Abstract:
The invention relates to a wind turbine having a wind turbine tower having a tower wall, a wind turbine nacelle positioned on top of the tower and noise reducer for reducing noise emission from the tower. The noise reducer including a beam formed as an elongated strengthening member and one or more dampers, where the dampers are arranged between the tower wall and the beam, the dampers being arranged so that relative movement between the tower wall and the beam results in dissipation of energy via the dampers in order to reduce noise emission. The invention further relates to a method for reducing noise emission from a wind turbine tower.
