Health Effects of Industrial Wind: The Debate Intensifies (update with Steven Cooper)

By Sherri Lange -- July 30, 2020

“Exposing the fact that the cost-benefit analyses for wind farms are wrong, the power output modelling is wrong, the acoustic modelling is wrong, and the acoustic dose response data is wrong could create some interesting discussion on the back of Planet of the Humans.” (Steven Cooper Interview, June 2020)

Master Resource has followed the work of acoustician Steven Cooper for some time. In a February 2018 interview, Sensing but not Hearing, Mr. Cooper explained how all-body hearing mattered more than acoustic isolation and reporting.

“On discussing the residents’ observations (with the residents) for the first two weeks,” he stated, “I found the use of describing the impacts in terms of Noise, Vibration, and Sensation was accepted by the residents as a better concept.”

In a November 2019 update, (Two parts, Sensing but not Hearing, Latest), Mr. Cooper asked: “I question how an authority can propose noise criteria with no fundamental basis identified as to how a stated core objective can be satisfied.”

Today, we speak again with Steven Cooper about new research explaining why acoustic measures by wind developers are not supported with any meaningful measures or predictions from models. This interview builds upon and updates the previous two in regard to his published and presented ground-breaking work.


Question: Can you update us on your conferences, research, and presentations?

Cooper: My original concept was to determine and reproduce an accurate sound signal of wind turbine noise to then permit multi-disciplinary investigation of what the noise was doing to people and what parts of the body were reacting to the noise.

That concept has ventured into multiple investigations over the years that have been progressively presented to the wind turbine working group of the Acoustical Society of America, and then by invitation has extended into Europe.

My work has questioned/examined what our general acoustic analysis provides and the errors in such analysis; threshold of hearing and threshold of sensation; the challenges in creating that sound; subjective assessment of mono vs. stereo; and the infrasound sound of wind turbines versus the pulsation of  the wind turbine sound that is occurring at an infrasound rate.

I have also done a case study that showed sensitive people can identify the presence of an inaudible wind turbine noise,  putting the Kelley Mod-1 work (in the 1908s) with the work on fluctuation from Zwicker and Fastl, clarifying the incorrect use of Amplitude Modulation in relation to wind turbine noise, and with the assistance of a psychologist in a single case study, showing the response of the inaudible pulsating wind turbine noise was centered in the frontal lobes of the brain.

As a result of the International Congress of Acoustics (ICA) and the European Acoustics Association (EAA) TC Noise meetings in Germany last year, there was a request for a special Edition in Acoustics on Wind Turbine Noise. Recently a Technical Note (by Cooper and Chan) on acoustic compliance of wind farms was peer reviewed and published in Acoustics

Having entered the fascinating world of psychoacoustics I have been able to re-analyse the Cape Bridgwater data in terms of the power output hypothesis and the modulation index and have found an amazing correlation with the complaints/observations. I propose to submit two more Technical Notes to be published in the Special Edition in Acoustics if I can make the deadline. 

Question: What was the response of your colleagues to your materials presented?

Cooper: So far, I have received a great deal of encouragement to continue the work. In Germany last year at the ICA conference I had a number of senior acousticians (who collectively have published a significant number of papers on wind turbine noise) seek private discussions so they could discuss in detail the three papers that I presented (a lot of material packed into a short presentation).

In other presentations there were acknowledgments that the presenter had used the wrong terminology in the relation to wind turbine amplitude modulation (when it should be modulation of the amplitude). Those public acknowledgments to other acousticians indicate a shift in the acoustic terminology for wind turbine pulsations.

The recognition of my work in Europe, appointment to the EAA technical committee on Noise and a request (to my wife) by a number of esteemed professors to continue my research and not retire was astounding. In relation to the recent Technical Note published in Acoustics I received an email from Dr Paul Schomer congratulating me on the paper and my identification of issues with the noise dose response/setting wind turbine limits.

To receive that email from Paul I consider to be the highest honour I could obtain in acoustics.  

Question: You have indicated in your notes to us that the WHO (World Health Organization) has incorrectly set 2018 criteria for wind turbines, despite being critical of the limited number of noise studies. Can you explain this?

Cooper: In many socio-acoustic studies the input of acousticians is a small component and does not involve validation of predicted levels versus real levels. If the researchers didn’t understand that the wind turbines do not operate at full rated power all the time, and they weren’t acousticians who would be aware of that very fact (whereas THE COMMUNITY IS AWARE THE WIND IS NOT CONSTANT AND NEITHER IS THE NOISE), then it follows (as night follows day) that what turbine noise the residents had been exposed to for some time would be lower than the predicted levels.

Therefore, the noise scale on the dose response curve should be shifted to the right. This shift leads to a lower noise level for the general limit derived for 10% of the community highly annoyed.   

Going to the wind turbine noise curves in the WHO 2018 Guidelines they are not all using the same acoustic parameter. In the recent Technical Note, we corrected the curves on the assumption of the same noise all the time. When that data is reviewed then, using the normal 10% highly affected level, the WHO recommended limit is too high.    

Health Canada relied upon predicted noise levels for their analysis – again no validation exercise to identify the actual noise versus the predicted levels. The study report does not identify any exercise to ascertain how the turbine noise/power of the turbines would have varied over the period prior to and during the survey.

The Health Canada study did not know the actual wind turbine noise during the survey or how it varied during the survey. But they provided a dose response curve. Now if the two wind farms were subject to only an average power output of say 30% then it follows that the average noise would be significantly lower than the predicted levels. Therefore, in reality the Health Canada recommended noise levels for wind turbine noise that should have been lower.

Question: So, you are saying that the noise criteria to protect the community from adverse impacts from WHO references, Guidelines, and Health Canada’s recommendations, are not correct?

Cooper: Yes. Neither the WHO nor Health Canada identified actual wind turbine noise levels to protect the community from adverse impacts – because they used predicted levels without any validation of what the actual noise levels were (when compared to the predicted levels).

On a purely statistical basis the number of complaints in relation to wind turbines says there is something wrong with the suggested criteria. Environmental Authorities and wind farm operators conduct compliance testing and say it meets the relevant guideline or permit condition.

But the residents are still affected, complain of sleep disturbance and adverse impacts. So therefore, for the “complying wind farm” there presents a conflict with what the guidelines say will not create adverse impacts or sleep disturbance and reality.

Part of the problem is that various people on the various independent expert committees, the bulk of them, are not acousticians, or people who would have any understanding of the how (and when) wind farms operate.

Not like the work of Dr Kelley on the MOD-1 turbine where the report clearly stated that some of the residents were disturbed (when the predictions said that would not occur). More importantly the report of Dr Kelley and his team identifies the complaints were confirmed and not imagined.

The important thing to comprehend is that for the UK and Australian criteria they are based upon the WHO Community Noise 1995 document that provided a limit to protect against sleep disturbance. But the sleep disturbance criterion was based on traffic noise not wind turbine noise.  So, the concept of achieving wind industry noise limits that “will automatically ensure there are no sleep or health or noise impacts,” is clearly based on a false premise.

The WHO 2018 Guideline clearly stated there was insufficient data to provide any advice as to sleep disturbance noise limit. Why?  Because there are no studies on actual wind turbine noise AND the six questions I posed in our previous interview have still not been answered.

Question: On examination of the WHO Guidelines, 2018, as discussed above, it seems obvious that the “conditional” recommendation (page 97) that policy makers reduce noise from turbines to below 45dB L den, is useless and invalid.  So we can safely say all development of wind without adequate noise protections is a house of cards. Facile, unregulated, and improperly guided by any meaningful principles around noise measurement, impacts of impulsive sound.

Cooper:  In the 1990s, the UK developed criteria for wind turbine installations (ETSU-R-97). The document identifies the limits are to protect against sleep disturbance, but they used road traffic noise as the basis of the sleep criteria.

So, if the Authorities used traffic noise sleep disturbance criteria for wind turbine noise then from the start there is a major problem.

ETSU-R-97 identified the operation of wind farms with a maximum of 450kW. But the document did not identify what the actual noise was from the turbines.

That means that where there were no complaints the wind turbine noise level could not be measurable or significantly below the background level or the nominated sleep criteria. No material in ETSU-R-97 (UK Working Group publication regarding Assessment and Rating of Noise Related to Wind Farms)  to explain the sleep criteria versus the actual wind turbine noise levels.

It would have been appropriate to call the criteria preliminary or precautionary or subject to further revisions.

But we have in New Zealand and Australia wind farm noise limits based on ETSU-R-97 and applied to turbines somewhat larger target as than 450kW (being the largest turbine identified in ETSU-R-97).

But the basis of the noise limits in New Zealand and Australia are not supported by any wind farm dose response curves for the size of modern-day wind turbines or any studies into sleep disturbance as a result of modern-day wind farms.

But to be fair to the WHO they provided their criteria with a qualification of limited dose response data, no reliable sleep data and indicating a precautionary approach.

If you follow the above material, then the criteria may not be useless in that it is lower than some of the criteria used around the world.

On the basis of the WHO suggested limits it is appropriate for Environmental and Planning Authorities to undertake due diligence in reviewing their criteria/policies.  A guideline from the WHO is not a regulation or a policy directive that becomes conditions of consent on a permit.

Courts can be presented hundreds of residents who provide evidence of being impacted by wind turbine noise. But the judge can say that he/she is bound to consider the application with respect to the policy/guideline of the state authority responsible for noise – not the complaints or evidence of disturbance.

In response to your question you need to understand that the precautionary wind turbine criteria issued by the WHO in 2018 relies upon predicted wind turbine noise levels. There is no material in the four social surveys referred to in the WHO Guidelines (in relation to wind turbine studies) that validated the actual noise levels versus the predicted wind turbine levels.

Furthermore, the assumed wind turbine noise levels (used by WHO) were not validated to exclude the wind noise or the vegetation noise. These additional noise components as a result of the presence of wind need to be addressed in deriving a noise contribution.

Hence my recent Technical Note raises points for consideration if such due diligence reviews were to be undertaken.

In light of the number of complaints around the world in relation to wind turbine noise, one must not follow the path previously used of just undertaking literature reviews of what other authorities have done (e.g. ETSU-R-97) —without actually analysing that material and determining its relevance to wind turbine noise.

Reviewing the development of various acoustic Standards used around the world will find (when going back to the original sources) a number of assumptions or empirical concepts used to formulate such procedures/assessment methodologies.

I found such examples in room acoustics (for echoes in rooms) in my Master’s research and identifying an error in the FAA’s INM program regarding lateral attenuation for aircraft noise (acknowledged by the US Aircraft Standards committee in 2003) as part of a PhD research study. It is this sort of questioning (raised by my supervisor) that has caused me to question the basis of the wind turbine noise criteria and the number of complaints that question the criteria.

The above situation has occurred in Australia, Authorities saying the criteria is to protect against sleep disturbance as a result of wind turbines, when there is no such data to support that position.

Question:   So what you are saying is that if the authorities were to undertake a due diligence review of their wind farm noise policies in light of the WHO identifying very limited data to provide anything but a precautionary approach, then there are important technical issues to resolve in the acoustic compliance process.

Cooper: Yes, there are a number of technical issues to be sorted out in deriving the actual noise emission for a wind farm to truly present the noise contribution for comparison with the appropriate criteria. It is those matters that I raised in the recent Technical Note.

I raised a number of matters in relation to separating the ambient noise from the overall noise that was measured. But more importantly I think Case Study D presents issues as to misrepresentation of the actual operating conditions and an assumed power output of a wind farm that becomes critical in any claims of acoustic compliance with permit conditions.

For example, Case study D in the Technical Note expands the issue by questioning the material to establish that the various wind farms used in the four dose response studies referenced in the WHO 2018 guideline. On going to the various papers for the four studies there is no identification of the actual power output versus the dose responses based upon predicted levels for maximum power.

Question:   So if the wind farms were operating at a lower power output and therefore gave rise to lower noise levels, then the community reaction determined in those social surveys would be incorrect because the responses would be occurring for a lower noise level that suggested in the prediction method.

Cooper: Correct. You now have the concept that the basis of noise criteria for wind farms may not be correct by using predicted noise levels.

But case study D goes a step further because it highlights the fact that the wind across a wind farm is less than the predicted wind because of the interference in flow of wind by reason of the number of the turbines being present (and the layout of the wind farm). Upwind turbines result in disturbed air for turbines downwind. The presence of wake reduces the ability of the wind farm to obtain the predicted power outputs AND the effect of wake vortices extend outside the wind farm and can give rise to increases in noise and annoyance.

Question:  Does this mean in terms of noise modelling one cannot consider each turbine as operating on its own?

Cooper: Yes. There is a fair bit of theoretical material on separation/spacing distances between turbines that show significant reductions in wind speed (and directions) across a wind farm when compared to the assumptions for the pre-wind farm situation.

Question:  You then add in the use of meteorology masts outside the wind farm to provide a hub height wind speed that does not represent the average wind across the wind farm.

Cooper: Yes. But in the real world you can only show that material when you have access to the SCADA material for the subject wind farm that provides all the operating parameters for each turbine.

Question:  In case study D you show for Cape Bridgewater how the angles of the turbines vary across the wind farm, and you reference other figures in the Cape Bridgewater study to show that point. But you then identify the use of wake-free wind data in compliance testing (using the regression line method) misrepresents the true acoustic compliance results.

Cooper: Yes. By using wind data for a wake free situation (by meteorology masts outside the wind farm) the wind will be higher than across the wind farm. This shifts the regression line data to the right and makes compliance easier. But the compliance report fails to identify the inaccuracy of the regression line re the wake free wind data versus the actual wind on the wind farm.

But more importantly the shifted data is not quantified in terms of the power output of the wind farm. The compliance test uses synchronised wind and noise data that is averaged over a period of time. There is no identification of the wind direction nor identification of the averaged power output.

If the wind farm during testing is only operating at say 25% of the rated power output then how can that compliance test be compared with the permit limits – particularly as there is no stated qualification (in the compliance report) as to the operation of the wind farm during the testing.

 Question: The question of incompetence or gross negligence arises.

Cooper: There is a severe level of incompetence on the part of Environmental Agencies responsible for protecting the community from harm. Their “acoustic experts” did not do the correct due diligence in relation to wind turbine noise.

So, you get the few really independent acousticians around the world (who have worked at the “coal face”) when confronting the response from the community in relation to wind farms say, hold on a second, there is something not right.

I don’t mean to isolate out some acousticians here, but to some extent it is noticeable and inevitable that I would be able to “Test Drive” some of the work and study being done internationally.

Some of the best, Rand, James, Ambrose, Swinbanks (US), Stigwood (UK), Metalka (Canada), Thorne (NZ), Cooper, Huson, Hansen and Hansen (AUS) have continued to work on the problem for years (except for Hansen and Hansen, all are unfunded), to slowly try and get to the bottom of the mess – but this group is getting on in years, and the younger acousticians (without the experience of solving problems) go with the money and do not question if the industry “facts” are correct.

Sometimes, quietly following a presentation, an interested professional or acoustician will approach me and ask for clarification on amplitude modulation or limitations on digital frequency analysis and so on. So that coaching continues for me as an integral part of my work.

Question: You mentioned that disturbed air flow or “dirty” air downstream is often ignored and contaminates the real discussion and real facts. Can you explain?

Cooper:Yes. This is a very important fact:  Using wake-free wind data for compliance testing is SIMPLY incorrect.

The issue of dirty air downwind of turbines and disturbed inflow air has been around for a while, but the material in the Technical Note in Acoustics from an electrical viewpoint has sent me off in a new direction. Enhancement of the noise due to wake vortex kilometers downstream of the turbine just opened up a whole pile of boxes that fit in with one of the concepts I proposed from the Cape Bridgewater Study.

Putting the wake free noise curve data with the power losses then led me to assess the actual power output when wind farm operators undertook the compliance testing –  it is so low that the compliance test needs to have a qualification  (for example) “ these results relate to the average power output of the wind farm at 23% of the rated power.” 

Such a statement automatically says, “hold on, how does that data demonstrate acoustic compliance – surely at high wind from power output levels, then the noise must be greater.”  Are such “wind farm compliance tests” misleading the Environmental Authorities overseeing compliance with permits? Or if the Environmental Agency undertakes “compliance testing” are they misleading the community?

But another question then arises from the above: “If we use the actual average wind speed across the wind farm, the results shift to the left and reveal high noise levels for the actual wind the wind farm experiences”.

Question:  Well that puts the cat amongst the pigeons. Let me see if I have this right:

· The testing results may include wind noise and wind vegetation noise.

· So, this means the actual wind turbine noise could be lower.

· The wind turbine dose response curves contained in the WHO 2018 guideline were predicted noise levels – not actual noise levels at the residential receivers.

· The wind turbine dose response curves in the WHO 2018 guidelines did not involve a validation exercise to ascertain what noise was being generated at the time of the survey or for the period before the survey.

· If the predicted levels used in the dose-response studies were for the maximum output of a wind farm then it is possible that the community responses have been placed in the wrong noise level category.

· Due to the presence of turbines on a wind farm the wind at individual turbines can be lower than outside the wind farms. This means that it may not be possible for a wind farm to obtain its rated capacity.

· The wake from upstream turbines can affect the operation of a turbine and cause disturbed air, reduce the output of the downstream turbines and because of the disturbed air gives rise to greater noise level and/or increased modulation.

· The use of graphical results to show the difference between the wind farm operating versus off does not identify the operating parameters of the wind farm.

Cooper:  Yes, that is a pretty good summary. We already know from the wind turbine dose response curves in the WHO Guidelines that people are more sensitive to wind turbines than for road traffic noise. And if the assumed wind turbine dose response curves are based upon predicted levels that are too high then the assessment criteria are wrong.

This has relevance when you consider the vast amount of money on the Canadian Wind Farm Health Study (Health Canada Wind Turbine Noise and Health Study) used predicted levels and failed to validate the operations of the wind farms (and the resultant noise) with respect to the predicted levels.  

Furthermore if we don’t know the actual wind turbine noise levels that people experience from wind farms that gives rise to sleep disturbance then how does one undertake sleep studies to determine the wind turbine noise contribution that will not give rise to sleep disturbance? 

Lange:  Thank you so much Steven, for the clarity and perspective. What continues to astonish many of us, is that massive outlays of turbines continue to be developed, with no standard acoustic or physical safe “setback,” and as you note, built on false premises and faulty predictions. This is a broken clock that does not even tell the correct time twice a day. It reminds us of the Waubra Foundation’s Definitive Document on your work. And, we must again wonder, does your work bring out calls for legal correction. Rhetorical.

Appendix: Waudra Foundation on Cooper’s Work

“Since measurements and predictive noise models for wind turbines being expressed in dBA exclude accurate measurement of infrasound and low frequency noise, it follows that dBA is useless as a proxy for predicting damage to neighbours, or for setting Standards to protect them from harm. Even before Steven Cooper’s investigation, the wind turbine noise Standards were known to be dangerously inadequate.

Responsible authorities should have altered the Standards to include sound as a whole and infrasound in particular, especially after Dr Neil Kelley’s work establishing direct causation from infrasound and low frequency noise resurfaced in mid 2013. Steven Cooper’s work at Cape Bridgewater (our note: and his subsequent diligence and reporting on irregularities, bad data, non sensical standards of all kinds,) reinforces the need for urgent revision of existing Australian (and OTHER) standards and regulations, and to develop a standard for “sensation”.

These current Standards are now known to be dangerous, clearly do not protect people, and must not ever be used again.

Dr Laurie continues on the value of the Cooper studies:

If this Cape Bridgewater research, commissioned by a wind developer, conducted by an ethical independent acoustician with the cooperation of both the wind developer and the affected residents, is not acted upon immediately to prevent further harm, the public authorities and politicians who choose not to act are then in a position of knowingly allowing the serious damage to physical and mental health from impulsive infrasound and low frequency noise from wind turbines to continue.

Given that the most serious and common complaint around the world from neighbours to industrial wind turbines and other sources of impulsive infrasound and low frequency noise is repeatedly disturbed and interrupted sleep, (resulting in prolonged and chronic sleep deprivation, which itself is acknowledged as a method of torture by the UN Committee against Torture xxviii), the individual public officials are risking future charges against them….

Immediate action is required from public officials at every level of government who are responsible for the current situation. This is not only to prevent further serious damage to human health, but also to reduce officials’ personal risk of future successful prosecution against them by severely impacted rural residents, for torture or acquiescence to torture, or for ignoring ongoing cruel, inhuman and degrading treatment, about which officials have been repeatedly personally advised.

    Thanks to Sherri Lange and Steven Cooper for this complex and in depth exploration of the acoustic affects of low frequency noise and infrasound produced by industrial wind turbines. It is obvious that the accurate reporting of this problem has been disregarded, and resulted in both human and animal harm worldwide. Admittedly, I have read this interview twice, and feel the need to review it yet again to truly understand it all! It is well worth the effort.


  3. Sherri Lange  

    Suzanne, Albright, thank you. It is indeed complex, and worth reading a few times! Steven Cooper again has raised the bar for putting truth on the table about impacts, and predicting, and modelling, and reporting. ILFN, and pressure pulsation, and however you wish to term it, are traditionally denied by the industry. Harder to do this by the minute. Imagine the complexity of these monster size machines, bigger by the day, in and of themselves, grinding machines, with over 8000 parts, some tested, some not, and then add air pressure, temperatures, MULTIPLE machines competing for wind, topography, and try to “normalize” that into predictive “safe areas,” setbacks, for residents. Just famously ridiculous as a thought.

    Getting compliance on ILFN (loosely termed), will be an uphill battle, but one that not a few are fearful of. Be wary of this, because it is coming, Mr. Wind Developer. As Zoning Boards become more savvy, this will certainly be part of the conversation, not merely dBA. In Ontario, Canada, where there are about 3700 or so wind turbines, compliance over mere audible noise is a huge issue, and the PC government will soon have to deal with this. KNOWN to be out of audible compliance, and KNOWN ongoing suffering, despite the shut down basically of the industry for the very long foreseeable future. Premier Doug Ford calls wind, a “scam.”

    I think Mr. Cooper has said it so well: “Furthermore if we don’t know the actual wind turbine noise levels that people experience from wind farms that gives rise to sleep disturbance then how does one undertake sleep studies to determine the wind turbine noise contribution that will not give rise to sleep disturbance?”

    Thanks for commenting.


  4. Jon Boone  

    Good, literate discussion of one of the noisome issues with this malign, goofball technology. The audible (within the normal hearing range) sound this technology makes when it is operating is easy to document, as many have; I was one of the first to do so when, in a regulatory hearing, the wind developer claimed his turbines would sound just like a breeze rustling the leaves. That the guy’s pants were on fire after everyone heard my video was a wonderful moment in my life.

    The harder to document and in some ways greater problem is wind infrasound, for this is what people living under a windplant complain about most. It transforms the issue from being an awful nuisance to a significant public health problem. Neil Kelley’s recent work on this is therefore extremely helpful. Eventually, it will find its way into both the courtroom and regulatory hearings. Finding juris prudent enough to understand it and hold the industry accountable is/will be, another matter. Few things are as broken these days as the American system of law and justice.

    A final comment: please lose the Orwellian sobriquet “windfarm.” The only term more grating about this creepshow is “windpower,” another oxymoron–since wind cannot provide modern power, only desultory energy.


  5. Sherri Lange  

    Comment from Dr. Ben Johnson, IOWA, a contributor to Master Resource, via email to Lange. As follows:

    Quote, abridged

    Rick James sent me your 7/30/20 interview with the comments on the last page by Dr. Laurie last night.

    You just can’t assume that all the complex variables that are relevant to an outcome are “normalized” and subsequently then are used to correct the outcome.

    AS I have been constructing compliance language for audible sound, I kept wondering how to calibrate (and verify) that the IWTs were operating at stated maximal Sound Power Levels AND wondered if the “linear array and clumping” IWT siting actually produced effectively lower (or higher) levels of noise then would be expected based on rated Sound Power Levels that use predicted (not measured) noise levels as assumed with single turbine operation, in steady winds without “conflicting and additional noise sources”. There are ASSUMPTIONS about adding 3 to 7 dBA for additional IWTs “squeezed into an easement”.

    Further, if a reasonably good day of “stronger than average winds” was used to generator receptor location dBA data – would that be the maximal potential exposure?

    Through Rick James’ help, we have requested (yet to be approved) Wind Ordinance language that SCADA data should be available in a 24 hour period around the time of any noise complaint. Given Cooper’s comment, does the SCADA data then calculate the % of maximum exposure possible which is a exponential relationship – not linear – indeed I doubt such SCADA data would allow theoretical IWT potential performance let alone the performance of nearby IWTs in determining implications of possible sound levels (audible or ILFN) for a given complaint or even possible “worst case scenarios” which I believe should be the ultimate target of compliance enforcement.

    What do you think is the best ILFN language that defines setbacks and measured noise levels …. to protect residents. What does Cooper think?

    End of Quote

    Thanks, Dr Johnson, for these questions! Passing them directly to Steven Cooper.


  6. Sherri Lange  

    Jon Boone, thank you as ever for your cogent comments, and reclaiming of sanity in this fight against a “goofball technology,” and reaffirming that “farm” is not a word we could usefully employ in any discussion of this scam.

    Leaves rustling in the breeze, substations that are the size of a refrigerator, noise that is like crickets, or a bowl of Cheerios with milk, these are some of the ridiculous statements offered by wind developers to often unsuspecting communities, until the realities of the build out. Then, when turbines have invaded, the language changes: like an airplane overhead that never flies away, like the most annoying thunder, low pitched, the lights like tormenting visions of an apocalypse; actual words from victims. This descriptive list is lengthy and alarming.

    And then, add the ILFN. Not heard with the human ear, but felt, in organs and the entire body, as mentioned in a previous Master Resource piece with Cooper. As you point out, Mr. Boone, that is the ultimate harm: that is the disease producing, ongoing bombardment to the entire human system of life, depriving of nourishing sleep. We are needless to say, ever grateful for your testimonies, and your writings about the oxymoron of wind. Thank you!

    Here is a quote from yourself in Master Resource that perhaps some will enjoy reading again:

    “Windspeak: Language used by those who profit financially, politically, or ideologically from wind technology that disguises, distorts, or reverses the meanings of words in order to promote the technology. Oxymorons, which combine incongruous or contradictory terms, abound in windspeak—viz, windpower, wind capacity, responsible windpower (double oxymoron), windfarms, windparks, wind jobs, wind reliability workshops, and wind as alternate energy. Generally any claim made for the technology in windspeak produces the virtually opposite effect in reality.”



  7. Michael Spencley  

    A very interesting update by Steven Cooper on where we stand in this wind turbine debacle from a lack of appropriate standards legislative point of view. In quoting Mr. Cooper; “There is a severe level of incompetence on the part of Environmental Agencies responsible for protecting the community from harm. Their “acoustic experts” did not do the correct due diligence in relation to wind turbine noise.” Both the WHO 2018 Guideline and the Health Canada Wind Turbine Noise and Health Study are being used by developers worldwide to satisfy meaningless compliance standards.

    The US government needs to reappropriate a portion of the funds held back from the WHO to fund a definitive international study led by Steven Cooper to measure and correlate all of the outputs from wind turbines and their document their direct and indirect negative health impacts on humans and animals so that appropriate safety regulations can be enacted. Accordingly, further funds should be set aside to buy-out and remove the contracts for the wind turbines causing harm.

    Many thanks to Sherri Lange and Steven Cooper for this excellent article, and to Master Resource for staying on this important file.

    For me there is no debate at all regarding industrial wind turbines causing physical degradation to families at ground zero, and beyond as turbines increase in size. They are hurting thousands of people across the world and cherry picked so-called science used by the wind industry is intentionally used to enforce, dismiss and ignore the harm which includes repeated serious physical assault on people’s bodies at any point in a day. The entire situation is a sad and telling comment on an extreme lack of integrity and compassion on behalf of the wind corporations and governments.


  9. Sherri Lange  

    Lorrie Gillis, thank you for commenting!

    You have been at ground zero helping impacted families in Ontario. You zero in on the absolute incoherent lack of response to complaints, and the irresponsible dismissal of the harm. Frustration grows, universally. We hear there is a revolt, legal in nature, in France now, a challenge to the EU. Hope that kind of legal foray continues and spreads in North America.


    Wind turbines: opponents harden their fight

    Associations and elected officials who denounce the “excessive” establishment of wind farms in France have decided to come together to bring their cases to justice and gain visibility.

    By Angélique Négroni

    Instead of acting in dispersed order, they are united. In their fight against wind turbines which, according to them, are disfiguring our landscapes in France, associations have decided to unite to attack. This first show of force came last month. Instead of a few volunteers who usually go to court, this time 165 associations have together filed an appeal. They all came up with a regional document targeting New Aquitaine, which contains worrying objectives.

  10. Sherri Lange  

    Response from Mr. Cooper to Dr Ben Johnson. (Abridged) With thanks To Dr Johnson for his comment.

    Case study D on the Technical Note highlights the issue of incorrectly using wake free wind data and the effect of wakes. The SCADA information gives information per turbine (rotor speed, power output, blade angle, wind speed and direction at top of nacelle) in discrete time intervals. When you have that information then you can determine the actual power produced by the wind farm over time. Take that over a day or a week/month/year one can determine the real power output. Normally that output is significantly less than indicated at the planning stage and therefore questions the “cost-benefit” analysis.

    Examination of why the wind farm cannot get to the stated power output opens up the whole issue of wake turbulence. That in turn may account for the operational life of turbines being less than claimed at the application stage. But of importance to the noise is the acoustic assessment assumes clean air to every turbine which is not the case when you look at the SCADA information. Subjecting a turbine to dirty (or imbalanced) air has to result in a different noise output. As the downwind air from one turbine has pulsations in the wake then so does the dirty air. Pulsations and dirty air on the inflow side of a turbine cannot produce clean air on the downwind side. So the acoustic analysis assumed on the basis of single turbine results in clean air and having the same clean air at the wind speed across the entire wind farm cannot be correct.

    Re setbacks. The best language is when people are not affected. The topography varies the results.

    In the case of the Waubra wind farm (128 x Acciona 1.5MW turbines) on level ground my testing and discussions with residents found a distance of about 4.5km. I suggested to one family they rent a house 5km away. They did and their problems dissipated so whilst they still had the family farm less than 2km from the turbines they bought land 5.2km from the nearest turbine, built a house and got on with their life.

    For wind farms elevated on ridges (using say 3MW turbines) the distance increases. Depending upon the sensitivity of the individuals the distance for no issues can be as much as out to 10 kms.

    Response from Mr. Cooper to Jon Boone, again, with thanks for his comment.

    On a technical point there is a difference between infrasound produced by a wind turbine and the pulses that are generated at an infrasound rate. The papers presented in Germany last year at the ICA identified the incorrect use of “amplitude modulation” by persons not understanding the definition of amplitude modulation. To get to the bottom of the incorrect terminology has taken a few years and presentations both in the US and Europe. The variation in the dB(A) level cannot by definition be amplitude modulation, because the dB(A) is not a single frequency.

    The correct term is modulation of the amplitude at an infrasound rate.

    Under Zwicker and Fastl the ear responds to the modulation of the amplitude not necessarily hears the sound (when the pulsing occurs below 10Hz – which Zwicker and Fastl called fluctuation).

    Zwicker and Fastl determined the effect of fluctuation using a 1 kHz tone that was modulated and different infrasound rates. In the 1990s, Bradley used broad band low frequency that was modulated at an infrasound rate and found the same critical frequency as Zwicker & Fastl. Bradley expressed the difference in annoyance and showed a 2Hz modulation rate of the low frequency noise required a penalty adjustment of up to 17 dB.

    You can create a wind turbine signal in the laboratory and have absolutely no signals below 20 Hz – but the analysis will still give the infrasound signature of the blade pass frequency and harmonics of that frequency. It is simply the FFT analysis of a pulse.

    You can apply that signal to the ear (i.e. a broad band signal pulsed at an infrasound rate) and get the results Prof Salt did with pure infrasound. He was correct in the result but was it was from the pulsations.

    As to the final comment I find it amusing to use the term wind farm as seeing them planted in the ground I have never seen any new baby turbines grow up. Unfortunately that is the terminology use downunder in EPA guidelines.

    Comment by Lange: we use the word, “farm” when liaising, communicating with Europe quite a bit, because it is their common language for this, noting of course the irony, that there are no bucolic pictures of cows, and landscapes, and productive nurturing of animals and wildlife….however, the prevailing language in North America, in our “groups” and individual work and writing, is that they are indeed factories. When NA-PAW was working on a TVO (TV Ontario ) slide deck for an animated overview of turbines, the producer wished to use both, half and half, “farm” and “factory,” in order to satisfy all audiences!

    Thanks, both Jon and Steve, for the clarification(s).


  12. Sherri Lange  

    Michael Spencley, thanks for the comment. I deeply resonate with your fatigue with the failed so called studies and conclusions of the World Health Organization, and the ubiquitous Health Canada ….Noise and Health Study into impacts of turbines, concluding of course, only a little annoyance. For a few.

    “Both the WHO 2018 Guideline and the Health Canada Wind Turbine Noise and Health Study are being used by developers worldwide to satisfy meaningless compliance standards.”

    The utter failure of the HC study has been widely documented, but we continue to see it used by developers in zoning board applications, power siting boards applications, professional papers by the industry, and so on. Please see these references refuting its usefulness and displaying its lack of intellectual accuracy.

    Dr Robert McMurtry, in communication to NA-PAW, and published also by WAUBRA, Dr Sarah Laurie


    NA-PAW, McMurtry, Denise Wolfe and media release


    One can list more objections to the HC study, and indeed, even last week, a politician in Ontario used reference to it as a reason to hold on heels, any movement to assist victims of wind, existing.

    The amount of knowledge lacking in political policy making spheres is staggering. I really like your view that this Cooper series of papers should meet the eyes of President Trump, and that Mr. Cooper should be able to advise on wind turbine irregularities, if you want to call them that euphemistically, and that Cooper may shed light and influence at the highest level.

    Given events world wide in the objections and fights against the blight of industrial wind, it is certainly time to go up the ladder!

    Thanks again for your excellent comment.

    We tend in France to replace farm in windfarm by Centrale which recoups the American factory.
    Centrale éolienne is the translation for windfactory. Wind turbine factory.
    On the subject of compliance I was surprised to see Australia subject to British ETSU. Time to declare independence from a broken standard and fund a totally independent aussie standard. The UK will just raise hairbrows. Mr Cooper in charge of the new body based on reality and not predictions or averaging.

    Yes we are attacking the SRADETT in court. There is one for each region of France. The main issue is the French landscape. Unfortunately the health factors are not on the fore. So you see the wildlife and the landscape having more importance than the people ‘S health!!!
    A perverse situation. The Courts are way beyond the real problems of health, family disruptions etc. But we will push on relentlessly.

    The acousticians in France are undertrained and the wind industry sucks up the best of them. Their papers never reach the Australian level. They mesure and that’s it. I compare them to such as Robert Rand who observe and link frequencies and symptoms. They are not ethically responsible at all. I suggest that some Australian professional come to French universities and create an acoustic discipline based on their own standard. Thanks for your brilliant demonstrations of Science and ethics. Without you people beyond the seas we will never win!

  15. Sherri Lange  

    Thank you, Bawde…..interesting information on “farms,” wind turbine factories, and much more. The more we call them “factories,” the clearer the impression will be of the true nature of the beast. In AU, as you likely know, they are still referred to as “farms,” for the most part, and Mr. Cooper may have difficulty as an acoustic professional of the highest order, to suddenly call them “factories.”

    You say: “Time to declare independence from a broken standard and fund a totally independent aussie standard. The UK will just raise hairbrows. Mr Cooper in charge of the new body based on reality and not predictions or averaging.”

    I completely agree. Mr. Cooper and Rand and the others he lists in the interview, Metalka, Rick James and so on, have the handles of the machine to fight this, because of their absolute clarity and devotion to facts. I can imagine using this latest work of Mr. Cooper’s, and he has more nuggets coming, to impress certain rare honest politicians and policy makers, and we can use this knowledge to shut down non compliant machines which really, is all of them. The courts everywhere seem to be tokens of the system that creates them, unfortunately.

    We wish you complete success in France! Just read this today, and translated the entire article this morning:

    Wind turbines: opponents harden their fight

    Associations and elected officials who denounce the “excessive” establishment of wind farms in France have decided to come together to bring their cases to justice and gain visibility.

    We wish you God Speed in your fight. You inspire us all.



  16. Sommer  

    The reputation of the WHO needs to be seriously examined.


  17. Sherri Lange  

    Ms. Sommer…Yes, the WHO needs to be reassessed now on many levels. I recall the two year gathering of professionals who were applying to the WHO for inclusion of noise impacts, which turned out quasi successful, with large gaping holes, in the 2018 Noise Guidelines for Europe. I personally don’t think there is much/any cred there anymore, because of apparent allegiances in the COVID emerging story, and collusions, and wrong headed advice. It’s actually scary.

    From the Daily Mercury in AU

    “The World Health Organisation is facing growing criticism for its handling of the coronavirus pandemic and its ties to the Chinese Communist Party.

    A Change.org petition calling for the resignation of WHO Director-General Tedros Adhanom Ghebreyesus has nearly reached 700,000 signatures.”

    It goes on to say, the WHO has no longer has any credibility to lose.

    Thanks for commenting.


  18. Bawden  

    Mr Sherri Lange you are top notch as well.
    The Who being criticized in various disciplines. Note the onslaught of Pr Martin Pall on the Who refusing to acknoledge the non thermic effets of electromagnetic frequencies on the biological organisms and the subsequent deterioration after exposure.
    Note the experiment with patients with four times the normal dose of HCQ hydroxy chloroquine…
    Here in France the old lady in charge is Anses. As foolish as can be. And subtracting PR Alves Pereira as she is too dangerous for them. Old country Old Justice system and a new Prime Minister bent to the whims of the Great Manitoo!
    We all endorse the Gilets Jaunes in our struggles against the turbines, abhor Big Pharma who make money with anti. Vertigo pills for turbine victims. This turbine business pays some handsomely. The Germans from the wind lobby OFATE are ensconced in the Prime Minister Office, unelected and all powerful.
    It’s Nazism triumphant! Thanks God the people from Germany start opposing the turbines! And Research is emerging from their universities. We have no research here as such in acoustics. These acousticiens who speak at conferences from time to time in front of an elite audience are obliged to dig up whole transcriptions of Mr Cooper, lifting his graphics and all, to exain things. They never set foot in a lab.Never had a concept to develop. It’s just the bottom of the pit in here! Just terrorized by voicing the slightest criticism against the state and its mad expansion of turbines.
    So come on to civilize us Mr Cooper and those brilliant colleagues. We are sinking in the mist of a complete cesspit of ignorance and intoxication by the captured media/mafia and in the meantime our health deteriorates like in the north of France.


  19. Sherri Lange  

    Thank you so much, Bawden. What an eloquent overview, and survey of the littered landscape: littered with greed, overreaching power grabs, corruption, lack of knowledge, and Big Pharma in on all the health aspects, which is playing out nearly everywhere now. WHO is a colluder, a provider of falsehoods, if you ask many of us, and ultimately responsible for its false authority. Praise goes to those who stand up to this tyranny, such as yourself and the Yellow Jackets. If you could please communicate with me on Facebook, I would appreciate knowing you and your fights more deeply. Yes, thank you for Steven Cooper and his mentioned favorite acousticians, who tell us precisely what is required to know, how to understand very complex facts, explaining the nature of the turbine lies, and essentially giving us a road map….I am sure many are watching his thoughts and research, and I hear that communities are already ramping up actions or activities based on the falsehoods/misconceptions he is exposing.

    Juxtapose the clarity of Mr. Cooper with Ketan Joshi, a devotee of industrial wind:

    Quote from a previous MR article:
    Walking Down the Street?

    In an recent and astonishing display of wind industry innuendo and bravado, Ketan Joshi, Research and Communications Officer for Infigen Energy, published a blog on February 3rd, 2015, entitled, “Is Walking Down the Street a Major Health Risk? The fanciful premise, that walking down the street is in somehow equivalent to the painful experiences of wind victims, is frankly, the extreme end of myth: No one really expects that following the imaginative title that a stronger sense of fact will follow.

    What does follow, is the inevitable reference to the highly erroneous Health Canada “study” survey, widely questioned and by many discredited, with its highly selective and secretive data, not yet released, and its ubiquitous references to “annoyance.”

    Mr. Ketan further expresses that ”we’ve found that the overwhelming majority of people that live near turbines are very happy with their presence.”

    End of quote: not much to add here, as it is obvious that some of the wind supporters use pure imagination to support their affections.

    Thank you again for commenting.
