          Techniques to select wind turbine and wind farm aero acoustic noise measurements, including instrumentation standards and metrology technology, measurement set, measurement procedures, data processing, and noise source data analysis are described in this standard. Nearfield sound measurement similar to IEC 61400-11 distance and far-field sound measurement both outside and inside concerned houses or buildings are within the scope of this standard. This standard focuses on amplitude modulation noise, however, guidelines for low-frequency noise including infrasound near-field measurement are provided. IEC 61400-11 provides overall wind turbine noise measurement standards, while this standard focuses more on the aero acoustic noise of wind turbines to avoid overlap with IEC 61400-11.<br />\n

          New IEEE Standard - Active.<br />\n
          Techniques to select wind turbine and wind farm aero acoustic noise measurements, including instrumentation standards and metrology technology, measurement set, measurement procedures, data processing, and noise source data analysis are described in this standard. Nearfield sound measurement similar to IEC 61400-11 distance and far-field sound measurement both outside and inside concerned houses or buildings are within the scope of this standard. This standard focuses on amplitude modulation noise, however, guidelines for low-frequency noise including infrasound near-field measurement are provided. IEC 61400-11 provides overall wind turbine noise measurement standards, while this standard focuses more on the aero acoustic noise of wind turbines to avoid overlap with IEC 61400-11.<br />\n

The scope of measurement covers near-field sound measurement similar to IEC 61400-11 and distance and far-field sound measurement both outside and inside concerned houses or buildings.

IEC 61400-11 provides overall wind turbine noise measurement standards, while this standard focuses more on the aero acoustic noise of wind turbines to avoid overlap with IEC 61400-11. Users of this standard should also be familiar with of ANSI S1.1–1994 (R2004), Acoustical Terminology.<br />\n
          This 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 surrounding communities.
