Confusing and contradictory results from Health Canada wind turbine noise study

Health Canada recently released a summary of results from its study of Wind Turbine Noise and Health.  Findings were confusing and apparently contradictory.  From the Health Canada report:

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.
The following was found to be statistically associated with increasing levels of WTN:
  • annoyance towards several wind turbine features (i.e. noise, shadow flicker, blinking lights, vibrations, and visual impacts).
Further down in the report:
5.3 Annoyance and Health
  • 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.
Huh? WTN exposure IS NOT associated with a bunch of bad health effects but WTN annoyance (caused by WTN exposure) IS associated with the same bunch of bad health effects and then some.

Any guesses how this will be received by the wind industry and its media supporters and by the people who have to live near wind turbines?

Here's the angry reaction from North American Platform Against Wind Power (NA-PAW).

Rona Ambrose is an awesome Health minister. Take your liberal crap somewhere else. You don't belong on bloggingtories.

There is no way to sugarcoat this study, for opponents of rapacious wind companies, especially in Ont, this is a huge setback. Peer reviewed comments and criticism from analytical observers have already begun, but the damage in terms of public perception is massive. Wind enthusiasts, national media and Ont Liberals will quote this source for years, mentioning only the headline summary. This was the danger from the start, hoping that a federal ministry would rescue Ont victims from the actions of their own provincial authorities. This study will help Ont to complete its industrial wind development in rural Ont over the next 3 years.

Martin, I think you're right.

Anonymous, you're a moron.

We need to examine the methodology of the study. Who actually funded it? Who participated?

Many studies are created specifically for propaganda purposes--mainly to grab headlines and to be quoted over and over again for years.

Wait until the Ontario wind towers begin to experience bearing failure. No reasonably priced, long-lasting bearings actually exist. The bearings begin to contribute to increasing vibration, and finally seize or catch fire. Who is going to pay the replacement costs?
