Ontario anti-wind groups along with International groups, react strongly with anger to the Health Canada wind turbine noise study, knowing that projects will be exponentially promoted and sanctified worldwide, via this 2 million dollar, taxpayer funded, fraudulent study North American Platform Against Wind Energy NAPAW more responses to be released in the coming days
from the Health Canada Study
"The WTS(Wind Turbine Sound) signal has a fundamental around 0.4 to 0.9 Hz with a number of harmonics at higher frequencies. In some cases these harmonics are readily measured at distances up to 10 km and confirmed to originate from wind turbines by comparing to operational data logs."
(also see Noise Monitoring in the Vicinity of the Waterloo Wind Farm, note the distance of impacts and acoustic emissions extended out further than 8km.)
Self-reported and objectively measured health indicators among a sample of Canadians living within the vicinity of industrial wind turbines Author: Michaud, David; Keith, Stephen; et al.
This is the detailed description of the methodology used for the Health Canada/Statistics Canada “Wind Turbine Noise and Health Study”, the preliminary results of which are summarized at www.hc-sc.gc.ca/ewh-semt/noise-bruit/turbine-eoliennes/summary-resume-eng.php.
From the summary of results:
The following were not found to be associated with WTN exposure:
- self-reported sleep (e.g., general disturbance, use of sleep medication, diagnosed sleep disorders);
- self-reported illnesses (e.g., dizziness, tinnitus, prevalence of frequent migraines and headaches) and chronic health conditions (e.g., heart disease, high blood pressure and diabetes); and
- self-reported perceived stress and quality of life.
Statistically significant exposure-response relationships were found between increasing WTN levels and the prevalence of reporting high annoyance. These associations were found with annoyance due to noise, vibrations, blinking lights, shadow and visual impacts from wind turbines. In all cases, annoyance increased with increasing exposure to WTN [wind turbine noise] levels. …
- WTN annoyance was found to be statistically related to several self-reported health effects including, but not limited to, blood pressure, migraines, tinnitus, dizziness, scores on the PSQI, and perceived stress.
- WTN annoyance was found to be statistically related to measured hair cortisol, systolic and diastolic blood pressure.
- The above associations for self-reported and measured health endpoints were not dependent on the particular levels of noise, or particular distances from the turbines, and were also observed in many cases for road traffic noise annoyance.
- Although Health Canada has no way of knowing whether these conditions may have either pre-dated, and/or are possibly exacerbated by, exposure to wind turbines, the findings support a potential link between long term high annoyance and health.
- Findings suggest that health and well-being effects may be partially related to activities that influence community annoyance, over and above exposure to wind turbines.
