It's funny that this popped up because I just got home from watching Captain Marvel. I know I have at least some tinnitus because my world sounds like the descriptions of it, but it's not so bad that it really affects my hearing. That said, I have noticed that some movies--particularly Marvel explosion ones in IMAX--sound much louder to me in my mid-30s. The higher sounds come across to me as sharp or shrill.

One nice thing about going everywhere with a backpack is I'm used to having earbuds with me so now, I just don't take them out of my ears when I get to a movie. I still hear everything and it doesn't sound muffled, merely...turned down, I guess, to a "good" volume.

I first hit on this when I forgot to take my earbuds out prior to, of all things, a Weird Al concert (his "Vanity" tour at The Moore in Seattle). I'd ridden the bus down there and had VIP tickets for the pre-show stuff so I sat and watched it with my earbuds in for listening to his music during the lulls in the pre-show activities. When Emo Phillips started, I forgot to take them out and realized after the show that my ears weren't ringing (louder than usual) and I didn't have the beginnings of a headache.
