When I had a stroke I heard a deafeningly loud noise in my right ear, similar to a helicopter under water. I have high pitched tinnitus all the time, and pulsatile tinnitus sometimes, but this was much different and so loud it was unbearable. Obviously, I'm not implying you're having a stroke. Far from it! But, your question reminded me of that sound. When I have shutdowns or meltdowns I don't hear anything of the sort except for perhaps pulsatile tinnitus, if I'm really stressed, from adrenaline.
