Wind energy generation systems - Part 11-2: Measurement of wind turbine noise characteristics in receptor position


To establish standardized techniques and methods applicable for measurement of noise immission. The technical specification focuses on compiling methods for quantification of wind turbine noise in one or a set of documents in order to ensure a common reference taking the characteristics of wind turbine operational parameters into account.
Quantification of the acoustics phenomena at the receiver position includes the following topics:
• amplitude modulation;
• low frequency noise;
• impulsivity;
• tonality;
• sound pressure levels;
• rating level, which includes adjustments for the above-mentioned phenomena, should be suggested if possible.
