HEALTH CANADA NOISE STUDY A MISSED OPPORTUNITY TO FIND THE TRUTH
Wind Concerns Ontario advises results summary and public pamphlet be withdrawn
November 25, 2014
On November 6, 2014, Health Canada released its long-awaited results of the $2.1-million, publicly funded Wind Turbine Noise and Health Study. Only, it didn’t: what was released in a whirlwind public relations effort was a summaryof the study results—no data was presented, nor was there a full formal report, or a publication that had undergone the promised “peer” review, by scientists.
Wind Concerns Ontario immediately convened an expert panel to review the documents available (the summary plus a PowerPoint presentation, and basic study details available on the government website) and has produced a summary report of their comments. The panel consisted of several university professors with expertise in physics and acoustics, as well as an epidemiologist, and a health researcher.
The unanimous conclusion of the expert panel is that the study design was flawed; even so, there are clear findings of a relationship between wind turbine noise and adverse health effects.
Key findings from the review panel:
- Study summary was released prematurely, without a full report, expected peer review, supporting data or analysis
- Study design was to raise questions but Health Canada concludes inappropriately there is “no association” between turbine noise and adverse health effects; however, the study does find significant correlation between turbine noise and annoyance (an established adverse health effect)—these statements contradict
- Population sample used included people who were getting a direct benefit from wind power development including money
- A significant number of addresses were found to have vacant homes or houses that had been demolished—the reasons for this were not explored
- Work on infrasound and low frequency noise is completely inadequate, say acoustics experts. One hour averages were used (in summer, the season of low wind); also industry-sourced estimates of yearly averages were used in place of actual in-home noise measurement
- Numerous biases and other errors affect the credibility of some of the study results, as presented in the summary
Wind Concerns Ontario sent a letter today to the Minister of Health, the Honourable Rona Ambrose, together with the summary of our review panel comments, and a series of recommendations.
We recommend that:
- Health Canada should remove the summary findings from the Health Canada website in their current version
- Health Canada should release the final report only after it has gone through the normal peer-review process and been accepted for publication in a recognized academic journal
- Health Canada should return to the study areas and present the study findings in a series of public meetings, as befitting a publicly-funded research project
- Health Canada should rescind the “pamphlet” in its current form and if such a publication is deemed necessary, remove the claims about the “comprehensive” nature of the study, and further, affix the disclaimer more prominently.
