Statewide Iowa — (RI) — Iowa-based researchers have concluded there’s little scientific evidence that sound from wind turbines poses a public health risk. Instead, the authors say reported symptoms of hearing loss or poor sleep are more likely related to people’s attitudes about wind development.

The findings by the Iowa Policy Project and the Iowa Environmental Council are based on an overview of peer-reviewed studies. Co-author David Osterberg says reports of symptoms are associated with annoyance at developers rather than the actual sound of the turbines.

Wind turbines produce sound pressure, but Osterberg and his research associates concluded it’s not at a level that affects humans.
