40、u YuanDaidi Zhong*Member Emeritus7Copyright 2016 IEEE. All rights reserved.IntroductionThis introduction is not part of IEEE Std 2400-2016, IEEE Standard for Wind Turbine Aero Acoustic Noise Measure-ment Techniques.The wind turbine in a wind farm can produce amplitude modulation noise (AMN) caused b

41、y rotating airfoil self-noise, particularly trailing edge scattering noise and Doppler effects due to blade motion relative to the observer; it is also recognized as “swish” sound. The envelope of the acoustic wave appears to be blade-pass-ing frequency; therefore, it gives the impression that it is

42、 low frequency with blade-passing frequency noise. Meanwhile, the sound pressure pulsation due to blade aerodynamic loading fluctuation and blade tower inter-action characterized as low-frequency noise (LFN), including infrasound, were observed from indoor mea-surement near a wind turbine in operati

43、on. The AMN and LFN are both identified as wind turbine aero acoustic noise that has been reported as the most annoying to residents near wind farms, including such complaints as sleep disturbance, nausea, giddiness, etc. The issue becomes a larger public concern as more wind farm proj-ects are buil

44、t with modern powerful wind turbines deploying larger and longer blades. However, the current IEC 61400-11 noise measurement standard did not address this issue, especially in far-field indoor conditions. To address this issue, IEEE started a standard development project, P2400, in October 2013. Thi

45、s standard establishes standard measurement techniques and methods of analysis to quantify wind turbine and wind farm aero acoustic noise. It can be used to understand wind turbine aero acoustic noise, so-called low-frequency/infrasound and amplitude modulation noise, and potential impacts on surrou

46、nding communities. This docu-ment provides the standard measurement techniques for wind turbine aero acoustic noise, including instru-mentation selection, measurement setup, near-field and far-field outdoor and indoor post-data processing, and noise source data analysis. IEC 61400-11 has provided an

47、 overall wind-turbine noise-measurement standard, while this standard focuses more on the aero acoustic noise of wind turbines to avoid the overlap with IEC 61400-11. It is advised that users of this document are also familiar with ANSI S1.11994 (R2004) Acoustical Terminology.8Copyright 2016 IEEE. A
