Michael Creech had planned to retire at the family homestead, a two-story farmhouse among square miles of farmland east of Hope in western Vermilion County. But he said he's changed his mind ...mostly because of the noise. There are three different noises, a whooshing sound from the blades turning, a droning noise that he compares to a jet engine, and noise from the motors when the turbines change position.
Vestas recommends relative noise limits that take into account local background noise levels (where new wind turbines are sited near existing ones, already present turbine noise should not be calculated as part of the background noise).
Board of Health Chairman Joe Casna said this week that the board has taken no vote, nor acted on any motion by any member of the board, to direct the health agent to acquire a loaner meter.
"We are encouraged to see that the Court will not be a rubber stamp for DEP decisions on wind power. This is a decision that FMM finds helpful because the Court addresses the health and environmental impacts of wind power projects."
In this important ruling by the Maine Supreme Judicial Court, the court found that a proposed wind project that was accepted for review by the State prior to more restrictive nighttime sound emissions limits being adopted, would still be subject to the new sound limits. The full ruling can be accessed at the link below.
The court unanimously agreed with the groups' appeal of a ruling by the Board of Environmental Protection that backed the DEP's decision that the nighttime noise level for the windmills should be at or below 45 decibels.
The US EPA submitted comments on the Draft Environmental Impact Statement (DEIS) prepared for the Shu'luuk Wind Project proposed for the Campo Indian Reservation in San Diego County, California. An excerpt of the comments is provided below including EPA's concerns about infrasound and the potential impact on human health. The full submission can be accessed by clicking the link on this page. This project was officially withdrawn from consideration.
Unlike other forms of variable noise, however, such as railways and aircraft, it [turbine noise] can continue for very long periods at a time. The nature of the noise - a rhythmic beating or swooshing of the blades - is also disturbing. UK noise limits permit turbines to be built so close to houses that sleep impacts and associated health effects are almost inevitable.
“When PSC 128 was created in 2010 by a committee stacked with wind interested members, the scientific information about the devastating health effects of industrial wind turbines was ignored and kept from the record. They took away the power of local units of government to protect their families from the devastating impacts of industrial wind turbines.”
The Department of Environmental Protection has discarded sound data on Fairhaven's turbines obtained one night during October when one turbine was experiencing a technological error. DEP spokesman Edmund Coletta said the error caused the turbines to spin without producing power and was caught when a DEP technician was reviewing data after the test.
Underneath the two 1.5 megawatt wind turbines in Fairhaven, Massachusetts, the whirring sound is unmistakable. Yet, during State-ordered noise testing in October, the turbines were set to spin-only and not to produce electricity. Turbine noise is unmistakably louder when power is being produced. The developer, after denying any manipulation of the turbines to artificially reduce noise levels, in a letter dated February 26, the developer admits a 'mechanical failure' resulted in the turbines not operating as required. The Massachusetts Department of Environmental Protection has ordered new studies. Duration: 4 minutes 40 seconds
The wind developer for Fairhaven Wind, two industrial-scale towers built near residences, has admitted that the sound survey conducted on October 15, 2012 was tainted due to one of the turbines, while still spinning, was not producing power. The developer insists human error was the cause but claims the no intent to artificially reduce the sound levels. The State of Massachusetts has ordered the results be discarded and for further studies to be conducted.
Underneath the giant wind turbines in Fairhaven the whirring sound is unmistakable. And even in the closest neighborhood, just over one thousand feet away, you can still hear it. Residents say it's taking a toll.
Wind opponents and neighbors, however, aren't satisfied with the study, and say the noise generated by the 400-foot-tall turbines is still loud enough to disrupt the quality of life for nearby residents. ...The turbines sound like "a jet plane on the horizon." The noise isn't steady, the Nelsons say, but pulses in and out.
In this video, Cary Shineldecker of Riverton Township in Mason County MI, testifies about life inside the CMS Energy Lakewinds wind plant which includes 56 Vestas 1.8MW V100 Turbines. Each machine is 476' tall. The closest turbine is 1139 feet from his home. CMS received $73 million in federal stimulus funding for the $255 Million project. The installed cost for this wind project is $2,500/KW which is 25% higher than the national average. This is because MI must use "low wind" wind turbines due to an average 6.5M/s wind resource, far lower than Iowa's 8.5M/s resource. CMS is currently planning a new combined cycle natural gas plant of 700MW capacity with a price tag of $750 million. It will have an average capacity of nearly 700MW or 28 times more capacity than the wind plant for only $1100/KW.

Controversy over wind energy in Brown County. A proposal to amend the noise ordinance to include low- frequency noise will go before the Brown County board. That could decide the fate of future wind farm projects.
Dr. Steven Cooper, an Australian acoustician with considerable experience measuring wind turbine sound emissions, prepared this important and detailed critique of a study sponsored by the South Australia EPA on low-frequency noise. The SA EPA report insisted that infrasound emitted by wind turbines was not different from infrasound from other sources in the environment. Dr. Cooper exposes the fatal flaws in the EPA's methodology for surveying the sound. Excerpts of his critique are provided below.

The households have complained that the noise from the turbines, which have an overall height of around 100 metres, has turned their lives upside down and made their lives unbearable. The constant pulsating noise has led to sleep deprivation and is impacting on the health of those living close by.
