Professor John Ffowcs Williams, a world acoustic expert at Cambridge University says modern very tall turbines do cause problems and guidelines fail adequately to protect the public. Nicol Stephen the Deputy First Minister for Scotland, when standing beneath a newly commissioned turbine recently, said: "It was as noisy as being below the path of a very low flying aircraft." Such a statement is highly significant when made by the Deputy First Minister who is a vigorous supporter of wind turbine energy. Of course low flying aircraft move on, unfortunately wind turbines do not.
P.E.I. has hired a consultant to review the level of noise coming from wind turbines at the new Eastern Kings Wind Farm. Some people living in the area complain the noise is keeping them up at night. One resident says he may move if the noise problem continues. “We’re going to have monitors set up right at the wind farm, another monitor probably halfway between the wind farm and the individual’s house and then we’ll have the third one at the individual’s house — outside,” Environment Minister Jamie Ballem told CBC News Wednesday. “We’ve also asked the people to record or keep a diary. So that way we can find out if it’s wind conditions, are the turbines even turning, which direction is the wind, so we can really narrow down what the issue is here.” The government has hired the consulting firm of Jacques Whitford to do the study. The final report will be presented to the government in a few weeks with any recommendations for change.
FAIRHAVEN - Residents speaking at a forum on wind power last night made a lot of noise about what kind of sound two proposed Little Bay wind turbines would produce. During a sometimes chaotic meeting in a standing-room only hall, some wanted to know why a specific wind study has not been done on the project and why turbines would be erected closer to homes than what is recommended in other studies. "We have done the studies that the town asked us to do," said Nils Boldgen of the Massachusetts Technology Collaborative, which has worked with the town on the project. "A noise study could be done." Officials also said the sound requirements would have to meet levels determined by the town's bylaw: 60 decibels at 600 feet.
Joyce Manley, who lives in the Painted Hills neighborhood near Desert Hot Springs, Calif., has been fighting nearby wind turbine projects for six years. ‘It’s like having a disco going all night long,’ she says.
Noise created by commercial-scale wind turbines has become a major concern around the world as wind power development continues to proliferate. Although the industry claims that modern turbines are quieter - even as they grow ever larger - complaints are increasing from people who live near new projects............National Wind Watch calls on the commercial wind industry to respect the people who reside in targeted development regions, to honor their right to healthy lives and peaceful enjoyment of their homes, by adopting meaningful setbacks - measured in miles, not in feet.
Noise from the new wind farm at East Point on P.E.I. is loud enough that some some residents of Elmira say it wakes them up in the middle of the night. "It's something like a washing machine when the clothes get off to one side. It goes thump, thump, thump. It's similar to that. Some people say it's like a jet engine," said Elmira resident Dwayne Bailey, who lives about one kilometre away from the turbines.
Statement from JANE DAVIS of Deeping St. Nicholas.
Ashfield-Colborne-Wawanosh Twp. council is sending a letter to the Ministry of Environment asking for an immediate response to a report on the affects of noise from wind turbines. At council's March 20 meeting, Reeve Ben Van Diepenbeek said the township still has not received a response back from Minister Laurel Broten who they met while attending a conference in Toronto in late February. Coun. Doug Miller said it was the minister, herself, who said the ministry would respond to their questions and a report by Dr. Vandenberg,
As a layperson researching what Minnesota calls a: "Wind Energy Conversion System" (WECS) or also known as a Wind Turbine, there is one issue that always rears its ugly head, "Noise". I found that Minnesota is one of the many states to specify maximum exposure levels of noise to its citizens. The Minnesota Rules Chapter 7030 describes the limiting levels of sound established on the basis of present knowledge for the preservation of public health and welfare. Within this article I will attempt to provide a logical trace of the sound limiting requirements, along with some possible "delta" areas at the County Zoning Ordinance Levels with regards to a WECS application.
almerston North City Council's noise specialist Nigel Lloyd opened his case to slash turbine numbers for the proposed Motorimu wind farm yesterday. The joint hearing by commissioners was in its second day of overtime and looks set for a couple more. There were 218 submitters on the proposal within the allowed time period, 91 of whom indicated they would like to speak on their submission. Yesterday was the opening of the council's presentation.
The first commercial wind farm planned for Michigan's Thumb will be too loud for a rural area and could result in lawsuits unless zoning rules are changed, an Okemos consultant says. Jeanette Hagen, a manager with Connecticut-based Noble Environmental Power, which plans to begin erecting 41 large windmills in Huron County's Bingham Township around July, says the consultant's study is flawed and won't stop the long-delayed project from progressing. "So many people are wanting to see these up and we're hoping to get these up and help energize the economy in the Thumb," Hagen said. The study, by E-Coustic Solutions of Okemos, cost about $3,000 and was paid for by Residents for Sound Economics and Planning, a group of Thumb residents that has been critical of the windmill project.
Wind turbines can have distressing noise effects that can degrade health and lifestyles, a resource consent hearing was told yesterday. Tararua Aokautere Guardians called a number of witnesses to support its submission against the proposed 127 turbine Motorimu Wind Farm planned for the Tararua Ranges behind Linton and Tokomaru. Sound energy expert David Bennett said there is "extensive evidence, both internationally and within New Zealand," that wind turbines can have distressing noise effects which can degrade health and lifestyles, and hence property values". If Motorimu proceeded as planned, Kahuterawa Valley would be particularly affected, while Linton-Tokomaru area residents would also be affected, particularly in easterly winds and conditions of temperature inversion. Dr Bennett and noise expert Richard Thorne both criticised the recognised noise Standard for wind farms, NZS6808. Dr Bennett said the standard's deficiencies contributed to division between developers who say they meet the standards and residents who feel noise distress. Mr Thorne said noise research showed 10 percent of exposed people were "highly annoyed" by traffic noise at 60dBA, while the same degree of annoyance occurred at 36dBA for wind turbine noise.
ARKPORT - The Hornellsville town board discussed the benefits and drawbacks of a wind farm at its meeting night. With the Steuben County towns of Howard and Hartsville set to vote this week on wind laws developed for these communities, Hornellsville is still in the talking phase. Hornellsville still has a moratorium on wind farm development in place. One opponent of Howard's wind farm - Howard resident Eric Hosmer- was on hand at the meeting. He spoke about the impact of the turbines- usually between 400-450 feet tall - particularly the sound the windmills make.
A farmer who says wind turbines have ruined his family's life, has lent his support to Northumberland protesters fighting 28 on their own doorstep. Julian Davis, whose Lincolnshire farm stands less than a kilometre from a wind farm says the constant thump and hum the turbines emit has driven him and wife Jane to distraction. At 100 metres high even they would be dwarfed by the structures proposed for Middlemoor, near South Charlton, north of Alnwick. His advice is simple - fight the plan now because it is too late once they are built.
FREEDOM - The town's Board of Appeals has rejected plans to erect three electricity generating wind turbines on Beaver Ridge. After four weeks of hearings, the board late Thursday found Portland-based Competitive Energy Service's turbines would not meet town standards for noise, said Addison Chase, chairman of the appeals board. The board also ruled that CES must post bonding for future demolition of the turbines. The planning Board approved CES's application in December. Planning board members agreed with a study that determined the turbines would not exceed the 45 decibel limit set in the ordinance. The vote was 3 to 0. Francis Walker abstained from the vote. Appeals board members determined that the study had been based on faulty ambient, or background, noise levels, Chase said. The planning board had required CES to post a bond for the construction phase, but Chase said the ordinance clearly requires the company to bond for future demolition as well. CES can appeal Thursday's decision to Waldo County Superior Court or start the process over again with the Planning Board.
It is believed a twisted blade was to blame for excess noise being reported at the Bradworthy wind farm site.Torridge district council was made aware of the problem, and parish councillors were told at their last meeting it had finally been resolved. Residents had complained of excess noise coming from the site at Forestmoor which is home to North Devon’s first set of wind turbines. Torridge said the environmental protection team was contacted by the parish council and one of its officers visited the site confirming noise levels were higher than normal. The council got in touch with turbine operators, Energie Kontor, and carried out follow-up visits. Both the district and parish councils say noise levels have now returned to normal.
On a sunny spring morning, Deeping St Nicholas provides a perfect snapshot of English country life. The only buildings that break the flat horizon of the Lincolnshire fens are silver-grey church spires and neat red-brick farmhouses, around which are clustered barns and silos. A covey of wood pigeons clap their wings as they take off from the black, loamy, fertile soil striped with green lines of oilseed rape. And then you hear it. "Whoompf ... whoompf ... whoompf ..." Like the sound of an approaching train that never comes, the thumps that break the still air are not overpoweringly loud - at about 65 decibels, they're the level of a lorry going by at 30 miles an hour 100 yards away. But what is so menacing is the regularity and the scope of the noise, which feels like a giant heartbeat shaking the earth. When you see the culprits - the eight mammoth wind turbines installed just outside Deeping St Nicholas last May - you're actually surprised that the noise isn't louder. These aren't the little propellers that David Cameron nails to his roof to warm his cocoa and heat his children's baths. They're veritable behemoths - 100 metres high, as tall as Big Ben's tower.
FAIRFIELD — If wind turbines are built in this northeastern Herkimer County town, one family may be forced to move. Lisa Sementilli's 11-year-old daughter Alisha has central auditory processing disorder, which means Alisha hears fine but can't concentrate when she is around background noise. Doctors have suggested that Alisha live at least one-and-a-half miles from any wind turbine, but Hard Scrabble Wind Farm towers planned in Fairfield would be less than half a mile away, Lisa Sementilli said. "If they come, I have to move," she said. "I'm not going to put my daughter in any harm."
Dr. Robyn Phipps provided testimony before the Joint Commissioners in the Matter of the Moturimu Wind Farm Application. Dr. Phipps' evidence consists of four areas of concern:
RESIDENTS said "no" to proposals for 16 more wind turbines in Deeping St Nicholas. Villagers spoke out at a special meeting of Deeping St Nicholas Parish Council, which was called to give a reaction to proposals at Church Farm. The proposals, made by Spanish renewable energy giant Iberdrola, would add to the existing eight turbines, taking the number in the village to 24. Jane Davis, who has faced sleepless nights due to low frequency noise from the turbines, said: "They don't really understand how these large wind turbines interact with each other in a flat landscape. The research just hasn't been done.
