Maybe you have figured out a objective way to listen to, experience, measure and compare others tinnitus to your own? I would highly doubt it, and if not, your statement about "super loud tinnitus" or scale 10-11 means absolutely nothing to anyone in the real world, it only means something to you.
Most thing are subjective aren't they. Doctors frequently will use 1 to 10 scales for patients to fill out. And some tend to downplay and some exaggerate based evyen on mood,personality or any number of reasons. My ocd issues generally caused me to be conservative with those numbers just because it seems to me like complaining. One of the forms for balance therapy asked for percentages about level of confidence. There was nothing scientific about that (lol).
