Abstract
Noise produced by the blades of a wind turbine electric generator is reduced by creating randomly varied serrations on the trailing edge of the blade, thereby creating vortices of varying size, energy, and distance from the trailing edge. This configuration creates vortices that tend to cancel one another while avoiding the creation of adjacent, mutually reinforcing vortices.
