Could that be related to other maritime noises, like waves or seagulls?

I walk through one of these eyesore fields regularly, and I can hear them easily from 200m away.

I like the wind farm views. It's very subjective of course. Though most people don't like change, and since old power generating stations were high density (eg. a coal plant, just a big building and a smokestack) the new low-density things are naturally running into this change resistance.
