Both tests -- ABR and ECOG -- had perfectly normal results. I think I dozed off a couple of times; I remember twitching (the way one does sometimes, when falling asleep), I'm pretty sure I was dreaming at one point, and (I fear) I think I may have been snoring. *blush*

They did a third test that I didn't get the name of and said there seems to be some minor damage to the hair cells and that I should, you should pardon the mixed metaphor, keep an eye on my hearing.

So whatever is causing the tinnitus, it isn't something like a growth on the auditory nerve.
