The Institute of Acoustics has welcomed the publication by RenewableUK of research and a proposed planning condition to deal with the issue of amplitude modulation (AM) of noise from wind turbines.
Richard Perkins, Chairman of the IOA Noise Working Group, said: “This research is a significant step forward in understanding what causes amplitude modulation from a wind turbine, and how people react to it. The proposed planning condition, though, needs a period of testing and validation before it can be considered to be good practice. The IOA understands that RenewableUK will shortly be making the analysis tool publicly available on their website so that all interested parties can test the proposed condition, and the IOA will review the results later in the year. Until that time, the IOA cautions the use of the proposed planning condition.”
