Yes, same here. The Hum was Very Loud and the Vibrations were Really Bad here in Northwest Georgia for about the past 2 weeks. Yesterday it calmed down considerably. About 2-3 now on the scale of 0-10.

It sounds most like 72 or 74 Hz, but instead of being a steady sound as is on the link, it has a more random undulating to it where it gets very slightly louder then softer...or maybe it goes between 72 and 74??
It was VERY loud for about 2 weeks and is now gone! So... I am going on memory instead of actual comparison.
