Underwater noise of operating wind turbines
Author: | Denmark, Noise, Videos
As a turbine operates, vibrations inside the nacelle (the housing that contains the generator, gearbox, and other parts) are transmitted down the main shaft of the wind turbine and into its foundation. These vibrations then propagate into the water column and seafloor. Mechanical noise generated by offshore turbines is concentrated at low frequencies below 1kHz, generally below 700 Hz.
Bockstigen-Valar, Sweden
Underwater recording taken less than 50 m from a 500 kW turbine operating at the Bockstigen-Valar offshore wind farm (Baltic Sea, Sweden). Sounds were recorded at a water depth of 10 m. Sound credits: Aarhus University, National Centre for Energy and Environment.
Samsoe, Denmark
Underwater recording taken less than 50 m from a 2.3 MW turbine operating at the Samsoe offshore wind farm, Kattegat, Denmark. Sounds were recorded at a water depth of 12 m.
Vindeby, Denmark
Underwater recording taken less than 50 m from a 450 kW turbine operating at the Vindeby offshore wind farm (Western Baltic Sea, Denmark). Sounds were recorded at a water depth of 4 m.
