Patent ID: 8878377

Claim:
A wind turbine comprising: a wind turbine tower having a tower wall, a wind turbine nacelle positioned on top of said tower, and a noise reducer for reducing noise emission from said tower, said noise reducer comprising: a plurality of discrete circumferentially-spaced beams, each beam being formed as an elongated strengthening member and generally extending in a longitudinal direction of said tower, and a plurality of dampers associated with each beam, wherein said dampers are arranged relative to the beams to form at least a first set of circumferentially spaced dampers and a second set of circumferentially spaced dampers longitudinally spaced from the first set of dampers, and wherein said dampers are arranged between said tower wall and said beams so that relative movement between said tower wall and said beams results in dissipation of energy via said dampers in order to reduce noise emission.
