Just a soapboxy note, misophonia isn't just a sound you find annoying or gross. I find loud chewing gross but it doesn't trigger a visceral reaction. I found my dog licking himself for twenty minutes irritating but it doesn't cause me to freak out. Misophonia is more serious than just not liking something. Pardon my paragraph but I've seen so many misconceptions about misophonia.
Anyhoo, my trigger is humming. When I was a kid humming would make me clap my hands to my ears, scream, and cry. I have no idea what it is but humming sets something off in me. I had to learn how to control my reactions so I don't have total meltdowns anymore. I still freeze up but I can now politely ask the hummer to stop. I'm so glad that even though my boss is a musician on the side, he does hardcore bands with screamers. Not the nicest sound but hey, it's not humming.
It's pretty dumb but if I cover any songs with humming I change it to vocals because I can't do it. I've even had to ask music teachers not to hum to demonstrate pitches. My banjo instructor used one of those little tuner kazoo things to accommodate me.
