refraction effects in the sound propagation of wind turbines based on measured data. Accordingly, the refraction effects are clearly visible at a distance of 500 m from the turbine. Thus, higher levels are measured in the downwind direction than in the upwind direction.
