It's so hard to wrap my head around that.
I understand how you feel exactly. Thing is, I grew up in a dense area where around July 4th, people would set off M80's and other loud fireworks all the time. Never gave it much thought and not once did I experience any negative effects from being in fairly close proximity to said explosions at the time (and never set any off myself, wasn't a fan.) This was years ago now and haven't been around noise like that since. My incredibly loud and unmaskable tinnitus started all of a sudden one day after living the quietest three months of my life in rural Virginia, a far cry away from what my life was like in New York City and the surrounding suburbs. So like you said, it's hard to wrap my head around it.
Tinnitus is a beast of a thing and apparently doesn't care how it strikes. I've read a lot of your posts and it seems like the sounds we hear are very similar; wavering electrical tones and all that. I hope in time we get better.
