"I have seen a lot of wind turbines and as you move further away you get a vortex effect and it sounds like six refrigerated lorries in a traffic jam.
While the industry portrays electricity-generating windmills as a benign and natural source of power, community opposition to new windmill farms is cropping up across the country - particularly in Eastern states, where there are more people fleeing urban blight to live in idyllic rural towns.
The following links are to three audio interviews conducted by the Canadian Broadcasting Company to investigate Mr. d'Entremont's claim that noise from the Pubnico Point wind plant has driven his family from its home. Editor's Note: You will need RealPlayer to listen.
The idea of windmills brings to mind bucolic Renaissance paintings of Dutch landscapes and tulip beds. But that is hardly the experience of some who have to live next to the 400-foot electricity-generating windmills being built across America's breezy plains.

Ventdubocage has posted a report from the National Academy of Medicine in France, "Le retentissement du fonctionnement des éoliennes sur la santé de l'homme" ("Repercussions of wind turbine operations on human health"). Following is a translation of a notice of the report by Dr. Chantal Gueniot in "Panorama du Médecin, 20 March 2006:
A Drefach-felindre Action Group has called on planning chiefs to turn down an application for three new turbines at Blaen Bowi windfarm.
Neighbours of Windflow Technology's prototype turbine on Gebbies Pass have begun complaining about its noise again.
Compliments of Andrew Chapman, the attached pdf files contain extensive documentation particularly with respect to the impact of wind turbines on wildlife as part of an ongoing effort to prevent the construction of the Bald Hills Wind Farm, South Gippsland, Victoria. While it has been approved by the Victorian State Government the presence in the Bald Hills area of migratory species of national and international significance that are protected by treaties with Japan and China in the Bald Hills has placed the final decision in the hands of the Federal Government. This decision is pending.
This testimony prepared and presented by Dr. Nina Pierpont is one of the first public acknowledgements of Wind Turbine Syndrome. An excerpt of Dr. Pierpont's testimony is shown below. Her full testimony can be accessed by clicking the link on this page.
Please count me among those that vehemently oppose the expansion of this crazed idea of environmentally 'friendly' energy production. Windmills are NOT environmentally friendly when implemented whis way. Please feel free to use my as an example of someone who is DIRECTLY adversely effected by these noisy, UGLY industrial generators. Editor's Note: This email was sent to Vermont State Representative Rick Hube by Tom Shea, a Searsburg property owner.
In this short, but compelling document, Dr. Nina Pierpont establishes her thesis that the noise from utility-scale wind turbines can produce health issues for people living within 1.5 miles of the turbines.
They call it the train that never arrives. It's a low, rumbling sound that goes on and on ... and on. Sometimes, in a stiff easterly, the rumbling develops into a roar, like a stormy ocean. But worst of all is the beat. An insidious, low-frequency vibration that's more a sensation than a noise. It defeats double-glazing and ear plugs, coming up through the ground, or through the floors of houses, and manifesting itself as a ripple up the spine, a thump on the chest or a throbbing in the ears. Those who feel it say it's particularly bad at night. It wakes them up or stops them getting to sleep.
Amaranth Township has scheduled the evening of March 3 and all day Saturday, March 4, as public meeting dates to review proposals for 23 wind-turbine sites.
Industrial wind turbines produce significant amounts of audible and low-frequency noise. Dr. Oguz A. Soysal, Professor and Chairman of the Dept. of Physics and Engineering at Frostburg State University in Maryland, measured sound levels over half a mile away from the Meyersdale, PA, 20-turbine wind farm. Typical audible (A-weighted) dB (decibel) levels were in the 50-60 range, and audible plus low-frequency (C-weighted) dB were in the 65-70 range. 65-70 dB is the loudness of a washing machine, vacuum cleaner, or hair dryer. A difference of 10 dB between A and C weighting represents a significant amount of low-frequency sound by World Health Organization standards.
For those who live among the towers, the consequences of the development are palpable. The construction required building new roads and widening existing ones to make room for oversize vehicles. Hundreds of workers moved into town or stayed in trailers on the job site during the summer rush. The rural landscape was transformed into an industrial setting. Where stands of poplars and fields of corn and hay covered the plateau, the smooth lines of the light gray towers and steady rotation of the rotors now define the view. And the noises changed. The unobstructed wind has always been the dominant sound on the plateau. Now, the whoosh of the wind is mixed with the hum of the machines and a mechanical whomp of the blades turning.
Windmills can create many vibrations and sounds at different frequencies depending on their size, the wind speed, whether the windmills are operating synchronously (in tandem or not); and whether the noise “beats” or throbs. The noise does not have to be loud to be disturbing. Pulsating low frequency noise can be very disturbing, especially at night when you are trying to sleep. Editor's Note: Don Bly cautions readers that while he has done his homework "I should not be quoted as being a sound or noise expert".
Now after much research, including attending a wind conference in Madison, I believe wind turbines do not fit on our ridgetops.
Proponents of the Little Equinox Mountain wind facility say it will create jobs, create tax dollars, and enhance tourism. Your readers in Manchester, Vt. might be interested to know how that argument played out when FPL Energy similarly invaded our community in 2004
