A comprehensive guide to wind farm noise prediction, measurement, assessment, control and effects on people

Wind Farm Noise covers all aspects associated with the generation, measurement, propagation, regulation and adverse health effects of noise produced by large horizontal-axis wind turbines of the type used in wind farms.

The book begins with a brief history of wind turbine development and the regulation of their noise at sensitive receivers. Also included is an introductory chapter on the fundamentals of acoustics relevant to wind turbine noise so that readers are well prepared for understanding later chapters on noise measurements, noise generation mechanisms, noise propagation modelling and the assessment of the noise at surrounding residences

Key features:

  • Potential adverse health effects of wind farm noise are discussed in an objective way.
  • Means for calculating the noise at residences due to a wind farm prior to construction are covered in detail along with uncertainty estimates.
  • The effects of meteorological conditions and other influences, such as obstacles, ground cover and atmospheric absorption, on noise levels at residences are explained.
  • Quantities that should be measured as well as how to best measure them in order to properly characterise wind farm noise are discussed in detail.
  • Noise generation mechanisms and possible means for their control are discussed as well as aspects of wind farm noise that still require further research to be properly understood.

The book provides comprehensive coverage of the topic, containing both introductory and advanced level material.

The World Health Organization is currently reviewing the European Environmental Noise Guidelines:

“The guidelines will assess several environmental noise sources such as aircraft, rail, road, wind turbines and personal electronic devices. The document will also consider specific settings such as residences, hospitals, educational settings and public venues.  In addition, the guidelines will review the evidence on health benefits from noise mitigation and interventions to decrease noise levels.”

NOISE: A startling case of two schools in proximity to wind turbines

Dear Mme Héroux,

I should be grateful if you would ensure that this report reaches the ladies and gentlemen of the panel reviewing the WHO’s noise guidelines for Europe.

In an effort to assist a society in danger, I feel obligated to make this case public. I am employed in schools within a rural area. The projects I am involved in run throughout the school year. I hope it will be understood why I cannot reveal names and locations. Sadly, I must protect myself against the professional consequences which could result from a fully detailed testimony.

During the past two years, I have worked in a school located 5 km to the east of a small wind farm, whose elevation is about 300 feet above that of the establishment. Most of the time, the school is downwind from the 2 MW wind turbines. In 2014/2015, I worked with the kindergarten consisting of 20 children aged 2.5 to 5 years of age. I’ve been engaged in this work for a long time, and I know the region and its people very well.

I was surprised how hard it was to manage this class of very young children. Actually, the teacher would systematically divide the class into two groups of 10, although I usually have no problems working with whole classes. Nonetheless, I found it hard to maintain the concentration of many of these children. In addition, a lot of pupils exhibited unusual and completely improper behaviour, which was violent and disruptive. I had rarely encountered this before with children of that age group, and never in such proportions. I did not understand why at first. It wasn’t the teacher’s fault: he was kind and rigorous at the same time, which is perfect for such small children.

During the second school year, I was again assigned to that school, but this time in two classes: the kindergarten divided into two groups, and a class with children aged 6 to 7.

This second class was absolutely unmanageable during the five first sessions. Its experienced teacher commented to me it was like that most of the time, he just could not handle those children. Yet again, nothing was wrong with the teacher. Several children seemed to be extremely ill at ease, a feeling shared by the teacher. There were instances of fits, outbursts of rage, rolling on the floor, knocking tables over and provoking each other into violent behaviour. The teacher was losing confidence and was also beginning to feel ill himself, on one occasion coming very close to a burn-out. The tiredness etched upon his face reflected his struggles. It should be noted that he also had problems with his memory, and it was becoming obvious that the children’s behaviour was not the only cause of his troubles, but that the location as well was a highly plausible culprit.

I soon made the connection with the wind turbines, because this behaviour reminded me of two children I had worked with a couple of years ago: they lived 800 yards from a wind farm. Having realised that, I started to check on the wind direction every time I drove to the school, when passing the wind turbines which in any event can be seen from the village.

From the start of the 6th session the change was dramatic: this class was the most peaceful I had ever taught. The children were remarkably calm and took part in the experiments in a very constructive way, intervening advisedly, all without pushing and shoving or fighting. Notably, the wind was blowing from the east, from the village to the wind farm, not the other way around as it did previously. I informed the teacher about my observation.

Some time later, having worked during the morning in the kindergarten, I was having lunch with their teacher in the classroom before going to another school. At noon, he was called by his third colleague. The 6-7 year olds’ teacher had left the school in tears, after a horrible morning spent with his pupils who had behaved particularly violently and unbearably. While we were eating, we stopped talking for a moment. This is when I felt the school vibrating, as if a lorry were passing on the country road 300 feet away. This vibration however, did not cease. In fact, the whole school was vibrating strongly, and we listened to that humming sound for a long moment. We opened the window, but there was no noticeable source of noise outside. It wasn’t the air extraction fan either, for we could hear its less obtrusive noise separately.

The classrooms had probably been vibrating during the whole morning, but this had been covered by the background noise of our activities. There is therefore very good reason to believe that this could have been the cause of the particularly strong malaise felt in the disruptive class of 6-7 year olds during the morning. That particular room faces the wind turbines and clearly acts as a sound box. The two other classrooms are more protected, but that didn’t prevent us from hearing strong vibrations in the kindergarten room, situated at the back of the building. The teacher of that class had also heard the noise very well. It is important to note that a sustained wind had been blowing from the direction of the wind turbines for several days.

The children all live in villages situated below the wind turbines, and were born after the construction of the wind farm. I recently met the mother of one of the children. She told me about the problems caused by the highly excitable nature of her two children and their classmates. She didn’t know what to do, so she had called a woman who claimed to be able to ‘demagnetise‘ her children. She also had special EMF electricity outlets installed. When I told her about my observations, her face immediately lit up and her comment was: « it’s quite possible ! »

I had worked previously in the same school, in the same conditions and within its ancient building before the turbines were built. I retain happy memories of these times.

I have also worked, twice, in another school, located 2 km west from a similar wind farm. First it was before the wind project was built, and I had found the children to be quick-witted, with many brilliant pupils among them, one being even recognised as exceptionally gifted. The second time around, it happened 4 and 5 years after the erection of the turbines. This was a part-time job which lasted 18 months, with 8-10 year olds.

When I took that assignment, I found that a very large proportion of the pupils had special education needs, a large number of them bound to low attainment, and many had learning disabilities officially recognised (dyslexia, dyscalculia, dyspraxia etc.). Out of a class of 25 pupils, not a single one was considered brilliant. The same problems could be found in the second class, again with no children obtaining high grades. Given the high pedagogical quality of the teachers (they were the same as before the wind turbines), the eventual social problems of some of the children (not more than anywhere else) couldn’t justify the massive failure in this primary level schooling.

I thought this failure might have been caused by EMF pollution from permanent WIFI signals, and the faint natural light in the classes. But it was the same as years ago, and the same in other schools, where I had met numerous brilliant children. Again, the only difference here was the wind farm’s proximity.

Unlike the first school, and considering the prevailing westerly winds, this one was located upwind from the turbines, and at the same altitude. The children here didn’t exhibit the same violent temperaments and behaviour as those described earlier in the first case, or as the two children living 800 yards from wind turbines. On the contrary, this was a very peaceful class, almost lifeless, lacking in concentration, vitality and reactivity, with poor oral participation. A large proportion of children exhibited serious learning difficulties. In addition, when working in that school I became dizzy whenever rising from my desk, or when leaning over a child and straightening up. Here again, I thought the WI-FI was the cause (in fact it could have contributed some).

Comparing the two schools, the first one is located downwind about 300 feet below and 5 km away from wind turbines, with pupils born after these were erected, living in homes in much the same topographical situation as the school. They exhibit severe behaviour outbursts when the wind blows from the direction of the turbines.

In the second case we have a school located upwind, 2 km from another wind farm and at roughly the same elevation as its turbines, with pupils born before the construction of the wind farm, living in the same village as the school. A high proportion of them have severe learning difficulties which didn’t exist in that school before the wind turbines.

As the inquiry is about ambient noise, generally speaking, I also wish to report the harm done by air extraction fans and milking robots, which have invaded our farms. Contrary to the earlier milking machines, they don’t only work 2 x 2 hours a day, but keep humming around the clock, causing health problems to cattle and humans alike. This is not counting with the heat pumps. Actually, sources of infrasound are springing up everywhere. And although out of topic, please allow me to briefly mention the digital boards, the operation of which requires teachers to close the blinds, thus depriving a whole generation of children of natural light for a large proportion of their school day. In short, in an increasing number of schools, all these negative impacts on health add up. But clearly, from my experience as summarised above, wind turbines are responsible for the most harmful impacts.

I hope my testimony will enable you to write directives that will protect our children from these most harmful effects. I did not sign it, because too many “politically-incorrect“ whistle-blowers have lost their jobs, which is something, you will appreciate, myself and my family cannot possibly risk or afford. Only authorised persons in very senior positions know my identity. This report is, therefore, only anonymous with regard to its release into the public domain.

I should be grateful for confirmation of receipt of this letter.

The Ultimate Insult

barbara-ashbees-home
Barbara Ashbee’s home

On August 24, 2016, Barbara Ashbee from Ontario wrote to Marie-Eve Héroux, member of the panel developing the WHO Environmental Noise Guidelines for the European Region:

 

Dear Mme. Héroux,

My name is Barbara Ashbee.

I live in Mulmur, Dufferin County, Ontario and I am writing to submit information on wind turbine noise in our communities to include in your research.

An industrial wind turbine installation had serious impact on our family personally and many others in our neighbourhood, our province, country and globally.

I have met with many impacted families here in Ontario and have corresponded with others out of province. I didn’t know any of these people before the effects of wind turbines changed our lives.

In 2008/2009 my husband and I both had our health seriously impacted after a turbine project started up around our home. The adverse health effects started petty much right away.

We had loud cyclical noise and a vibration and humming in our house that made sleep impossible, ongoing, multiple nights in a row. I had no idea how serious and dangerous sleep deprivation was until I experienced it first-hand. Due to ongoing exposure to the emissions from the turbines our health declined to the point that we had to leave our home.

My husband and I were both healthy and happy adults. We took no medications and we enjoyed life and our work outside the home. We had purchased our bungalow 3 years before the turbine project was built and had done a lot of updating with plans for it to be our retirement home. We were building my husband’s new garage/workshop at the same time the turbines were being built. We had no idea that they were going to cause us problems as we had not heard of any issues from the first phase that was erected in 2006. I was taking photos and sharing them with my family as the project was erected. In fact when one of our neighbours came to us in 2006 and asked if we would have any concerns with them putting one on their property we said of course not.

We were not anti-turbine or anti-wind and we had not been informed by anyone that there were problems.

barb ashbeeWe were harmed by these wind turbines surrounding us and even as we had engineering noise reports showing out of compliance cyclical noise, a vibration and infrasound measured inside of our home and dirty electricity our government continued to tell us that the wind company was running in compliance and there was nothing they could do. Only after our pleas to our government and attempts to have the noise and vibration problems corrected did we find out that there had been many families before us that had been billeted, bought out by the developer, or forced to move because they couldn’t take living in their homes anymore.

Along with sleep deprivation we experienced headaches, stomach aches, episodes of dizziness, nausea, impaired cognitive and memory function, heart palpitations and chest pressure, infection requiring antibiotics, pressure in the head and ears, a bleeding nose that required liquid nitrogen treatment, and just before we moved out of our home my husband was diagnosed with hyper thyroidism, something he had never had before. We knew what was causing it and informed his specialist. He was not put on any medication and after we moved his levels returned to normal and he has not had an issue since.

Being exposed to the cyclical noise, the low frequency noise and infrasound left us physically ill and with no resolution offered and no ability to shut the turbines off, we were completely disempowered. Unable to have the problems fixed and unable to stay in the home we loved has been very distressing. The realization that our lives were deemed worthless by authorities was hard to take.

Our pets were also affected with one dog in particular whimpering and crying when the conditions were the worst. They were at times antsy, restless and bothered, sometimes crying, sometimes going from room to room. It was not normal behaviour. It was heartbreaking and so we started to look for a place to move. We asked locally about renting a mobile home to park on our driveway to get out of our house. We were not successful. We moved our bed into our detached garage but the noise and vibration was no better. We started to make inquiries about renting another house but with three dogs and 2 cats it was not easy and it is extremely hard to leave everything we had knowing that if they would just shut the project off we could at least get some sleep. We kept hoping a solution was around the corner. We just kept trying to resolve it.

An attempt by the wind company was made to move us to a property that they had purchased one concession over from us but it was rank with mold so we had to abort that. In the end we purchased a tent and we moved our bed, a night table, a lamp and a heater out into the tent and spent our remaining days on our property sleeping outside. The vibration was not as bad as it was in the house and they had agreed to shut 5 surrounding turbines down. While it was pretty cold some nights, it was better than in our house. Our pets slept outside with us.

I am quite confident you will hear the word torturous from other impacted people and I can attest to the fact that description nails it. To be deprived of sleep, with no power to shut the noise or vibration off, to have your health decline from the impacts of the noise, infrasound and vibration in the sanctity of your own home, the very place you normally turn for restorative sleep and relaxation is pure torture. It is unbearable. It is spirit crushing and heartbreaking.

The ultimate insult of having gone through this, to having fought for our home and lost, to losing faith and trust in any authority that we thought was concerned about people’s health and wellness, is to have it happen to even more families in our area and globally because it continues.

Were you to meet any of these families, the small children, the seniors, teens, it doesn’t matter age, gender, race, religion or economic background, if you could meet with these people and listen to them, it would be a huge step in understanding. Please, as you consider the research, the academic input, the physicians, acousticians and others who are giving you information, please also talk to the people. Talk to the ones who have been harmed. Talk with the families who have first-hand experience. You will find their personal accounts and symptoms are the same regardless of what country they come from or what language they speak.

I am appealing to you to investigate fully and to order turbines cease operation until the people have had a genuine hearing of their complaints. Nobody consented to having their lives so negatively impacted. This is clearly a case of terribly flawed policy trumping health and wellness.

It should never have happened.

– Attached is a compilation of statements from wind turbine affected families in Ontario that were drawn from early news reports, personal comments from meetings and testimony from different communities in Ontario. This compilation is a number of years old now and represents a small snapshot of affected families. The purpose for compiling it was to inform our government that the complaints are the same and that they are growing. Hundreds more turbines have been built since and every project has additional impacted families. Not only did early turbine projects cause harm but the newer turbines are much larger and yet the setbacks remain the same.

In the past 8 years since this happened to us, I could supply reams of letters, documents and testimony all supporting the need for an investigation and for the turbine projects to cease operating so innocent families can live in their own homes and try to recuperate from the turbine emissions that harm them.

The people living among these wind power centers need relief.

That these projects are allowed to continue to operate where complaints, illness and home abandonment have been made is cruel and inhumane.

Please keep me posted on your progress with your research and please contact me if I can help in any way. I am pleading with great urgency that you please help those who are being impacted right now.

With respect,

Barbara Ashbee

Environmental Noise & Sleep

Environmental noise and sleep disturbances: A threat to health?

sleep

Environmental noise, especially that caused by transportation means, is viewed as a significant cause of sleep disturbances. Poor sleep causes endocrine and metabolic measurable perturbations and is associated with a number of cardiometabolic, psychiatric and social negative outcomes both in adults and children. Nocturnal environmental noise also provokes measurable biological changes in the form of a stress response, and clearly affects sleep architecture, as well as subjective sleep quality. These sleep perturbations are similar in their nature to those observed in endogenous sleep disorders. Apart from these measurable effects and the subjective feeling of disturbed sleep, people who struggle with nocturnal environmental noise often also suffer the next day from daytime sleepiness and tiredness, annoyance, mood changes as well as decreased well-being and cognitive performance. But there is also emerging evidence that these short-term effects of environmental noise, particularly when the exposure is nocturnal, may be followed by long-term adverse cardiometabolic outcomes. Nocturnal environmental noise may be the most worrying form of noise pollution in terms of its health consequences because of its synergistic direct and indirect (through sleep disturbances acting as a mediator) influence on biological systems. Duration and quality of sleep should thus be regarded as risk factors or markers significantly influenced by the environment and possibly amenable to modification through both education and counseling as well as through measures of public health. One of the means that should be proposed is avoidance at all costs of sleep disruptions caused by environmental noise. house and wind turbine

Negative health impact of noise from industrial wind turbines: How the ear and brain process infrasound

Author:  Punch, Jerry; and “James, Richard”>James, Richard

This article, the final of three installments, discusses the relationship between various health effects and our current understanding of the processing of infrasound by the ear and brain. [Part 1: Some Background; Part 2: The Evidence.]

As noted in the second installment of this series, Dr. Geoff Leventhall, a co-author of the 2009 AWEA/CanWEA report, attributes the health complaints of people who live near industrial wind turbines (IWTs) to psychological stress, but does not acknowledge that IWTs can be detrimental to health because infrasound and low-frequency noise (ILFN) emitted by wind turbines are largely inaudible to humans. He stands on the argument, therefore, that what we can’t hear can’t hurt us.

We know that things we cannot see, touch, taste, or smell can hurtus, so why is it unreasonable also to believe that what we can’t hear might also hurt us?

Dr. Nina Pierpont, in describing Wind Turbine Syndrome (WTS), has expressed her belief that many of the symptoms comprising WTS are mediated by overstimulation of the vestibular system of the inner ear by ILFN. Recent evidence supports the general view that the functioning of both the vestibular and cochlear components of the inner ear, and their interconnections with the brain, mediate the type of symptoms that Pierpont and others have described.

INFRASOUND: MORE OF A PROBLEM THAN WE THOUGHT?

Industrial-scale wind turbines generate peak sound pressure levels at infrasonic frequencies, especially between 0.25 and 3 Hz, as the blades pass in front of the tower. Most of us do not experience the energy in this lowest of low-frequency regions as sound; instead, we perceive a variety of other sensations. When present, infrasound can be more of a problem than audible sound.

Recent basic research on the inner ear conducted by Dr. Alec Salt and colleagues at the Washington University School of Medicine in St. Louis has provided a feasible and coherent explanation of how sound that is normally not audible can result in the kinds of negative reactions reported by people who are exposed to wind turbine noise. That research has shown that extremely low-frequency sound is largely inaudible to humans because the outer hair cells (OHCs) in the inner ear detect and effectively cancel it before it reaches the inner hair cells (IHCs). The IHC stereocilia, which do not contact the tectorial membrane, are fluid-coupled and sensitive to stimulus velocity, while the OHC stereocilia are sensitive to displacement. IHCs rapidly become less sensitive as stimulus frequency is lowered.

Readers familiar with the anatomy of the ear know that approximately 95% of the fibers innervating the IHCs lead to the brain as afferent fibers, while only about 5% of the fibers innervating the OHCs are afferent fibers. Thus, we hear through our IHCs, and our hearing sensitivity is comparable to the calculated IHC sensitivity. The OHCs, which respond physiologically to infrasound, serve as a pathway for infrasound to reach the brain. Infrasonic signals that reach the brain are normally not perceived as sound, but are believed to stimulate centers other than auditory centers, resulting in perceptions that may be unfamiliar and disturbing.

Similar pathways to various centers of the brain also exist through the vestibular, or balance, mechanisms of the inner ear, meaning that it is biologically plausible for infrasound to produce the variety of sensations described by Pierpont, sensations such as pulsation, annoyance, stress, panic, ear pressure or fullness, unsteadiness, vertigo, nausea, tinnitus, general discomfort, memory loss, and disturbed sleep.

Salt and colleagues have also found that when higher-pitched sounds (150-1500 Hz) are present, they can suppress infrasound. This means that the ear is most sensitive to infrasound when higher-frequency sounds are absent. This occurs at night when wind turbine noise is present, ambient sound levels are low, and higher-pitched sounds are attenuated by walls and other physical structures.

As utility-scale wind turbines increase in size and power, the blade-pass frequency goes increasingly deeper into the nauseogenic zone.
As utility-scale wind turbines increase in size and power, the blade-pass frequency goes increasingly deeper into the nauseogenic zone.

Another relatively recent discovery is that there is likely a cause-effect relationship between AHEs and ILFN that mirrors that occurring in motion sickness. An experiment in the late 1980s, conducted using training-mission scenarios with Navy pilots, showed that motion sickness was associated with significant amounts of acoustic energy inside the flight cabin over the frequency range from just under 1 Hz to as low as 0.05 Hz (the nauseogenic range). Maximum sensitivity occurred at approximately 0.2 Hz. That experiment resulted in the conclusion that flight simulator sickness may be, to a significant extent, a function of exposure to infrasonic frequencies. This phenomenon is akin to seasickness, except that the acoustic energy causes nausea without body movement or visual stimulation.
wind noise

Dr. Paul Schomer, nationally and internationally known for his work in acoustics and acoustic-standards development, has suggested that because the Navy test subjects responded to acoustical/vibratory energy with symptoms similar to motion sickness, many of the similar symptoms reported by people living near IWTs can be explained by exposure to infrasound from wind turbines at frequencies similar to those observed in the Navy’s test environment. Persons affected by wind turbine noise appear to be responding directly to acoustic stimulation of the same nerves and organs affected in that experimental environment.

DATA SUPPORT REPORTED SYMPTOMS AS BIOLOGICALLY PLAUSIBLE

These research efforts of Salt and colleagues, Schomer, and others are leading the way in establishing the biological plausibility of the harmful effects of ILFN generated by wind turbines.

Dr. Salt dismisses the common perception that what we can’t hear can’t hurt us and has stated unequivocally that “Wind turbines can be hazardous to human health.”

Decisions regarding the siting of industrial wind turbines deserve careful attention to limiting noise exposure levels in community residents through specified restrictions on either distance or noise levels, or both. The right of the public to enjoy health and well-being should be paramount to the economic and political interests of the wind industry and governmental bodies. These rights need to be protected on a proactive, and not just on a retroactive, basis. Industrial-scale wind turbines should be sited only at distances from residents that are sufficient to minimize sleep disturbance and that do not put them at risk for a variety of other serious health problems.
