Chateaugay to review Jericho Rise host community agreement in dispute over outside noise testing of wind towers

The Town Board had planned to allow a third-party firm to test the noise levels generated by the towers of the Jericho Rise Wind Farm in the area where a number of complaints have been raised. Town Supervisor Don Bilow said that the Jericho Rise’s parent company, EDP Renewables, has “stonewalled” attempts for an outside test.

Is ‘big wind’ making people sick?

Both Cindy Cobb and Sandra Wolfe from Calhan, Colo., live in the shadow of Golden-West, and blame the turbines for deteriorating health. They report dizziness, nausea, loss of sleep and headaches. They say their symptoms coincide with when the wind farm became operational in September 2015. Cobb adds lethargy and high blood pressure to the list of symptoms ...According to Wolfe, the relentless spinning causes stress and loss of sleep. She has resorted to sleeping off-site from her own property.

Sound waves

The injury created by continuous thrumming sound waves is hard to grasp for people who haven’t been exposed. Aggrieved neighbors have sought to establish, through monitoring, that the sound at their homes is excessive. The utilities and wind developers have been dismissive, characterizing complaining neighbors as cranks or hypochondriacs.

Public Service Board issues final sound standards for wind projects

The final rule keeps the daytime sound level at 42 decibels, but the board changed the allowable nighttime level from 35 decibels allowed in the draft rule to 39 decibels. The board also kept a controversial setback limit of 10 times the height of the turbine, so that a 500-foot turbine would have to be at least 5,000 feet from the nearest residence.

Public Service Board rules Georgia turbines don't require additional sound studies

About a year later, the board ruled in favor of Georgia Mountain Community Wind and determined that noise coming off the spinning turbine blades was not in excess of its state permit. But in that ruling the board said the McLanes and the Public Service Department could request additional testing if they could convince the board that the previous sound testing was not accurate.

Proposed PSB rule is not the end of wind energy in Vermont

VPIRG and REV have implied that the proposed rule will be the end of wind power in Vermont. In particular, VPIRG undertook a GIS study that showed that 0.2% of Vermont would be available for wind facilities due to the setbacks in the proposed rule. There are two problems with VPIRG’s analysis: its premise is wrong and the conclusion does not follow from its data.

Fresh approaches coming for wind farm noise

City council chief executive Paddy Clifford said in his notice of review that noise from Te Rere Hau needed to be better managed and monitored. He said there were inaccuracies in evidence given about the acoustic effects of the wind turbines at the original consent hearing, with the effects turning out to be far greater than had been predicted.

The winds of woe

Prospective neighbors of wind turbines heard all the promises:  “Quiet as a library.”  “Like a baby’s breath.”  “The same decibel level as a refrigerator.”  The more brazen wind developers claimed “you will not hear them.” Then the four hundred and fifty foot wind towers with their bus-size nacelles and three-bladed fans were built. Sixteen in Sheffield, four on Georgia Mountain, twenty-one in Lowell.  And  neighbors learned the truth.  Yes, you can hear them.  They sound like “a jet plane that never lands,” or “sneakers in a drier,” or there is a “thump thump thump” or a “whoosh whoosh whoosh” as the blade passes the tower, causing something called amplitude modulation.

Hopkinton Wind Advisory Board won’t expand areas where generators can be built

A request by wind farm developer Avangrid Renewables to expand the wind overlay zone was not agreed upon by the board, according to Jody Wentzel, vice chairman of the Hopkinton Wind Advisory Board. The board is also considering setting 24-hour decibel limits for the wind towers, different than what the Town of Parishville is considering. Parishville has opted for two 12-hour periods ranging from .25 to .45 decibels.

Altered cortical and subcortical connectivity due to infrasound administered near the hearing threshold – Evidence from fMRI

Journal.pone.0174420-infrasound_thumb The findings of this study  demonstrate that infrasound near the hearing threshold may induce changes of neural activity across several brain regions, some of which are known to be involved in auditory processing, while others are regarded as keyplayers in emotional and autonomic control. In other words, sound that is not audible can still trigger a response in the human brain.

Turbine neighbors are fed up

Councilwoman Karen Carlson, who said she receives at least two complaints about the turbines per day, visited West Log Bridge Road to see for herself what her constituents had been talking about....she could hear the noise emanating from the structures. “I can understand how it makes people crazy,” she said. “Honestly it was like this drone of a jet that just kept going.”

Rand: Critique of Noise Impact Report for NextEra's Golden West Wind Energy Center

Rand_review_epsilon-4177-goldenwest-170321_thumb NextEra's Golden West Wind Energy Center sited in El Paso County, Colorado was required under the County permit to conduct a noise impact study after the project was placed in service in October 2015. Acoustician Robert Rand was asked by residents living near the turbines to review the noise impact study as prepared by NextEra consultant, Epsilon Associates. Mr. Rand's report, included here, identified several material errors with Epsilon's report and also found that the project appears to be operating outside the noise limits permitted by the County and the State. The Golden West Wind Energy Center consists 145 1.72-megawatt GE turbines for a total installed capacity of 249.4-megawatts Mr. Rand's executive summary is provided below. The full report can be accessed by clicking the document icon on this page.
