Health Board: wind turbines are a hazard to human health
October 17th, 2014
GLENMORE, WISCONSIN, USA: “This week the Brown County Health Board went on record declaring that wind turbines “are a human health hazard“.
“Folks living in the Glenmore area near the Shirley Wind Project have been saying this for years though, and now they have the health department on their side. By state statute wind turbines can be within 1250 feet of a home. The Brown County Board of Health says that’s too close for comfort.”

The wording of the motion was as follows:
“To Declare The Industrial Wind Turbines In The Town Of Glenmore, Brown County. WI. A Human Health Hazard For All People (Residents, Workers, Visitors, And Sensitive Passersby) Who Are Exposed To Infrasound/Low Frequency Noise And Other Emissions Potentially Harmful To Human Health.”

Windfarm victims worldwide will feel vincicated by this:
In Plympton Wyoming, Ontario, Canada, complaints from windfarm victims “will lead to investigations and hefty fines. This is the first bylaw directly referencing ILFN and demanding fines of between $500 to $10,000 per day, and which may be, the bylaw states, in excess of $100,000.“
“The bylaw references charging fees to developers if ILFN causes residents problems. Common effects are, from chronic unrelenting noise: sleep disorders, hormone level disruption, increased risk of disease, diabetes, hypertension, depression, heart arrhythmias, and possibly even cancer.”

BACK IN 2013, STEPHEN AMBROSE, Board Certified Member of the Institute of Noise Control Engineering and a Full Member of the Acoustical Society of America, testified in front of the Vermont Senate Natural Resources Committee:
“Regulatory boards are now unable to protect public health and wellbeing because the wind turbine industry has substituted their own measurement and assessment procedures through international committees.
“The wind turbine acoustic standards differ dramatically from other noise sources. Wind turbines are evaluated using A- weighted sound levels by removing all low frequency and infrasound from consideration. A-weighting lowers infrasound levels by 50 dB at 20 Hz and 70 dB at 10 Hz. This promotes false statements that wind turbines do not produce infrasound.
“I have measured infrasound using a sound level meter and a microbarograph. I have experienced the adverse health effects caused by infrasound. Again, I felt miserable with a headache, nausea, loss of cognitive ability, sleep interference and interruption.
“I felt better when only a few miles away from the wind turbines’ influence.”
“I recommend that anyone who thinks wind turbines are good acoustic neighbors to do what I did. Go to a wind turbine site, live as a neighbor, and sleep in their bed when the wind blows strong.“

THE BIBLE of WINDFARM EFFECTS on NEIGHBOURS:
This is just the concluding paragraph, but there is plenty more:
“A compliant project may still cause damage to neighbours for numerous reasons:
- first, the standard only refers to dBA and thereby omits reference to ILFN;
- secondly, even with regard to audible noise, the standard refers to a maximum of 40 dBA outdoors, whereas every other form of industrial or other noise in country and city is limited to 35 dBA maximum. There is no technical basis for such an aberration, and it is clearly, (intended or not), discriminatory;
- thirdly, in quiet rural environments, even 35 dBA will be intrusive and loud, if the background level is below 25dBA, which is not uncommon.
The ear responds to the peaks of sound levels, not the averages. The wind turbine noise standards all refer only to averages, and exclude ILFN, and do not account for the human response, so cannot protect people from predictable serious harm to their health.”
