No, it's still really quiet.
This is hard to describe, but I'll try. In the "vanity" photo I took on December 14, just to the right is the power service pole on my property. Transformer "jug" on top of the pole, meter and connection panel at the bottom. Typical. Now, have you ever stood beside one of these poles on a windy day? If you have, then you know they hum. The flow of wind over the high tension wires causes them to vibrate, and that vibration is conducted to the ground through all of the poles.
My point is, no matter where I stand, close to the turbine or close to the power lines, the hum from the power line is louder than the turbine blades. If it isn't windy enough to make the power lines hum, then there's nothing to hear either way. When it is windy, maybe I can hear the turbine blade tips whistle, but hard to notice over the drone/hum of the power lines.
The problem with this explanation is, I think I make it sound like the tower is close to the power lines. But it isn't (that would be stupid).
That's also why I can hear the cable slapping the tower rungs, even 250 feet away.
The situation changes when I'm at the base of the tower. It sounds funny, but it's also interesting to lean my head against a tower leg. Now I hear lots of stuff going on. But that's no different from the many-toned vibrations that I could listen to in my last tower. It's the same turbine so it plays the same "concert". It hums on a variety of frequencies. The stator slot vibration is obvious because this is a motor-conversion. Yawing motions might make a random sliding sound. There's a little 1/rev oscillation because the blades aren't perfectly balanced. I suppose if I was there in strong winds I might feel it when the tail furls on and off the stop - but it's winter and I have warmer places to be in a blizzard.
