I have a request for non-autistic people, and anyone who does not experience sensory sensitivities: Treat sensory sensitivities as disabilities and accommodate them as you would for any other person who is pain. Believe Them.
I just watched the movie Sound of Metal and it is by far the most relatable experience of my hyperacusis and auditory sensitivity that I have ever seen and heard on film.
I have never understood why wearing headphones (i.e. listening to music, assuming) is considered rude or disrespectful. I hear just as well with headphones as a non-autistic person hears without them.
