摘要：

According to the wind turbine noise test method based on IEC61400-11, a wind turbine noise rated at 60KW were tested at"Small and medium-sized wind turbine field test site" in Dongying City, Shandong Province, And the collected data were analyzed, including weighted apparent power level, 1/3 frequency doubled range spectrum and pitch. This wind turbine noise emission characteristic of the study found that wind turbine running noise increase with the increase of wind speed is nonlinear, when the background noise has a linear growth with the increase of wind speed, discovered the main ingredients of this wind turbine noise was the broadband noise of 200 Hz to 2500 Hz, and the abnormal high frequency 6300 Hz audio was found by the analysis of the pitch.
