Low frequency noise and infrasound associated with wind turbine generator systems

"Howe Gastmeier Chapnik Limited (HGC Engineering) was retained by the Ontario Ministry of the Environment (MOE) to conduct a review of research and other information pertinent to an understanding of what is known about low frequency noise and infrasound associated with modern wind turbine generator systems. The work is divided into two main sections: a technical review, and a jurisdictional review. The technical review is intended to 'collect, review and evaluate published scientific literature and reports from the past 10 years on ... aspects of low frequency noise emissions from wind turbines to be used to build on the research previously undertaken by the Ministry and to enhance the Ministry's knowledge on the subject'. The jurisdictional review is intended to 'collect, review and evaluate information on approaches in other jurisdictions regarding requirements/limits for low frequency noise'"--P. 1.
