Development of an approach to controlling the impact of amplitude modulation in wind turbine noise: exposure-response research, application and implementation

摘要

WSP - Parsons Brinckerhoff was commissioned by the UK Government Department of Energy and Climate Change to undertake a review of research into the effects of and response to the acoustic character of wind turbine noise known as amplitude modulation (AM), or more specifically an increased level of modulation of aerodynamic noise as perceived at neighbouring residential dwellings, with a view to securing protection, where it might be justified within the planning regime. This paper describes how the literature review was undertaken and the key findings on the state of knowledge of the effects of AM on people, and the response relationships that have been identified. It highlights the gaps in the knowledge base and the risks of bias in the studies reviewed. The paper also describes potential methods to control AM, the recommended penalty scheme method, how this might be applied in practice, and feedback received following publication of the main research report.
