Hi,

A couple of weeks ago  I downloaded a sweep wav file (10 khz to 20 khz)
to test out my hearing on the computer. I could hear to about 16.5 -17
khz on a lowish volume, being curious if I could hear beyond that I
paused to the point where I couldn't hear any more and cranked the
volume up (a lot). Apparently I could hear pretty well, as when I
played from that point the tone was literally deafening and very very
painful. I'm sure I caused some damage and probably lost some
senstivity to the high frequencies. But the worst problem I've incurred
from this inane experiment is the unbearing ringing in my ears, which
becomes a torture at night. I've could always feel a slight ringing in
my ears since I was a kid at night, but what I have now is unbearable.
Any advice before bofore I finally  drill into my ears? I've not gone
to see my doctor yet, as I've heard tinnitus is incurable. I'd
appreciate any advice here.

Thanks
