Actually infrasound is pretty bad for you. At the right frequency around 18-19Hz you start seeing ghosts. Substantially lower can really do a number on you too.
Source only states effects on people working on the turbine, and, in general, people exposed to infrasound at volumes higher than those you get from having a wind turbine nearby. You practically have to be on the device.
