Sound: my hearing is so good that I can hear my own hart beat, my own breaths, my head pawning, ear whiling, skin tubing, cloths rubbing, my own swallowing, teeth chattering, everything from my body I can hear in 10x volume.

No wonder why I like it alone by myself in a secluded space where their is very few sounds to deal with. NO wonder why I hate eating out or going to the movies or anywhere where their is lots of people. I hear everything at 10x so it is a amazing thing if I can respond to people under theses situations.
This is just me but it may be your kids to that have it just as bad as I do. Keep that in-mind the next time they have a melt down in public. they just have not learned to adapt to the mass amount of information their brains are trying to deal with.
