I see no mention of genetic predisposition to hating office noise. 23andme looks for a marker that indicates hating the sound of chewing, misophonia. Maybe something similar is at play for other noises.
Now I'm wondering if that's genetic and how many other people have the same experience with those sounds.
I don't think it has anything to do with the sensations themselves, just my brain perceiving the stimulus as abrasive / piercing. It causes some kind of psychological pain, and weirdly I did not have this problem until my mid-20s.
