There’s been a German study and please don’t ask me to find the pdf but the basic comparison was between comparable installations in the north and in the east, major difference between those categories being whether they were owned by a local citizen coop or a big company from whoknowswhere.

Long story short: If the blade swooshing sounds like “cha-ching” it actually lulls people to sleep.

As to shadowing though yes that can definitely be nasty. Luckily we have the science necessary to predict where the sun will be and can build the windmills such that moving shadow don’t hit homes at all, or only for a minute a couple of days a year or such.
