  • `Anti-noise` silences wind turbines

    If wind energy converters are located anywhere near a residential area, they must never become too noisy even in high winds. Most such power units try to go easy on their neighbors' ears, but even the most careful design cannot prevent noise from arising at times: One source is the motion of the rotor blades, another is the cogwheels that produce vibrations in the gearbox. These are relayed to ...

  • Canada to Study Wind Turbine Noise and Health

    Health Canada, in collaboration with Statistics Canada, will conduct a research study that will explore the relationship between wind turbine noise and health effects reported by, and objectively measured in, people living near wind power developments.

  • Silencing wind turbines - active damping system developed to cut noise

    Wind power is one of the world's fastest growing energy technologies and proponents say the electricity generated by wind turbines is clean and environmentally friendly. But opponents are quick to point out a number of drawbacks including noise pollution. Due to the humming noises they emit, these turbines operate partially to keep residents happy. Partial use, however, cuts power output. A group ...

  • Are motorways the best spot for wind turbines?

    Wind turbine noise can be detected at low levels, even when it is heard alongside motorway traffic noise, a study finds. It is possible for louder motorways to drown out turbine noise, however. The participants in this listening experiment could easily detect wind turbine noise, but only once they knew it was present in recordings of environmental noise. Public annoyance with wind turbine noise ...

  • New wind turbines to replace old in Germany

    Many of Germany’s wind turbine projects began in the late 1990’s and are now faced with declining output, thanks to wear and tear. Now with newer technologies surpassing old, and larger available wind turbines, it makes sense to start replacing older systems with new. As a result, Nordex will be replacing 16 legacy wind turbines with 9 newer models by the end of the year, at the ...

  • Offshore wind farm construction noise can displace harbour porpoises

    Noise caused by construction of Germany’s first offshore wind farm caused significant habitat disturbance for harbour porpoises, according to a recent study. Its results suggest that porpoises avoided areas up to 20 kilometres from the noise source during construction of the wind farm’s foundations. Development of offshore wind farms plays a major role in the shift towards renewable ...
