I'm not sure whether I have misophonia, but I can certainly identify with what you're describing. Bass hasn't bothered me much, nor have pen noises, but dishes - I take it upon myself to do the dishes in my house because I can't stand the sound of plates scraping against one another when others do it, or especially glasses tinging against one another, which seems sharper, though each have their own special irritating qualities. I'd sooner take the time to do it soundlessly and carefully myself, even if it takes longer. I might wonder if I am shorter than my younger sister because she kept me from getting adequate sleep throughout our childhood due to the sound of her feet rubbing together in a dry, skin-on-callused-skin, chalky way, floating up to grate at my nerves from under her blanket (I spent much of this childhood held captive nights in the prison of the top bunk of a bunk bed that we shared). I am loathe to eat when surrounded by others who chew their food loudly, though the loud watery background music they play in restaurants usually drowns it out and - aside from my youngest sibling, my little brother - my family has excellent table manners and takes small, manageable bites that aren't so loud. My father has these loud, toad-croaking hiccups that have been known very effectively to reduce me to silent, inward tears when they persist for very long. Generally, squelchy and phlegmy sounds make me very uncomfortable, with very few exceptions. One is when elderly women dispense hand sanitizer from those purse-sized travel bottles into their soft hands and it sort of just runs all over their hands and squelches a lot instead of the alcohol drying it off like it's supposed to. It's like your skin chemistry changes as you age or something.
