Microphone measurements in the vicinity of wind power plants: Results for the wind park in Gagel, Saxony Anhalt, Germany

This document compiles the results of a sound measurement campaign in the vicinity of a wind park to provide objective data for a quantitative characterisation of noise emission in the infrasound frequency range. Microphone measurements were carried out at a wind park near Gagel, Saxony Anhalt, Germany and were compared with results obtained with microbarometers nearby. The experimental setup, the data acquisition and the analysis are described, and narrowband and octave band spectra are calculated and depicted. Reference data are given which allow a first assessment of the noise situation.
