Low-frequency noise from large wind turbines.British Wind Energy Association
Wind turbines emit low frequency noise (LFN) and large turbines generally generate more LFN than small turbines. The dominant source of LFN is the interaction between incoming turbulence and the blades. Measurements suggest that indoor levels of LFN in dwellings typically are within recommended guide...
The new European Directive "Road map for low carbon economy to 2050" shows the way to improve the energy efficiency and the renewable sources play a fundamental role to fulfill this goal. Despite wind energy is one of the most efficiency renewable energy, the wind farms' design require an ...

In the OC5 and OC62 projects, the authors observed a persistent underprediction of the nonlinear, low-frequency responses of an offshore wind semisubmersible with many mid-fidelity engineering models, including the OpenFAST tool developed by the National Renewable Energy Laboratory. Both the low-fre...
