It bothers me a bit to be using Ancient Greek terms to describe a modern 
"wind farm", however I doubt these are what we think of as generators, 
but are probably 3-phase brushless generators/alternators.

"My guess" would be they should be no more noisy than a power line, but 
that depends on how they couple the power from the source to the cables 
coming down the poles to allow for unlimited directional rotation.  It v 
may also depend on how well the system is maintained.
