Dick Bowdler, a member of the IOU who is not involved in the study, said noise level limits and health effects should have been taken into account as part of the new guidance. The acoustics consultant pointed out that this is not only essential for planning a wind farm, but for compensation if it is built.
In his latest report Dr Hanning said: "Industrial wind turbines emit a unique impulsive noise pattern, described as thumping, swooshing and rumbling. It contains a large element of low frequency noise which travels further and penetrates buildings more easily than high frequency sound.
The developer carried out its own noise risk assessment but the council has appointed an independent noise expert to assess the risk of noise pollution at the site. NoPilrow spokesman David Maund said: "It is good Sedgemoor is taking the issue of noise seriously.
Although the full results from a measurement exercise are not expected until Friday, preliminary findings indicate that noise levels from some turbines are slightly above the limits set within the planning consent, in certain wind conditions.
A provocative investigation claims thousands of people are falling sick because they live near them. The symptoms they claim to have suffered may vary – including dizziness; increased blood pressure and depression – but the theme remains the same.
The school had been warned when it was granted planning permission in 2009 that if noise were to become an issue the turbine may have to be decommissioned. Specialist engineers had worked with the school over a period of about eight months to try to reduce noise, but modifying the blade tips and even shortening the blades themselves had little effect.
This useful analysis examines many of the key issues raised before the Courts in the United Kingdom regarding wind turbine noise nuisance cases. An excerpt of the paper is provided below. The full report can be accessed by clicking on the link at the bottom of this page.
This important document critiques the ETSU-R-97 environmental assessment of noise from wind turbines in the United Kingdom. The ETSU-R-97 was written by a Noise Working Group (NWG) set up in 1995 by the Department of Trade and Industry through ETSU (the Energy Technology Support Unit). The noise policy is still in effect today and followed by wind developers outside of the United Kingdom.
This brief filed by sleep expert, Dr. Christopher Hanning, reviews the potential consequences of wind turbine noise and, in particular, its effect on sleep and health and to make recommendations with regard to minimum setback distances. Dr. Hanning considers whether, in the absence of new national guidance should there be minimum or recommended separation distances between commercial scale wind developments and residential properties and other sensitive developments?”
The study released Tuesday by the Massachusetts Department of Environmental Protection shows that the Wind One industrial turbine in the Cape Cod town of Falmouth produces noise louder than the state allows. The report marks the first time the state has recommended a shut-off of a wind turbine.
Residents in Palgrave say work to decrease the noise from the village community centre's controversial wind turbine has not worked. The turbine was switched off for two months while the community centre worked to reduce the noise emitted by the 24-metre high turbine.
North Devon Council has received more than 20 complaints from residents living around Fullabrook wind farm, between Barnstaple and Ilfracombe. It is operational, but noise monitoring cannot be carried out until the wind farm is officially commissioned. That was supposed to happen in October, but has been repeatedly delayed.
He said the noise from the 66-megawatt farm, which is yet to operate at capacity after extensive testing since it was opened last October, has left him a mental wreck, unable to sleep because of the "thudding" noise and liable to burst into tears for no reason. Noise testing at the site is not due to start until next month.
Nick Williams said he and other residents were suffering increased stress levels because of delays in officially commissioning the site. The delay meant that complaints about the noise could not be officially investigated. Until the wind farm is officially commissioned, the environmental health team at North Devon Council said it was not legally allowed to carry out noise checks.
"This has been worse than fighting cancer," said Jane. "With cancer, all of the professionals are on your side and in the first year of this, in 2006/07, we felt we were up against a brick wall. In 2007 a noise report came out and it said the problems we were having did exist.
Mr Harrison added: "Further, at least until recently when their own recordings and monitoring have finally forced the defendants to acknowledge they are causing problems, their approach has been to try and shoot the messenger".
Details from the dossiers come as a series of new studies conclude that living near to wind turbines can increase levels of sleep disruption and stress-related conditions. One review of the scientific evidence written by environmental health consultants who work on behalf of the wind energy industry stated that noise from wind turbines was "associated with some reported health effects".
Plans for a green energy project at a farm near Chichester involving the construction of two wind turbines more than 100ft high have been thrown out. Councillors on the district's southern area development control committee voted 8-1 to refuse planning permission on the grounds of inadequate information about the noise implications of the scheme.
Several residents feel they are trapped living with the noise because if they tried to move house few people would be interested in buying a property next to a wind turbine. Nick Williams lives at Fullabrook itself with six of the turbines near his house. He claimed the wind farm had destroyed the area he lives in as well as his life.
Instances of excessive noise of wind turbines at a family home located 950 meters from the Hadyard Hill Wind Power Plant. The Hadyard Hill wind facility is located in the Carrick district of South Ayrshire in Scotland. The project was commissioned in March 2006 and consists of fifty-two 2.3 megawatt wind turbines.
