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.

Dr, Kenneth Jaffe's response to the health and safety content of a June 2006 presentation by the NY State Department of State (DOS) in Delware County, NY.

The DOS presentation, which included a discussion of the impact of industrial turbine projects on communities and individuals, is intended to guide local officials in the process of writing regulations. Dr. Jaffe's response addresses what he believes are substantive misstatements, mischaracterizations, biased emphasis and faulty data contained in the DOS presentation.

In late February 2009 the Minnesota Department of Health (MDH) received a request from the Office of Energy Security (OES) in the Minnesota Department of Commerce, for a “white paper” evaluating possible health effects associated with low frequency vibrations and sound arising from large wind energy conversion systems (LWECS). MDH agreed to evaluate health impacts from wind turbine noise and low frequency vibrations. In discussion with OES, MDH also proposed to examine experiences and policies of other states and countries. Below are the Introduction and Conclusions of the white paper released in May 2009.

On December 10, 2009, Attorney Rufus Brown made this filing to the Maine Board of Environmental Protection in the appeal of the Record Hill Wind Project. ...As part of this filing, Attorney Brown submits newly discovered evidence of correspondence between Dora Mills, M.D., Director of the Maine Center for Disease Control ("MCDC") and the Maine DEP, which he states suggests "the review input from MCDC in the Record Hill permitting process was tainted with a political agenda rather than being from an objective evaluation for the protection of public health."

Infrasonic sounds are generated internally in the body (by respiration, heartbeat, coughing, etc) and by external sources, such as air conditioning systems, inside vehicles, some industrial processes and, now becoming increasingly prevalent, wind turbines. It is widely assumed that infrasound presented at an amplitude below what is audible has no influence on the ear. In this review, we consider possible ways that low frequency sounds, at levels that may or may not be heard, could influence the function of the ear.

Richard James is a noise control consultant and acoustical consultant with E-Coustic Solutions in Michigan. In his testimony before the Tazewell County Zoning Board of Appeals in IL, Mr. James addresses the noise study conducted by Horizon Wind for the Rail Splitter wind energy proposal. His testimony can be accessed in full by clicking on the link below and reading from page 22 of the .pdf file. Mr. James' testimony is informative and compelling.

In this important ruling by the Maine Supreme Judicial Court, the court found that a proposed wind project that was accepted for review by the State prior to more restrictive nighttime sound emissions limits being adopted, would still be subject to the new sound limits. The full ruling can be accessed at the link below.

This paper, prepared by community noise experts George Kamperman and Richard R. James, was presented at the 2008 International Noise Conference held in Dearborn, Michigan. The abstract of the paper appears below. The full body of the report can be accessed by clicking on the link below.

Abstract of a paper to be presented before the NOISE-CON 2008 conference Dearborn, Michigan 2008 July 28-31

This report, prepared by Acoustics and Noise Control expert Richard D. Horonjeff, explains how turbine noise differs from other types of noises within a community. The information was submitted to the Wisconsin Public Service Commission. An excerpt of the report is provided below.
