Abstract
A system and method for reducing audible tonality of a wind turbine caused by vibrations generated by the drivetrain assembly thereof includes a plurality of damping elements mounted at a plurality of locations on an inner surface of a tower of the wind turbine. The plurality of locations have vibration levels above a predetermined threshold. Thus, during operation of the wind turbine, the damping elements are configured to damp vibrations of the tower so as to reduce noise generated thereby.
