Infraschall von Windenergieanlagen: Realität oder Mythos?

Wind turbines are radiating sound at extremely low levels in the infrasound range (below 20 Hz).This sound is far below the detection threshold und thus far below levels which can cause any diseases. Measurements on a turbine in the megawatt class at the DEWI Test Site showed levels of 58 dB at a distance of 100 m to the turbine in the one-third octave band level at 10 Hz [2], which means more than 30 dB below the hearing threshold at this frequency.
