Reducing infrasound and low frequency noise from windturbine blades and rotors using ANC

摘要

The paper constitutes an application of Active Noise Control (ANC) on noise from wind turbine blades and rotors. This study aims at considering the potential of using ANC on wind turbines. To this end, a review was carried out on infrasound and low frequency noise emanating from wind turbines. The basis of human interaction with low frequency noise from wind turbines and its effects are studied, their effects on the environment, past approaches used for their reduction and the potentiality of using ANC. The performance of the system was evaluated by carrying out simulations. The results show that ANC systems are capableof attenuating infrasound and low frequency noise from wind turbines.
