Abstract:
A wind turbine noise suppression system can include a sound absorbing batting and a fabric sheet within a column of the wind turbine. The sheet can hang within the column whereas the batting can be placed in at least a bottom and top region. A vibration isolation pad at the top of the column can mitigate a megaphone effect. The pad can be combined with an isolation washer. The pad can be less than a half inch thick, whereas the isolation washer can be less than a quarter inch thick. A sound curtain can be installed at a base of the column to suppress bell resonance. The system can, for example, reduce wind turbine noise up to ninety percent.
