Study on Noise Characteristics of Concentrated Wind Energy Turbine

Different types of wind turbine generate different noises in normal condition. A comparison of noises from local spot by means of modern acoustic measurement is carried out between 300W concentrated wind energy turbine and ordinary wind energy turbine, and conclusion is that the noises from the concentrated wind energy turbine are lower than that from the ordinary one. Besides, the main noises are from turbine blades and increase with the wind speed on both turbines.
