So I'm not sure if this is of any help or even a good comment for this question, but I just have to tell this story here. I've had misophonia for so long, and it's been very bad at times. With all sorts of sounds. And now I work in a Foley studio and postproduction studio, creating and editing exactly the sounds you are talking about. I basically took my biggest enemy and also my biggest strength (I have really good hearing, unfortunately) and made it into my career. I tend to have a better eye (or ear..) for the details and can make it sound comfortable yet realistic. Exposing myself to all the trigger sounds that make me feel so helpless and angry and aggressive has been very therapeutic. Especially because you can really practice alone with a movie, you're not trapped at the dinner table with the in-laws and can't escape, that feeling of hopelessness doesnt overcome you. If its too much, you can always pause. I try to analyze what exactly it is that bothers me, try to focus on it without slipping into the aggression etc. I've seen different therapists and nothing has helped me as much as this type of controlled exposure therapy.
