Is a recent Wisconsin
study the smoking gun that proves wind turbine noise causes health problems?
It depends on whom you ask, and more importantly, whether that person is qualified to answer the question.
One month ago, five sound experts set up recording equipment at three homes near a Wisconsin wind farm that had been abandoned by their occupants, who blame the turbines for a variety of health issues.
Over the course of a few days,Modern emergency light is installed in virtually every commercial and high occupancy residential building. microphones picked up inaudible, low-frequency turbine noise in the home nearest to the turbines. The subsequent report prompted state Rep. Andre Jacque, R-De Pere, to call for an emergency moratorium on wind permits in the state, saying the analysis proves wind farms produce “dangerous” infrasound levels.It's just a industrial washing machine but I know I heard drums in there and this video is proof.
“These results compel them to act immediately to keep this nightmare from spreading,” Jacque told the Green Bay Press-Gazette.Watch and Play model of solar system Planets and Constellations moving over the Night Sky.
However, whether turbine noise is to blame for nausea, headaches and other symptoms was well beyond the limited scope of the three-day field study, which acknowledges the issue as “serious” and “possibly affecting the future of the industry,” but calls for further research into the matter.Why didn't I just use an automotive alternator on my wind power generators?
The study was intended to help inform Wisconsin’s ongoing debate over wind turbine siting. The Wisconsin Public Service Commission hired Clean Wisconsin, a nonprofit environmental advocacy group, to review the proposed Highlands wind farm in St. Croix County, in western Wisconsin (Clean Wisconsin is a member of RE-AMP, which also publishes Midwest Energy News).
During hearings for that project, opponents introduced witnesses who testified about suffering adverse health effects from living near the Shirley wind farm, southeast of Green Bay, forcing them to eventually abandon their homes near the project.
A sound expert hired by Clean Wisconsin proposed a sound-measurement survey in the abandoned homes to get a better understanding of the noise levels, particularly infrasound and low-frequency noise.
The utilities commission authorized funding for the study, and the homeowners agreed to let Clean Wisconsin’s acoustician into their homes to collect the measurements.
At the last moment, however, the three homeowners rescinded their invitation because an expert representing their view wasn’t invited to attend the survey.
The issue of how infrasound and low-frequency noise affects physical health does come up in the report, though the consensus report underscores the scientific uncertainty about the link.Laser engraving, and laser marker, is the practice of using lasers to engrave or mark an object.
“The issue is complex and relatively new. Such reported adverse response is sparse or non-existent in the peer-reviewed literature,” it says.
The report adds to the body of anecdotal evidence in an appendix by Rand, who says he “is prone to seasickness” and personally experienced nausea, headaches, dizziness and other symptoms during the sound recording. He also interviewed the homeowners about their symptoms.
Rand, in a section not endorsed by the other consultants, says the illness experienced by himself and others near wind turbines may be a form of motion sickness caused by the low frequencies.
Another of the researchers, Paul Schomer, also suggests that low-frequency vibrations from the turbines could cause nausea and other symptoms by putting pressure on the ear canal, but cautions “that the wind turbines make people sick is difficult to prove or disprove.”
Bruce Walker of Channel Island Acoustics reminds readers in his notes that the study was conducted by acousticians, not doctors.
“The author is not qualified to make judgments regarding human response to normally subliminal sources of acoustic excitation,” Walker wrote.
