In the present study, the brain’s response towards near- and supra-threshold infrasound (IS) stimulation (sound frequency < 20 Hz) was investigated under resting-state fMRI conditions. The study involved two consecutive sessions. In the first session, 14 healthy participants underwent a hearing threshold—as well as a categorical loudness scaling measurement in which the individual loudness perception for IS was assessed across different sound pressure levels (SPL). In the second session, these participants underwent three resting-state acquisitions, one without auditory stimulation (no-tone), one with a monaurally presented 12-Hz IS tone (near-threshold) and one with a similar tone above the individual hearing threshold corresponding to a ‘medium loud’ hearing sensation (supra-threshold). Data analysis mainly focused on local connectivity measures by means of regional homogeneity (ReHo), but also involved independent component analysis (ICA) to investigate inter-regional connectivity. ReHo analysis revealed significantly higher local connectivity in right superior temporal gyrus (STG) adjacent to primary auditory cortex, in anterior cingulate cortex (ACC) and, when allowing smaller cluster sizes, also in the right amygdala (rAmyg) during the near-threshold, compared to both the supra-threshold and the no-tone condition. Additional independent component analysis (ICA) revealed large-scale changes of functional connectivity, reflected in a stronger activation of the right amygdala (rAmyg) in the opposite contrast (no-tone > near-threshold) as well as the right superior frontal gyrus (rSFG) during the near-threshold condition. In summary, this study is the first to 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. These findings thus allow us to speculate on how continuous exposure to (sub-)liminal IS could exert a pathogenic influence on the organism, yet further (especially longitudinal) studies are required in order to substantialize these findings.
Ontario has had years to respond to the knowledge that industrial wind turbines are exceeding noise limits. Regulations that the wind industry lobbied for.
In Huron-Bruce county residents continue to battle government to enforce existing regulations to protect and preserve health from intrusive noise of industrial wind turbines. The document below is just one example of many submitted to Ontario from adversely impacted residents:
The pressure continues to mount on the MOECC (Ministry of Environment and Climate Change). The turbines are emitting noise above regulated limits with tonal qualities. Ontario on their own admission and as on the public record- will use the ‘law’ to enforce protections. Do the right thing.
SHUT DOWN THE TURBINES NOW!
Tests Find Some Huron Bruce Turbines Exceed Noise Regulations
APRIL 12, 2017 4:18PM
The MPP for Huron Bruce has called on the province to shut down all industrial wind turbines that fail to comply with noise regulations.
Lisa Thompson says test results released April 7 indicate that the noise levels of turbines near two Huron Bruce residences exceed Ministry of Environment noise guidelines.
The results also acknowledged the possibility that tonal noises are being produced.
However, instead of agreeing to shut down the turbines, Environment Minister Glen Murray claimed the law is being enforced and complaints are being dealt with quickly.
“It has taken two years get these results. The next round of testing could take at least another year and a half,” says Thompson. “I don’t know what this minister thinks quick means, but suffering for three and a half years before anything gets done doesn’t sound quick to me.”
“The Black and Stachura families as well as other families across Ontario have been suffering for far too long from the impacts of IWTs which were built too close to their homes.” said Thompson. “The Minister needs to acknowledge the test results and once and for all do right by the people of Ontario affected by industrial wind turbines.”
She calls on the Minister to acknowledge the test results, and do the right thing.
The following is a letter to the Standing Committee on the Green Energy and Economy Act in back in April, 2009. It could have been written a month ago. Clearly the “Economy” target of the Liberals Act took precedence over health and safety as billions have been funneled out of the tax coffers to the owners of these projects. Thousands of complaints have been suppressed. Untold number of families have been impacted. Most irreparably.
“The windmills started up at the end of November/early December 2008 and it was only after they started them up full time that we started having problems. They were so loud we could not sleep. It was aggravating and exhausting. The one closest to us is 456 metres behind us to the west and the next is just less than 700 metres to the east. We can hear them equally well and they cause terrible noise…

The Schmidts of Kincardine in Ontario left their home in 2009 when debilitating health symptoms occurred after the wind turbines of an Enbridge project became operational. They are currently pressuring the Ministry of the Environment and Climate Change (MOECC) to undertake noise testing in a full sound spectrum including infrasound (inaudible) measurements.

Couple seeks help on wind turbine concerns.
Kincardine | by Craig Power
Kincardine residents want new tests done on Enbridge project.
A Kincardine couple is seeking Council support in their quest to have the Ministry of the Environment and Climate Change to investigate noise emissions from the Enbridge Wind turbines on Concession 6.
Norma and Ron Schmidt have had to move from their home due to health related issues they say are associated with infrasound from the nearby wind turbines.
Rachel Thompson, spokesperson for the Central Bruce-Grey Wind Concerns Group, says the project began in 2009 and they still don’t know if Enbridge is in compliance.
So far the Ministry has only done testing on the ‘audible’ noise emissions but they have not yet tested the ‘inaudible’ or ‘infrasound’ emissions which are known to cause adverse heath effects.
A noise modelling report conducted by Valcoustics Canada Incorporated showed an asterisk beside 6 properties within what they refer to as ‘ground zero’ for noise emissions, with the Schmidt home among them.
Thompson says “the report also stated that we cannot be certain that these 6 homes will not fall within the safe range of audible noise.”
At the April 5th meeting, Kincardine Council voted to support the Schmidt’s letter of request for further investigation by the Ministry of the Environment and Climate Change.
The pressure is being applied to the Owen Sound Office of the MOE with hope that testing will be conducted and answers reached.

To the editor:
You’ve heard that wind turbines are no louder than refrigerators at 40 decibels? That measurement is taken a foot or two away from the bottom of the refrigerator.
If 40 decibels is acceptable to you, then maybe refrigerators should be installed on your night stand next to your bed. Please make sure the refrigerator is set to turn on and off, on and off every two seconds to simulate the wind turbine blade’s movement. Do you really think that two-second intermittent noise all night long will lull you to sleep?
The scientific studies referred to by wind energy companies are often wind energy-funded studies. And when recent studies from many independent researchers are published that comment on audible noise, pulsation/vibration, and shadow flicker affecting nearby residents, the wind faction is quick to dismiss, trivialize, debunk, and simply ignore that information.
Michigan State University has been promoting sample zoning for wind energy systems that was highly permissive toward wind development and darn near hostile to neighbors of wind turbines. The animosity created in communities with unsafe wind development favoring wind developers may take years to disappear.
It’s a brand new ball game because, on March 6, MSU released its new wind energy sample zoning regulations. MSU researchers don’t condone prohibiting turbines. They condone safe setbacks.
The study informs the uninformed about wind development and reasonable land use regulations. These new recommendations are extremely important and confirm all of the things so many people in Michigan have worked so hard for.
Here are some highlights of the MSU recommendations:
Sound Level — On-site use wind energy systems shall not exceed 40 dB(A) at the property line closest to the wind energy system. This sound pressure level may be briefly exceeded during short term events such as utility outages and/or severe wind storms.
One MSU recommendation is a turbine setback of 2,500 feet from the property line of any parcel which is not receiving compensation for the Utility Grid Wind Energy System.
And, to show how wind energy is losing its grip in Michigan, here is a recent straw poll: In Ingersoll Township, Michigan (just south of Midland), board officials took a poll of 88 people at their March 22 board meeting. Results?
• 75 against wind development in township
• 3 for wind development in township
• 10 undecided
The money a community can make and the money a large landholder can make certainly is important. But, it’s the only bullet the pro wind faction has. However, to allow so many large landholders a financial gain is to throw the neighbors of wind turbines under the bus.

“3.3 Motion sickness from oscillations
International ISO standard 9996:2000 defines motion sickness from exposure to actual or perceived oscillatory motion; “motion sickness is a commonly experienced and sometimes severe but reversible (i. e. physiological) disorder specifically associated with exposure to actual or perceived oscillatory motion in the frequency range 0,1 to 1 Hz. One or more of a constellation of symptoms (with or without frank vomiting) may affect the sufferer. ”……
Blade pass frequencies observed in spectrogram analysis at homes near the vicinity of the Golden West Wind Facility fall within 0.2 to 0.85 Hz, within the range associated to motion sickness.”
Preliminary Field Report
Independent Infrasonic Investigations:
Vicinity of Golden West Wind Facility, El Paso County, CO
By Robert W. Rand, ASA, INCE
Rand Acoustics, Boulder
January 29, 2016
Differential acoustic pressure measurements were acquired and logged at three homes in the vicinity of the Golden West Wind Facility in El Paso County, Colorado during December 2015 and January 2016. A week of data was analyzed for each of the three homes and daily spectrograms produced which are attached. Each day’s data consisted of approximately 4.3 million differential pressure samples with a week comprised of some 30.5 million samples.
Preliminary investigation confirmed the presence of recurring acoustic pressure oscillations at 0.2 to 0.85 Hz (the “blade pass frequency” or BPF) which are associated to the Golden West wind turbine rotations. At times multiple oscillation frequencies were observed, consistent with multiple turbines operating at different rotation rates. Oscillations appeared to be more pronounced when the turbines are more upwind rather than downwind. Neighbors reported they are mostly downwind due to turbine location relative to home location and for the prevailing winds in the region.
Typical BPF total acoustic power were computed for example portions of the differential pressure data sets. Crest factors (the ratio of RMS to peak levels) were also computed for segments dominated by wind turbine rotation and uncontaminated by other noise, with typical crest factors of 13-19 dB. Totalized BPF RMS levels ranged from 56 to 70 dB re 20µPA, with peak levels from 71 to 89 dB. The RMS and peak levels are similar to those found at other sites with appeals to stop the noise, legal action, and homes abandoned.
It is understood from neighbors that they have experienced disturbance since the turbines started operating whereas prior to turbine operation there was no similar disturbance. It is understood that neighbors report improvement when turbines are shut down (not rotating) or when they remove themselves physically away from the Facility a distance of several miles.
El Paso County noise regulations define “Sound” as oscillations in pressure (or other physical parameter) at any frequency, and, prohibits noise disturbance due to acoustic oscillations.
The analysis is far from complete in that numerous segments of each day at each monitoring location could be analyzed and associated to journal entries and/or medical data. The reported association of proximity to the operating facility to disturbance in health and quality of life appears supported by the acoustic data acquired for this preliminary investigation. These preliminary investigations suggest that there is a condition of noise disturbance due to very low frequency acoustic pressure oscillations in the vicinity of the Golden West Wind Facility when it is operating, with more severe impacts downwind.
- IMMEDIATE RELEASE
STELLA- March 23, 2017
Following the Ontario Energy Minister’s statement that there is a robust supply of energy for decades to come, the Association to Protect Amherst Island (APAI) called on the Provincial Auditor-General, Bonnie Lysyk, to examine why the provincial Liberal Government is not exercising its right to terminate an expired wind turbine contract signed in February 2011 and save the Ontario taxpayers more than $500MM over the next 20 years. Windlectric, a subsidiary of Algonquin Power and Utilities Corporation, continues with plans to build a 75 MW wind project on Amherst Island that would produce unnecessary and expensive electricity costing $140 per MWh.
Although Premier Wynne admitted that the “green energy” policy is a mistake and that the electricity rates were too high, the Association’s numerous attempts to have the project terminated have been ignored. Michèle Le Lay, APAI President, questioned the Liberal Government’s logic: “Why is the Government proceeding with the industrialization and the destruction of the natural and cultural heritage of a community, allowing twenty-six, 50-storey-tall wind turbines to be built in bird and bat migratory routes, endangering at-risk species’ habitats and at the same time, risking the health and safety of the people who live there for unneeded, costly energy?”
She explained that: “Right across the channel from the Island, the Lennox and Addington Gas Plant operates at less than 3% capacity and the new Napanee Generating Station being built right beside it is slated to operate at about 30% capacity. Even worse, in early 2017, the Ministry of Energy forced the closure of Northland Power Generation Station (across from the Island) that offered to provide electricity to the grid for $59 per MWh. Something is not right about all of this”. She added : “The Liberal Government could save the Ontario taxpayers and electricity consumers between $400- and $600-million dollars over 20 years by cancelling the Windlectric contract”.
“Ontario taxpayers could use a break on their electricity bills. Why pour more money into the pockets of a large utility at taxpayers’ and electricity consumers’ expense?” said Mayo Underwood, a resident of the Island.
A formal letter has been sent to the Auditor-General of Ontario seeking a financial investigation on why the Ontario Government refuses to terminate an expired wind turbine contract and agrees to pay for the next 20 years a wind company the highest rate ever ($140 MWh estimated average rate) for unneeded electricity.

Interesting paper that challenges the conclusions published using the data collected for a study concerning sleep disturbance and wind turbine noise from a wind project located in West Lincoln, Ontario. Turbines up, documented acoustical environmental changes, sleep disturbances. Does the data support and validate the conclusions published in “The impact of psychological factors on self-reported sleep disturbance among people living in the vicinity of wind turbines,” by Leila Jalali, Mohammad-Reza Nezhad-Ahmadi, Mahmood Gohari, Philip Bigelow, & Stephen McColl, published in environmental research, volume 148, July 2016, 401–410″? Not everyone agrees.

My project is the Niagara Region Wind, which consists of 77, 3.0 MW 124m height, plus the blade length which is 101m tip to tip. These turbines exceeds the span of a Boeing 747. In my backyard. I live in Haldimand County.
It is very hard to post everything about the projects, from noise, visual pollution, a community driven apart and divided, to human health, environmental health, the corruption uncovered, the rights you no longer have and the push backs from every single level of government there is. Not one single level of government will converse with you, they have a standard response they give to everyone.
I have one IWT 680m from my home, 417m to my property line. I have one 1022m from my home, another 1322m from my home and a transfer station is 900m to my home. Within 3km’s of my home there is at least 20+ turbines.
I live remotely, dead end street with 23 beautiful acres.
It’s a very different life. There is no more quiet space. There isn’t any quiet time anywhere. They are enormous, unsightly. Visually distracting, Visually disturbing, night and day. At night I have blinking red lights that penetrate our home.
I am on a prescription for vertigo, cabin pressure and motion sickness. This is a way of life I have never dreamed of living, nor thought would ever happen. This is MY new life, not chosen by me, but rammed down my throat by the incompetent greedy corrupt liberals. Yes, the prescription helps to lessen the symptoms and at times debilitating pain, but I am on a DRUG to remain in my home most days (forced out some days).
Let me explain something. I have fibromyalgia and osteoarthritis. Both of which I do not medicate or take any scribe for. I manage with a healthy lifestyle and staying active. Now, in order to not be hospitalized for violent episodes of vertigo, balance loss and vomiting, I MUST remain on a prescription.
I can not convey my anger at this situation correctly. I can not convey to those who do not have turbines exactly what it is like to live with them. It is an experience that goes beyond ones ability to express correctly.
How do you tell people, the turbines haunt you 24/7. How do you explain to people the turbines and the IFS and LFS keep you awake all night.
I continue to battle for my rights. The same rights given to every Canadian and the same rights laid out in the constitution. But when you learn the GEA 2009 has over ridden rights, over ridden by-laws, abolished the MOECC, MNR rights and so on, you know you don’t live in Kansas anymore.
I am more than willing to discuss this on an ongoing basis.
Later I will post videos of the noise, the view from my living room and explain that as a mother how your FIGHT mode is triggered when a minor in your home is adversely affected. How you quietly retreat to your room to cry in overwhelming shame; Shame you can not provide a safe home for your family and yourself.
I truly am a different person than I was 7 months ago.
With each write to the government and agencies, I remind them I did not give up my rights, I did not consent to be a human trial project and their blatant disregard for human health will have consequences.
Lastly, I’d like to mention I have a fantastic Doctor. Most GP’s think its all in your head. My doctor understands LF’s and IFS. Due to the immense cabin pressure in my ears he acknowledges it’s time to start tracking nerve damage seeing as we are at the early stages, nerve damage which will cause hearing loss. I will be going for extensive hearing tests until further notice.
There is so much more to write….

Niagara Wind turbines came online November 2016: http://www.nrwf.ca/
Suncor wind turbines located in Adelaide Metcalfe, Ontario have generated another documented case of residents forced to abandon their home due to wind turbine noise. The letter from James and Heather Dymond reaches out to Mayor and Council demanding they find a solution. If you are also impacted it is important no matter what they say or what you are told know this- you are not alone. Please continue to speak up and send in your letters to those who are mandated to protect us.
February 15, 2016
I’m writing today to ask Adelaide Metcalfe council to find a solution to the issues surrounding Suncor wind turbines, that are causing us to have to vacate our house at night, as well as some days – since April 2015. We pay taxes to the township for a home that we can no longer enjoy. We have to leave at night to get a break from the incessant infrasound emitted from the turbines. It is a sound that one can feel more than hear.
I am suffering from nausea, vertigo, and at times extreme headaches, wherein I have to leave the house immediately to get any relief. I’ve spent countless hours in the searing sun in the summer, because I couldn’t stay in the house without feeling like vomiting. I am now on prescription meds for vertigo which I have never experienced before. The meds help somewhat, but don’t eliminate the problem. My work is livestock based on the property, and I have noticed negative effects on my livestock as well.
Suncor has been contacted, and has informed me that I am the only one with any problems and that the turbines are running within guidelines. We have not signed a contract with any wind company, yet are forced to live with the problems they create.
Since the family of Mary Ann Hendrikx has approximately six wind turbine contracts with Suncor, I have not included her on this email as it is a conflict of interest.
