Abstract

Abstract: This paper discusses various noise generation mechanisms in wind turbines and potential noise reduction techniques. Special emphasis has been laid on reviewing aerodynamic noise sources and recent advances in mitigation of aerodynamic noise. Several studies on the effect of wind turbine noise on human health have linked wind turbine noise with annoyance and sleep disturbance. Thus, there is a need to reduce these noise emissions which can be achieved by targeting the specific noise sources. Techniques for mitigation of trailing edge noise, tip noise and leading-edge inflow noise have been discussed along with recent developments.
