The wind industry is heavily invested in a propaganda campaign aimed at convincing the public -- and decision makers -- that wind turbine noise is safe at any distance. The campaign, in part, involves blaming neighbors and their negative attitudes about turbines for their discomfort while avoiding measuring the actual “swish-thump” of the spinning blades. The campaign also requires dismissing low frequency noise and for good reason. Former Vestas’ CEO, Ditlev Engel has admitted that larger setback distances are the only way to address low frequency and infrasonic impacts, particularly on larger (3MW) turbines. Bigger setbacks means fewer locations for siting turbines near where people live.
Vestas and others can complain, but the damage from turbines can no longer be ignored. There are enough turbines operating worldwide, and enough people impacted, for the public to recognize turbine noise is intrusive and potentially harmful to neighbors. Trivial reports produced by agenda-driven researchers in Iowa are unlikely to divert attention away from this fact.
