Rand said that the sound level for the proposed turbines should be measured using the Lmax metric, which measures the the maximum level of a noise source, because of the language in the township’s zoning ordinance, which reads as follows: The audible sound from the wind turbine(s) shall not exceed 45 A weighted decibels, as measured at the exterior of an occupied dwelling on another lot, unless a written waiver is provided by the owner of such building.
Administrative Law Judge LauraSue Schlatter last month recommended that the Freeborn Wind farm be denied an operating permit, saying the southern Minnesota project failed to show it can meet state noise standards. Freeborn Wind’s developer, Invenergy, has objected.
This important paper has found lving close to to wind turbines "is negatively correlated with self-rated environmental quality of life and physical health quality of life." The finding is consistent with other studies cited in the paper. The authrose also found that turbine noise alone is not the only factor. Other factors may include "visual sight, vibrations, shadow flicker, sub-audible low frequency sound, or mechanisms that include individual subjective experiences and attitudes towards wind turbines." The results of the paper are posted below. The full report can be downloaded by clicking the links on this page.
Scituate selectmen voted unanimously Tuesday night to award a contract for conducting an acoustical study of the Scituate Wind turbine to Epsilon Associates as an independent consultant. The Maynard-based company has performed similar testing in Massachusetts, and other states, and has worked with the Massachusetts Department of Environmental Protection (DEP), according to Al Bangert, special projects director.
This important lecture on low frequency noise, infrasound and its effects on health by Dr Mariana Alves-Pereira was held in Ljubljana, Slovenia.
“We had no choice” : Wind Concerns Ontario on taking legal action regarding wind turbine noise reports
Several residents living near the turbine continued to report disturbances from the turbine, however, and asked town officials to agree to an independent noise compliance investigation of the turbine in an effort to collect the evidence necessary to take protective action under both the Nuisance Law and under the state’s Noise Pollution Regulation.
The council has leverage over Green Development’s actions that it can use to address the residents’ complaints, he added. “You are the landlords so you can’t say you’re not responsible. ... Everything falls on the landlord,” he said.
In its summary, and with unanimous support from relevant experts, AAT found that there were numerous recorded instances of wind turbine noise exceeding 40 dB(A) — a recognized threshold for annoyance/sleep disturbance. “Even if it is not audible, low-frequency noise and infrasound may have other effects on the human body, which are not mediated by hearing but also not fully understood,” the summary reads.
"Unwanted noise on our property, shadow flicker on our property the chance that marketability of our homes, if we decide we want to move is reduced. The potential of association from the turbines to have some ill health effects,” said Doreen Hansen of the Association Of Freeborn County landowners. “So we would like to see respectful sighting. Landowners that choose to have a turbine on their land, that's fine, but none of the ill effects should go on the land of a non-participant."
PORTSMOUTH — The combination of the noise and shadows generated by the town's wind turbine has rankled some neighbors who voiced their frustration to the Town Council during its meeting Monday.
Big Blue will now have to file a noise modeling of the installed wind turbines that indicates projected compliance with MPCA noise standards within 30 days of order, including monitoring during periods of curtailment; an on/off monitoring protocol within 60 days of order; and a completed on/off noise monitoring study within nine months of the order.
The number of complaints received for wind farm noise is significantly higher in Omagh and Fermanagh District than any other council area. According to latest statistics from DAERA, there was a total of 13 noise complaints.
A Notice of Application for Judicial Review was filed by DDOWT in the Divisional Court in Toronto on Tuesday against the Ministry of the Environment and Climate Change alleging the ministry has allowed companies promoting at least five large-scale wind projects to ignore new government guidelines with respect to limiting the amount of noise any residence in the area should have to tolerate.
“Habitat degradation is always conceived of as clear cutting, or, you know, changing the environment in a physical way. But this is an acoustic degradation of the environment,” Guralnick said. “We think it is a real conservation concern.” ...“Animals are constantly surveying their environment and making decisions based on risk. And one thing noise does is it degrades this really important sensory channel,” he said.
This important letter by acoustician Stephen Ambrose explains how two separate court decisions, one in Massachusetts and the other in Michigan, together provide clarity on what the minimum protective noise limits should be when siting industrial wind energy facilities. Mr. Ambrose's letter includes links to the two decisions as well as supporting background information. The content of the letter is shown below. The original can be downloaded from this page.
“That is something which we expect will be the subject of further study,” the AAT said. “For our purposes, it is sufficient that annoyance is produced, and it appears that it may be associated with adverse health outcomes. “An identification of the causes of that annoyance may allow it to be reduced or mitigated and adverse health outcomes to be reduced or avoided.”
The application was being sought to allow construction on the 34-wind turbine project in the former Chatham Township area to occur all night as well as on Sundays and holidays from Dec. 1 to March 31, 2018. ...Chatham-Kent's director of building services Paul Lacina said the request was denied to due to objections received from the public and inconsistency with the principles established by council within the bylaw.
