BWC 850 Unloaded SPL. Linear regression trend and data from one-minute Leq with the turbine operating unloaded. Noise increases steeply with wind speed due to pulltruded blades. These measurements were made in winds below furling speed. In contrast to the measurements on the Air 403 or the BWC 850 when charging, the data is surprisingly uniform.
