Posted Tue Aug 12 2008: from Fraunhofer-Gesellschaft, via EurekAlert: 'Anti-noise' silences wind turbines http://apocadocs.com/s.pl?1218544192 IWU researchers have developed an active damping system for wind turbines.... "These systems react autonomously to any change in frequency and damp the noise -- regardless of how fast the wind generator is turning," says Illgen. The key components of this system are piezo actuators. These devices convert electric current into mechanical motion and generate "negative vibrations," or a kind of anti-noise that precisely counteracts the vibrations of the wind turbine and cancels them out.
