The Ontario government took almost 1½ years to respond to a freedom of information act regarding wind turbine noise emissions and the impact on the public. Despite claims that there were over 300 pages collected, a scant 26 pages were released and many of those pages are heavily redacted. But what was revealed was clear evidence that Ministry of Environment Provincial Officers knew of the adverse health effects of wind turbine noise years ago.

Mark and Kate Harris of Mars Hill, ME provided this letter to the residents of Roxbury, ME in hopes the voters would make an informed decision before agreeing to permit industrial turbines on their ridgelines.

At its monthly meeting held Tuesday, March 3, 2009, the Medical Staff of Northern Maine Medical Center unanimously approved the release of the following statement:

In this short, but compelling document, Dr. Nina Pierpont establishes her thesis that the noise from utility-scale wind turbines can produce health issues for people living within 1.5 miles of the turbines.

Attorney Edward S. Marion submitted this letter to Wisconsin's State Health Officer and Administrator, Dr. Seth Foldy. The letter, prepared on behalf of Brown County Citizens for Responsible Wind Energy, Inc., provides the Wisconsin Department of Public Health ('DPH') with evidence that wind turbine noise is a threat to human health and asks the DPH to conduct a formal epidemiological study of the health effects of wind turbine noise from existing wind farms in Wisconsin.

Dr. Daniel Shepherd was invited by the Ohariu Preservation Society in New Zealand to provide an evaluation of the impact of turbine noise on health and well-being. The report specifically references the proposed Mill Creek wind energy facility proposed to be built on rural land northwest of Wellington, New Zealand in the Makara and Ohariu valleys. His full report can be accessed by clicking on the link at the bottom of this page. The conclusions of his report are shown below.

These comments were submitted to Health Canada in reference to the design of the Health Canada Wind Turbine Noise and Health Study and to inform the Health Canada study team and others about the serious harm that has occurred to a family exposed to an industrial wind energy project.

This paper on Infrasound and Low Frequency Noise Dose Responses, was presented at the Inter-Noise 2007 conference held in Istanbul, Turkey August 28-31, 2007. The authors are Mariana Alves-Pereira and Nuno A. A. Castelo Branco of the Erisa-Universidade Lusofona, Lisbon, Portugal and the Center of Human Performance, Alverca, Portugal.

Wind turbines emit low frequency noise (LFN) and large turbines generally generate more LFN than small turbines. The dominant source of LFN is the interaction between incoming turbulence and the blades. Measurements suggest that indoor levels of LFN in dwellings typically are within recommended guideline values, provided that the outdoor level does not exceed corresponding guidelines for facade exposure. Three cross-sectional questionnaire studies show that annoyance from wind turbine noise is related to the immission level, but several explanations other than low frequency noise are probable. A statistically significant association between noise levels and self-reported sleep disturbance was found in two of the three studies.
