Human Vertigo Response to Wind Turbine Infrasound in a Controlled Laboratory Setting
Presentation Description: I could serve on a panel or as a speaker on any of a number of hot topics arising in wind permitting in Minnesota, including on (1) the complications of permitting hybrid solar/wind/storage projects, (2) our somewhat controversial total ambient noise standard (in particular, complications involving how to best isolate wind turbine noise from other background noise), on (3) bird and bat monitoring changes (4) FAA lighting mitigation trends, (5) repowering project set back issues, and (6) stakeholder engagement best practices from a regulator view point.
Finally, if you are interested in a more academic research topic, due to ongoing complaints by some residents living near wind farms and others, I worked with the University of Minnesota to secure funding several years ago for a controlled laboratory study of the characteristics of infrasound from wind turbines and their potential health effects. (Most studies of health effects to date are surveys of nearby residents.)
In one of the only studies of its kind, University of Minnesota researchers recently completed a controlled study of human vertigo responses to infrasound generated from a wind turbine, recorded at 600 meters and re-created in the laboratory.The study consisted of testing seventy healthy adults ages 21–73 years for vertigo symptoms from modulated and unmodulated audible sound at 50 dB, as well as recorded and peak-enhanced infrasound at an overall level of approximately 85 dB (peaks up to 95 dB). Participants were tested for their postural stability, detection, and ratings of audible and infrasound emissions from turbines. No significant adverse effects from healthy adults were noted. Some individuals reliably indicated detection of infrasound signals.
