Wind turbine noise research needs to be current, WCO to acoustics journal
In the January edition of respected publication Sound & Vibration, is an article “Health Effects from Wind Turbine Low Frequency Noise & Infrasound,” published by four authors billed as :”very experienced independent investigators.”
The debate about adverse health claims has “raged for at least a decade,” the authors write, “and is now at an impasse.”
“Permitting authorities for new projects must evaluate adverse health effect claims presented as proven factual data by opposition forces, countered by project advocates who state that no physical link to health effects has ever been demonstrated”.
The lead author, George Hessler of Virginia, USA, says that all four authors “do not doubt for a moment the sincerity and suffering of some residents close to wind farms and other low-frequency sources…this is the reason all four would like to conduct, contribute or participate in some studies that would shed some light on this issue.”
“It must also be said,” Hessler continues, “that it is human nature to exaggerate grievances …”

Responses are being developed by various individuals, including colleagues involved in acoustics, and citizen groups, which we will publish when available.
Wind Concerns Ontario sent a letter to the editor expressing concern that although the word “health” is in the article title, and is the focus of the paper, not one of the four authors has any medical expertise. Moreover, WCO said, the methodology proposed by the authors fails to “include current directions of research on the rapidly changing understanding of wind turbine noise.”
“Based on the reports of the impact of wind turbines on the people living among the many Ontario projects,” WCO president Jane Wilson wrote, “we know that the emissions from wind turbines are challenging existing methodologies and analysis paradigms used by acousticians. The range of sound pressure waves emitted by wind turbines are multi-dimensional; a full understanding of the issue can come only from acousticians who are willing to move outside of existing procedures and investigate complaints without preconceived notions of answers when working on the topic.
“It is not clear that the authors of the article were willing to do this.”
Wind Concerns suggested to the Editor, and the authors, that a good starting point is to “assume that people’s complaints are valid”; we also referred to the work done in Australia by Steven Cooper. As well, reliance on A-weighted noise measurement is no longer adequate to really assess the type of noise emissions produced by industrial-scale wind turbines.
