I'm also quite a loud person without being aware of it. When I am trying to be quiet I can do that for about 5 minutes, but then I forget about it again. I wish I wasn't this way because it is annoying for me too, since I don't like to be this noticable.
I am also very clumsy, which is something I have absolutely no control over. I accidentally hurt myself, bump into things, drop stuff, walk into people, slam the door a little too loud without wanting to. My body coordination just isn't good and it gets very bad when I'm very dissociated.
Weirdly and ironically, I am also annoyed by loud sounds. I know thats not fair because I often am loud myself, but I'm just very jumpy, easily scared and hate certain sounds (btw, have you heard of misophonia?).
Because my ex was smoking regularly, he was often coughing multiple times each minute, and it drove me mad. But there was nothing I could do, I could only work on my anxiety and anger issues. I couldn't expect a person to just magically be the way I wanted them to be, I had to work on myself, you know?
Hope that you'll be able to be a bit more regulated around people that make annoying sounds❤Believe me, I understand the struggle.
I just had a thought - is it possible that you are annoyed by attention seeking people in general and not by loud sounds per se?
