Scope

This standard provides measurement procedures to characterize the characteristics of noise emissions from wind turbines. The measurement procedure includes measurement methods suitable for evaluating noise radiation at measurement locations near the wind turbine, in order to avoid errors caused by sound propagation, while ensuring a sufficient measurement distance relative to the limited sound source size. The measurement procedures given in this standard are different from those used in regional environmental noise studies in some respects, and are convenient for describing the noise characteristics of wind turbines within a certain range of wind speed and wind direction. Standardization of measurement procedures also facilitates performance comparisons between different wind turbines. The measurement procedure provides a consistent method for accurately measuring the noise emission characteristics of a single wind turbine. Measurement procedures include: ? Location of acoustic measurement locations; ? Requirements for collection of acoustic, meteorological and wind turbine operation-related data; ? Analysis of collected data, content of test reports; ? Definition of specific noise radiation parameters, and environmental assessment Definitions of relevant terms used when This standard is not limited to a specific capacity or model of wind turbines. The procedures given in this standard can be used to fully describe the noise radiation of wind turbines. Measurement methods for small wind turbines are described in Appendix F.
