Pulsing Punishment: Wind Turbine Infrasound Delivers Perpetual Torment for Neighbours

The evidence proving the unnecessary damage done to wind farm neighbours by the noise generated by giant industrial wind turbines is mounting by the day: Germany’s Max Planck Institute has identified sub-audible infrasound as the cause of stress, sleep disruption and more (see our post here); and a Swedish group have shown that it’s the pulsing nature of low-frequency wind turbine noise  (‘amplitude modulation’) that is responsible for sleep problems in those forced to live with it (see our post here).

Now a team headed up by Dr Mariana Alves-Pereira takes the research a step further, as outlined below.

Abstract
Within the context of noise-induced health effects, the impact of airborne acoustical phenomena on biological tissues, particularly within the lower frequency ranges, is very poorly understood.

Although the human body is a viscoelastic-composite material, it is generally modeled as Hooke elastic. This implies that acoustical coupling is considered to be nonexistent at acoustical frequencies outside of the human auditory threshold. Researching the acoustical properties of mammalian tissue raises many problems.

When tissue samples are investigated as to their pure mechanical properties, stimuli are not usually in the form of airborne pressure waves. Moreover, since the response of biological tissue is dependent on frequency, amplitude, and time profile, precision laboratory equipment and relevant physiological endpoints are mandatory requirements that are oftentimes difficult to achieve.

Drawing upon the viscoelastic nature of biological tissue and the tensegrity model of cellular architecture, this chapter will visit what is known to date on the biological response to a variety of different acoustic stimuli at very low frequencies.

5. Conclusions
Exposure to infrasonic and lower frequency airborne pressure waves can cause cellular and tissue damage depending on frequency, dB-level, and exposure time, while the viscoelastic properties inherent to biological tissues impart a nonlinear response to this type of acoustic stressor.

The complex mechanosensitive and biochemical cellular signaling pathways mediating this cellular damage have not yet been pinpointed, although fasciae structures and connective tissues (including the neuroglia) seem to be the most sensitive under longer term exposures. Immediate exposures appear to induce inflammatory processes that do not seem to be maintained with longer exposures.

Widespread vascular involvement (not limited to the biological structures addressed herein) was observed in palpebral and bulbar conjunctiva and retina, gastric mucosa, liver structures, lungs, pleura and tracheae, alveoli, pericardia, and coronary arteries. This vascular response may (unsuspectingly) be the underlying cause of many symptomatic complaints.

Cognitive deficits oftentimes documented within residential field laboratories may not merely be due to sleep deprivation, but also to hippocampal neuronal damage. Fasciae morphogenesis speaks to the demand on the whole-body structural integrity elicited by this type of external mechanical insult, while collagenous growths and hemorrhagic events of a focal nature may reflect concomitant resonance phenomena.

Recovery periods are not linear, and 2-hour daily exposures imply a 22-hour nonexposure period. This presents a problem for continuous exposures, such as those encountered in some professional activities and most residential environments. The underlying objectives of most of the studies discussed herein are related to occupational exposures and do not consider continuous exposures at less than 90 dB, nor are pressure pulsed trains presented within the laboratorial acoustic environments.

In residential environments, however, these attributes are often present. The simulation of residential exposures does not appear to have yet been integrated into laboratory settings and protocols.

The whole-body response also elicits the immune system, affects organs of the reproductive system, changes receptor cells in the vestibular semicanals and auditory cochlea, and induces genotoxic effects, including teratogenesis.

This is a pioneering field of science, still in its infancy and urgently requiring scientists from multidisciplinary areas of study because, ultimately, the health of human populations and their offspring must be protected.

    Birgit Hermes, congratulations on your excellent video on infrasound and it’s health and social impacts on the people of Germany, the millions of them. As one of the ten to thirty per cent of people adversely affected by infrasound from wind turbines I am one of the un-housed neighbours of the Cape Bridgewater Wind Farm; also, as mentioned by the German family, have been ignored by authorities to be “left in the lurch and betrayed”. Independent acoustic work undertaken at CB by Steven Cooper, Dr Bob Thorne and Les Huson gave clear warning to the Victorian Government of the acoustic toxicity the wind farm causes inside our homes and on our properties. Meaningful and ground breaking acoustic and medical research is much appreciated for it’s factual honesty and which supports those of us in deplorable situations where we neighbours tend to be wrongly cast as either hysterical nimby’s or liars and worse.
    Pacific Hydro and the National Wind Farm Commissioner have repeatedly turned a blind eye to the evidence presented to them and have failed to rectify the wind farm operational faults causing the ongoing distress, health and economic issues for affected neighbours like myself. ”When you cannot hear infrasound it is more dangerous”. It leads to complacent or ignorant and wilfully blind attitudes allowing the harm to continue. When you cannot hear infrasound, you feel it and in the Cooper Study at CB these unheard but felt detection’s were categorised as sensations and were graded on a scale of severity from 1-5. A level five meant you had to leave the house because of the intensity of the sensations. The conditions are so bad that three of the Cape Bridgewater families have been forced from their homes and more would if they could.
    Only those being kept in ignorance of the detrimental impacts of wind farms could accept ‘payments’ and in light of the work by Mariana Alves-Pereira, Bruce Rapley, Huub Bakker and Rachel Summers, Professor Salt and the German Institute and the many before them; you’d have to be wilfully and evilly ignorant to perpetuate wind farm harm and wind turbine syndrome by continuing to build wind turbines too close to people.

    In breaking news, the Lovely Audrey was last seen this evening running down St Kilda road heading for Pt Philip bay in nothing but a leopard print bikini and Jimmy Choo high heels screaming “the sky is falling, the sky is falling.”

    She was closely followed by Charismatic Kane on a carbon fibre bike, grim faced and mumbling something about climate change effecting the performance of his tyres.

    Dear Angus,

    Having the Lovely Audrey in charge of the Australian electricity market is a bit like having Ivan Milat running Australian Contiki tours.

    Come on Angus, you cant have a zealot running the show.
    Obfuscation of the facts, closing down industry in hot weather, exorbitant pricing and the very grave risk of citizens dying.

    We have zealots like the renewable energy Messiah and Yoda Yates condemning coal generators for a scheduled stoppage and maintenance.

    On hand they want coal working, on the other hand they don’t?

    A coal generator competes against subsidized wind, told its unwanted and no investor will touch it and then they wonder why there are small outages.

    Meanwhile they dare not mention that during the peak of today’s heat wave coal and gas were chugging away producing 27,000 Mw/h of generation with a peakdemand of around 36,000 Mw/h.

    Yet the elephant in the room, wind energy was producing a measly 1000 to 1500 Mw/h, with an installed capacity of around 5000Mw.
    It makes you wonder whether the Messiah and Yoda have suffered from their very own personal form of “load shedding.”

    Angus, today’s events in the Australian electricity market illustrate how futile the cries for more renewable generation are.

    STT, I and others can do no more.

    Cometh the hour, Cometh the man.

    Angus, it’s time to bring on more base load generation, yes there will be an uproar by some and it might even cost the Libs an election.

    At the end of the day you have to ask if you don’t take on the zealots, you have to ask why you even took on the job?

    Why can’t we see these reports to the mainstream media and have the Giblet politicians in Australia been informed on a professional level. Could someone tell me?
