Library filed under Noise
A group opposing wind turbines in Vermont has taken what its organizers say is an unprecedented step by filing a public records request with several legislators who are reviewing new sound limits for future wind-energy projects. Two of the legislators have already turned over all the requested documents. Six have not.
David Dardi, who lives near the turbine and who had been keeping track of the turbine noise, said the turbine continued to “disrupt the sleep and adversely impact the lives and health of both my neighbors and myself.” ...Selectman Karen Canfield said she would support to curtail the use of the turbine from 11 p.m. to 6 a.m. in the summer.
The rule proposed by the Public Utility Commission sets a 42-decibel limit for wind turbines during the day, when measured 100 feet from the outside of neighboring homes, and a 39-decibel limit at night. The Legislative Committee on Administrative Rules chose to extend the deadline for a vote on the rule.
The committee’s charge is rather to ask a fairly narrow set of questions about a rule, Benning said, including whether it meets the intent of the legislation that enabled it, whether the rule is arbitrary, and whether its potential economic effects are adequately described. Benning said he’s satisfied the rule meets all these criteria.
Residents in Scituate who live near a wind turbine claim it's ruining the quality of their lives. Many say the wind turbine is causing nausea, dizziness, ringing in ears and sleep deprivation and they want it shut down for good.
Acting Town Administrator Al Bangert said they agreed to shut down the turbine during the hours of 11 p.m. to 6 a.m. when the wind blows from the southwest. ...Officials said since then, complaints have dropped more than 60 percent. But there has been a financial cost as well. Bangert is forecasting a financial loss of more than $100,000 per year whenever the blades power down.
FINLAND. Aunio Group Oy from Oulu has developed a device for measuring and recording infrasound produced by wind turbines. The measurement equipment can be used to produce research data for investigating the characteristics of infrasound and where it spreads, and to analyze any health problems it may cause. The infrasound produced by wind turbines differs from infra-sounds occurring in nature; according to measurements the infrasound produced by wind turbines is a clear signal - distinguishable from ambient noise in the environment. This paper describes the method of evaluating the Anuio Group's device and the results. The full paper can be accessed by clicking the links on this page.
In 2015, the town conducted a study and found that complaints from residents were most common during the summer between 11 p.m. and 6 a.m., when the wind was less than 10 mph and blowing in a southwest direction. During the last two summers, between June and October, the town has shut down the turbine when those conditions are met.
It has been revealed that a wind turbine which has caused years of "anguish and distress" for residents in Castlewellan has breached required noise limits at a nearby residential property. ...A major factor that has been troubling residents in the area since the turbine was erected is the noise emitted.
Now with a slew of new wind farms planned around his town of Hawkesdale, 300km west of Melbourne, and impending changes to Victorian state planning policy, Mr Lewis is seriously pondering his future. “Everyone thinks these things are great, but they’re not the ones living beside them and getting woken up at night,” he said.
Residents of Savoy have the opportunity to save themselves from this same peril (most likely worse, with five much larger turbines), during the upcoming turbine hearing on Sept. 24. One hearing. One night. Make the right decision.
Huffman told commissioners the problems were worst when wind speeds were low, particularly between 6 metres per second and 10m per second. She backed the city council's position, that there should be an 8m per second threshold before the turbines kick in at night. She also said subjective assessment was a legitimate way to monitor noise.
State regulators sided with the McLanes, generally, and operators will now have to use meteorological data to stop the blades before ice forms. The project's original state permit said the turbines would have to be paused only after ice is detected. (The PUC Order can be found by clicking the document icon to the right.)
Councilman Wayne Rogers called on his fellow Town Board members to explore modifications to the town law adopted prior to the construction of the Jericho Rise project to address some of the problems that have arisen since the wind farm began operation at the end of last year.
In November 2014, Health Canada released the results of its $2.1 million “Wind Turbine Noise and Health Study.” Despite public anouncements from Health Canada that the raw data originating from the Study would be made available, the data continues to be inaccessible making it impossible to validate the conclusions drawn by Health Canada researchers. For example, HC found high levels of annoyance but concluded no association to turbine noise.
David Janes of rural Toronto, South Dakota, said he and his late wife had built a retirement home on their South Dakota farm site 17 years ago. ...“But when the turbines are running, I can’t hear the birds. All I hear is swoosh, swoosh swoosh, like a jet plane engine.”
More research will be required to determine safe set back distances from wind turbines, a leading scientist said in Tullamore last week. Dr Mariana Alves-Pereira was speaking to the Tribune after addressing a seminar on the effects of the turbines on animal and human health.
The question of whether wind turbines are physically capable of producing the adverse reactions claimed is unresolved. However, it is now scientifically demonstrated by Swedish researchers that amplitude-modulated low-frequency wind turbine noise can directly cause sleep disturbance, even in young fit people taking part in its research study.
Windfarms louder than birdsong will be forced to shut down under new regulations due to take effect early next year. ...But Mr Naughten said the regulations included a "zero-tolerance" approach to shadow flicker and nuisance sound.
It's all likely to prove academic, since LCAR is almost certain to vote down the rules sometime after leaf-peeping season. At that point, the PSB would have to resume work on a new set of rules. Given the fact that the board and the Scott administration take a dim view of ridgeline wind and most legislators are in favor of renewable energy including wind, it's going to be very tricky to find a set of rules acceptable to all parties.
