A hearing officer for the Public Service Board has recommended that Green Mountain Community Wind — the company led by Vermont renewable-energy pioneer David Blittersdorf — be found in violation of its permit for operating wind turbines on Georgia Mountain with iced blades. ...The iced blades produced unusually loud noise, said Melodie McLane.
Once it was just another cabin on a Vermont hillside. Now it’s an emblem in the debate over noise from the growing wind energy industry.
This important peer-reviewed paper examines 15 years of the authors' combined experience with wind turbine noise issues. The authors respond to the various responses by the wind industry regarding turbine noise and explain why audiologists, particularly those interested in community noise, should embrace the notion that all forms of noise, if sufficiently intense and prolonged, can be detrimental to public health. They also encourage audiologists to be sensitive to the non-auditory aspects of acoustic energy, including the dynamically modulated infrasound and low-frequency sound emitted by modern wind turbines. The background information about the paper is provided below. The link(s) to download the paper are included on this page.
A giant wind turbine in Mullavilly, County Armagh - which operated 24/7 – is now in use during working hours only, following a Court Order served after an appeal against a Noise Abatement Notice was dismissed. An out of Court settlement was agreed between village based company Rapid International and Armagh, Banbridge and Craigavon Council.
I find it interesting how several Falmouth residents continue to lambaste we neighbors of Falmouth’s wind turbines, categorizing us as “complainers.”
The issue of sound, and its effects on neighboring property owners, has become the brightest flashpoint in the wind-energy debate. And opponents of ridgeline turbines, like Rodgers, hope data from the state-funded sound-monitoring equipment will bolster their case.
Brouha and his attorney, Denise Anderson, had contended that it had been proven on the record that the company’s permit conditions were violated already, but the state has decided to order further testing in the matter, in a recent order.
On July 22, 2016, Blandine Vue from France wrote to Marie-Eve Héroux, member of the panel developing the WHO Environmental Noise Guidelines for the European Region.
The standards stipulate that interior sound be measured with windows open in the summer, closed in the winter and partly open during October and April. Opponents of large-scale wind power say allowing measurements with windows closed is a departure that violates lawmakers’ intention.
This important paper examines how wind turbine noise, particularly noise from larger turbines, falls in the lower frequency range, below 1000 and 500 Hz. This type of noise penetrates homes and creates sleep disturbance. The researchers found that, in general, the indoor noise levels of homes near turbines are higher which helps explains noise annoyance complaints. The abstract of the paper is provided below.

The board was asked to come up with the interim rules after Gov. Peter Shumlin signed a renewable energy siting bill following a special veto session in June.
The wind industry insists wind turbines are quiet. Listen for yourself. In fact, the turbines can be much louder than this!
New Brown County Board of Health member Jim Crawford, of New Denmark, has indicated a belief that some of the symptoms being reported are psychological and can be addressed via counseling. But the majority of the board said the people complaining of nausea, vertigo and sleep problems deserve to have their complaints taken seriously.
Difference of opinion and varied interpretation of county regulations consumed the discussion following the report from Hankard Environmental on the Prairie Breeze wind farm noise study, on Tuesday, July 12.
The panel voted 2-0 Thursday to remove the restrictions and require Highland to comply with a complaint resolution process and abide by noise limits in state regulations -- 50 decibels during the day and 45 decibels at night.
Ashbee wrote: “Many in Ontario and elsewhere have logged serious health complaints with proponents/operators of wind turbine projects, provincial and federal government ministries as well as wind turbine manufacturers ... As previous ministers and current Minister Philpott have been informed, the adverse effects of wind turbines are not trivial.”
Brouha’s case involves his argument that Condition 8 of the CPG has been violated “…because indoor sound levels measured at Mr. Brouha’s residence exceeded the 30 dBA criterion…based on testing conducted by his expert, Noise Pollution Clearinghouse, and, according to Mr. Brouha, confirmed by the Department’s (Department of Public Service) expert.”
Residents living half a mile from a set of four wind turbines near Milton wrote in their comments to the Public Service Board that, while they’re not trained acoustical experts, experiences at their home convinced them the existing sound limits have been set too high. Melodie and Scott McLane live three-quarters of a mile from the project, and they say certain wind conditions and low ambient noise sometimes (often at night) combine to blow disturbing levels of sound their direction.
In this open letter, Barbara Ashbee of Mulmur, Ontario, together with hundreds of other Ontarians, sent an open letter to Health Minister Jane Philpott, asking why Health Canada has not insisted wind energy corporations report citizen complaints about noise radiation.The letter, attached here, asks the minister to meet with Ms. Ashbee and representatives of citizens suffering from turbine noise radiations. An excerpt of the letter is provided below. The full letter can be accessed by clicking the links on this page.
