I would talk to an audiologist about this disorder. I have autism and with most people with autism I have sensory disorders as well, but not all of them are diagnosed. I probably do have this disorder because I absolutely can not stand mouth noises and they make me irrationally angry or give me anxiety. I noticed in my teens that being so angry and hateful towards simple mouth noises was abnormal since no one else was ever bothered by them. I just assumed it was disordered sensory processing from my autism that caused it like how I am super sensitive to temperatures and need my room to be at least 75 degrees for my hands/feet to not be cold.
