Its not just LOUDNESS to consider mon ami, its wether its high pitched " fast" noise or the less intrusive Low pitched "slow" noise, I small highspeed turbines higher pitched noise can sound very annoying like a lawnmower, but some models with larger blades and different gearboxes sound more like the wind blowing or sea waves rolling onto the shore, ie not as intrusive. His info is reasonable for one specific reason that I will guess at not having visited your home HL. But in a windy hilly area like yours the background noise from the wind and breeeze rusting though the heather and trees will make about 35 DB anyway. The last wind noise tests I did on a WF were in north northumberland and even without a WF the wind itself blowing through the area generated 35 DB.
