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.

The following information was submitted to the Potter County Commissioners of Potter County Pennsylvania during their regular meeting on September 25, 2008. Martha Young appeared before the Commissioners to request a 1-mile setback from non-participating landowner property lines. Prior to her submission, Ms. Young searched for documentation to defend her request. The materials presented before the County board were the result of this search. Links to her supporting documents can be found below.

This talk was presented at the annual conference of the Canadian Acoustics Association.

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.

This letter was sent to the Steuben County (NY) IDA in response to UPC Wind's decision to hire outside contractors and construction workers to erect the Cohocton Wind facility.

These comments were submitted by IWA/WindAction.org to the Maine Department of Environmental Protection in regard to continuing noise problems at the Mars Hill wind energy facility in Mars Hill, ME.
