I congratulate Seneca County for being selected to participate in one of the largest experiments to determine the effects of infrasound on human organ systems. With large numbers of massive wind turbines planned in this densely populated county, medical effects on internal organs can be analyzed.
The size of the proposed wind turbines ensures the generation of low-frequency infrasound. The proximity of wind turbines to schools guarantees that as children age, internal organ deterioration can be compared to child control groups from similar demographic locations lacking wind turbines. After 10, 20 and 30 years, researchers can evaluate effects on human internal organs from infrasound. This is important, because western scientific research and medical literature has little written concerning short, or long-term infrasound effects on human organs such as lung, heart and kidney.
However, infrasound effects on internal organ tissue have been studied by numerous researchers in the former Soviet Union. They found that infrasound waves cause significant changes to heart tissue and other internal organs.
In the 1990s, European investigators studied internal organs in animal subjects and human workers exposed to infrasound. They found significant changes in lung tissue and heart pericardium. The authors also were concerned with potential damage to internal kidney structures.
In January 2018, German researchers presented results concerning infrasound effect on cardiac tissue contractility. They found cardiac tissue exposed to infrasound decreased tissue contractility by 25 percent.
Seneca County wind farm companies state that wind farm sound levels will only approach 55dbA. That information is misleading concerning infrasound. The“A” designation is a filtration formula including only audible sound between 20Hz and 20,000Hz. Infrasound is defined as occurring between 0-20Hz and is not identified with the dbA formula.
With multitude turbines planned, decibel level determination may be problematic. Overlapping sound wave energies add together, similar to overlapping ripples on water from multiple stones dropped simultaneously. Some waves cancel out. Other waves enlarge. Wind turbine numbers become directly proportional to infrasound wave energy multiplication. Also, infrasound waves are stable, traveling great distances.
For those interested in their own personal research on infrasound effects, information was obtained for this letter from the PubMed website (Key words: infrasound AND heart, or infrasound AND physiological effects) and the Wikipedia website. Soviet research, translated from Cyrillic, was obtained from the archives at The National Library of Medicine at the National Institutes of Health, Bethesda, Maryland.
