Are we talking constant ringing or here and there?
It's obvious you're going to have ringing after a loud event, wearing headphones and having the music on loudly for some time, even a loud TV can
spark it up once you've switched it off - but that's quite extreme volume. So, had you been listening to music that night?
Another thing is general frequencies. Have you looked around your house, perhaps something is just making your ears "ring" or so it seems because of
it's frequency. TV's, fridges, computers and just normal phone chargers omit a dirty frequency that I know I can hear. I'm sure Im not the only one
who can hear that a TV is "on" in the house even if I'm nowhere near it. So I make sure everything is completely off at night, cos otherwise it
causes a frequency ringing. My XBox, modified, creates an ear piercing frequency - seriously, it can make you feel ill. A Bit like those yob alarms
that just play a high frequency.
Also I know a lot of friends including me get that random, OW, massive loud ring has just entered my head! But then dissapears a few minutes later.
God knows what that is all about. Ha, someone recently said on ATS that maybe ringing ears could be when a UFO is over-head, so I tested this theory
the last few times it's happened but no, didn't see anything. So I can't say that bit relates to UFO's in your area
Finally, there is always a bit of ringing in your ears. It's just how atune you're being to it at the time. I can hear it since I read this thread,
but not before - cos I wasn't thinking about it, even slightly

It's better now, but when I used to go to bed, lying on one side I would hear a
rythmic whooshing sound in my ear and a very low ringing. Turned on my otherside, I would hear nothing. It was hard to daydream or concentrate with
that sound. But I'm fairly positive that was just the way my ears work. Well good luck. If your ringing ears somehow manage to make contact with ET,
let us know!
