I've had it since I was four after two severe ear infections. I also have visual snow which is a common comorbity to my knowledge. It sucks never being able to have silence again, and I get spikes when my sleep quality is poor or inflammation is high, but I've 'habituated' I guess. Also have noticed a general, if subtle, decline in my hearing that is seemingly out of my control, but it's definitely happening.
The tapping behind the ears trick (hard to explain) can make it quieter for a few minutes in my experience, but other than that, I feel your pain. I relentlessly tell people to protect their damn hearing because it is painful constantly being on the receiving end of volumes too loud, and because hearing loss and t are not fun regardless.
