Wind turbines to produce electricity on a large scale – “wind farms” – are currently being proposed for parts of Tug Hill. Large-scale wind farms are a relatively new occurrence in the Northeast, and since they are new there are many questions that do not have clear answers.
Wind power is a relatively new generator of electricity in Sweden. Legislation and regulation regarding noise from wind turbines in Sweden have been discussed. Eja Pedersen at Halmstad University has at the request of the Swedish Environmental Protection Agency prepared this report as a base for further discussions on regulation and guidelines on noise from wind turbines in Sweden. The report reviews the present knowledge on perception and annoyance of noise from wind turbines in residential areas as well as in recreational areas. It also summarizes regulations in some European countries. The author Eja Pedersen is responsible for the content of the report.

Kelly Alexander believed that windpower would be a good energy source. He was told the machines were not noisy. No one told him about the blade flicker that shines even through closed blinds or the low frequency noise that penetrates his home with doors and windows tightly closed and storm windows installed. Recently, the turbine owner visited Kelly and asked what he could do to help the situation. He said, “Stop lying about these turbines. Tell people the truth.”
The development of commercial wind power that is currently fashionable is potentially misguided, ineffective and neither environmentally nor socially benign; but it is the right of citizens of rural areas to enjoy both clean and safe energy generation and an unspoiled countryside.
Lincoln Township in Wisconsin sent a survey to its residents to help assess the impacts of 22 turbines installed by Wisconsin Public Service Corporation (WPSC) and Madison Gas and Electric (MG&E), which went online in June 1999. A summary of the survey comments received is provided in the attached document. After the wind turbines went online, the Lincoln Township Board of Supervisors approved a moratorium on new turbine construction.
Written in 2000 by the Country Guardian, the UK's leading 'action group', this report addresses comprehensively wind issues in the UK. As one of the first papers of its kind, it is generally viewed as a 'classic' and 'required reading' for those interested in becoming thoroughly familiar with the diverse impacts of industrial wind.
The document critically reviews the adverse effects of community noise, including interference with communication, noise-induced hearing loss, annoyance responses, and effects on sleep, the cardiovascular and psychophysiological systems, performance, productivity, and social behavior. Noise measures or indices based only on energy summation are not enough for the characterization of most noise environments. This is particularly true when concerned with health assessment and predictions. It is equally important to measure and display the maximum values of the noise fluctuations, preferably combined with a measure of the number of noise events, and to assess whether the noise includes a large proportion of low frequency components.
This paper, presented at the Windpower ’87 Conference & Exposition in San Francisco by N.D. Kelley, a physicist at the Solar Energy Research Institute in Golden, Colorado validates the fact that turbines (both upwind and downwind) produce low-frequency sound emissions that can negatively impact humans within their homes. Although modern wind turbines are different from those studied in 1987, the research is significant in that it demonstrates the need to test for low-frequency sound emissions and to do so inside buildings.
