Weird! I wonder if it is ELF (extremely low frequency) noise...

  Speaking of which ... Does anyone else hear, on occasion, very low-pitched drones? As if there was a very large machine nearby humming away, yet at no discernible location? I've experienced this for years, in multiple locations, and have decided it is some form of tinnitus, but sometimes wonder if it isn't some external event.

    That is indeed tinnitus. I've had it for a long time, especially when listening to violing concertoes certain tones would sound very ugly in one ear and nice in the other. It's gone now tough (and I can't tell you how happy I am because of it, listening to music is one of my largest pleasures in life). I had an ear infection and it took years before my hearing was back to normal in that ear.
