The large ones made by Vestas and Siemens on wind farms out in the gorge aren't very noisy... The wind makes more noise than the turbines from about 50 yards away. In that particular area, I've heard that most landowners are happy with them since they get a decent lease payment for the land they're sitting on, and since they don't take up very much space on the ground they can still grow crops or graze animals.
