Measurement of wind turbine construction noise at Horns Rev II

Open Access Report 2008

Institut fur technische und angewandte Physik GmbH

ITAP
The construction of the Horns Rev II wind farm is accompanied by a marine mammal monitoring programme. As a part of that study, underwater noise was measured on the installation of pile J2. During pile driving, a maximum peak level of 195 dB and a maximum SEL of 176 dB were observed at 720 m distance from the pile. At 2300 m distance, respective values were 180 dB for the peak level and 164 dB for the SEL (all sound levels re 1 μPa). The spectral maximum of the pile driving noise was in the frequency range 80 – 200 Hz.
