French Academy of Medicine warns of wind turbine noise

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:

Documentation Related to the Proposed Bald Hills Wind Farm, Victoria, Australia

Belinda_appleton_'s_statement_of_evidence_bats_thumb 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.

Noise is an Issue in Searsburg

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.

And the beat goes on . . .and on and on

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.

Health Effects of Wind Turbine Noise

Nina_pierpont__health_effects_of_wind_turbine_noise__2-4-06_thumb 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.

Powerful change in wind - Towering turbines bring income for some, clean power for state, but some say costs too high

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.

Noise Issues: Don Bly's Letter to the Windham Regional Commission

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".
