Annotation of standard text IEC 61400-11-ed.3.1+Amd.1-CSV :
IEC 61400-11:2012+A1:2018 presents measurement procedures that enable noise emissions of a wind turbine to be characterised. This involves using measurement methods appropriate to noise emission assessment at locations close to the machine, in order to avoid errors due to sound propagation, but far away enough to allow for the finite source size. The procedures described are different in some respects from those that would be adopted for noise assessment in community noise studies. They are intended to facilitate characterisation of wind turbine noise with respect to a range of wind speeds and directions. Standardisation of measurement procedures will also facilitate comparisons between different wind turbines. This new edition constitutes a technical revision, introducing new principles for data reduction procedures. This consolidated version consists of the third edition (2012) and its amendment 1 (2018). Therefore, no need to order amendment in addition to this publication. The contents of the corrigendum of October 2019 have been included in this copy.
