BACK IN 2013, STEPHEN AMBROSE, Board Certified Member of the Institute of Noise Control Engineering and a Full Member of the Acoustical Society of America, testified in front of the Vermont Senate Natural Resources Committee: “Regulatory boards are now unable to protect public health and wellbeing because the wind turbine industry has substituted their own measurement and assessment procedures through international committees. “The wind turbine acoustic standards differ dramatically from other noise sources. Wind turbines are evaluated using A- weighted sound levels by removing all low frequency and infrasound from consideration. A-weighting lowers infrasound levels by 50 dB at 20 Hz and 70 dB at 10 Hz. This promotes false statements that wind turbines do not produce infrasound. “I have measured infrasound using a sound level meter and a microbarograph. I have experienced the adverse health effects caused by infrasound. Again, I felt miserable with a headache, nausea, loss of cognitive ability, sleep interference and interruption. “I felt better when only a few miles away from the wind turbines’ influence.” “I recommend that anyone who thinks wind turbines are good acoustic neighbors to do what I did. Go to a wind turbine site, live as a neighbor, and sleep in their bed when the wind blows strong.“ Read more: Testimony from an acoustician with 35 years’ experience
