Whilst we are acutely aware of noise issues from wind turbines, substations and overhead lines, it is sometimes pretty pointless to make them an issue as the DECC works with eskewed and corrupt noise standards in ETSU-R-97 and the new replacement standard and because of that Inquiry Reporters or Planning Inspectors routinely refuse to even consider it in PLIs. Slowly the worm is turning and a whole load of peer reviewed research is making the government and the DECC/Energy Consents look more stupid by the day. The Day of Atonement is coming!
Very low frequency sound generated by commercial wind turbines can have negative affects on human health, according to research at Washington University School of Medicine.
“Even though it can’t be heard, we know this type of sound is stimulating the ear quite strongly,” says Alec Salt, PhD, scientist in the Department of Otolaryngology at Washington University. “We’re now looking for how that could potentially affect people and cause symptoms.”
Salt describes “infrasound” as being about 10 keys below the lowest note on a piano. Unlike ultrasound with its short wavelengths, infrasound is characterized by very long wavelengths that stimulate the outer hair cells, the ear’s amplifiers. The inner hair cells, responsible for hearing, do not respond to infrasound. Therefore, like ultrasound, infrasound is generally outside the range of human hearing. It is still stimulating the ear and the brain; it’s…
