6:45 AM. Wind N, 18.6 rpms. The noise outside is like a low flying jet going over. An actual jet sound would be gone in 10 to 20 seconds. The turbine jet noise goes on for hours and for as much as 4 days. I don’t want to limit the approximation to 4 days because it could be longer. I woke up with a headache. I was woke up 3 to 5 times last night.
10:10 PM. Wind NW,18.0 rpms. Turbine 4 sounds like a jet taking off.
