The wind turbine amplitude modulation assessment methodology developed by the IoA AM Working Group is now being followed by many acoustics practitioners around the world as it represents a unique way to evaluate AM at the blade passing frequency, and within specific frequency bands. This is crucial for minimising false identifications of wind turbine AM caused by variation of noise from other sources.
Review of the evidence on the response to amplitude modulation (AM) from wind turbines, with recommendations on control through the use of a planning condition. This follows on from the work of the UK Institute of Acoustics AM Working Group but unfortunately it is not the end of the story. The industry is still waiting for clarifications on the outcome of this latter piece of work and robust guidance as to how it should be implemented. The IoA Wind Turbine Noise Working Group, chaired by our very own Malcolm Hayes, is looking into this…..
