Do yourself a favor and visit one of the large wind farms before
making snap judgements. I've seen several that were very impressive
and the people that lived near them had no issues. Here is one of
them:

The background noise that you hear is wind on the microphone.

What causes the "thump" ?

The displaced air. It is a low frequency pressure wave. You really
feel it as much as hear it. I suppose a lot has to do with the pitch
of the blades because it seems to come and go. We stopped outside
Minot SD and watched the two they have there for longer than my wife
was happy about but it was really a nice day, cool with a nice breeze.
We walked around them a while and I shot some pictures. That was one
of the places that I saw one being feathered and restarted a few
times. It really looked like they were using it to balance the grid.

The air would be displaced at a constant, round pattern, though.

You'd think so but the blades may spin off tip vortices, or somehow
interact with the supporting pole in some asymmetric way.

Yes, it sure could, but again, I've been quite near the new types and
never heard a sound. The prevailing wind was quite calm, but it was
louder in my ears than anything coming from the mill.
