“The inaudible noise from wind turbines” is a very interesting study of the German Federal Institute for Geosciences and Natural Resources (BGR), headquartered in Hanover. It examines how infrasound from wind turbines may disrupt sensitive stations. The BGR operates inter alia the infrasound station I27DE in the Bavarian Forest, which is part of the International Monitoring System (IMS) to monitor compliance with the Nuclear Test Ban Treaty. With a series of measurements, the Institute wanted to clarify what distance wind turbines should have in order not to disturb the infrasound monitoring system therefore. As a by-product, the scientists developed models of required distances from wind turbines to residential areas. Continue reading →
