My Sensory Processing Disorder is what got me on the road to my autism diagnosis in adulthood, it's bad.

And I've heard the "gotcha" about music and concerts so many times, especially since I too am a massive fan of "computer noises *" (honestly though classical music concerts are the worst offender because all you can hear is others around you clearing throats, coughing, opening candy wrappers.. It's like torture), but somehow only just recently the penny dropped - it's a stim!

So not only is it the choice thing and the fact that you can follow music vs how sudden/sharp noises just completely scramble your brain and all that other stuff, but also - it's calming to the nervous system (especially when you're having a sensory overload and putting headphones with loud music on is enough to block out the noise, never mind a defence against that in the first place), it's giving me something enjoyable to focus on, it's giving me these lovely sounds to vocalise along with (vocal stimming/echolalia, which can be harder with lyrics vs just music because words make you think), it's probably the only thing other than my cat purring that I can completely sink in to even if it's just for a minute or two to get a break from the internal noise in my head (doesn't always work, but nothing else does).

None of that helps explain it to the NTs though, more often than not when I try their instinct is to make as many horrible noises as they can, and not just then, but at random points later to "test" me, or worse, openly state that they are doing it to trigger me because they find my distressed reaction hilarious. A few do get it, and they try their best, but it's still a constant asking them to "please not", and if they can hear that without taking it personally and getting upset, then you know they can stay lol
