Actually, my noise sensitivity, which caused me untold stress when younger, is better now. I think I have learned that "this too will pass." The tornado siren, the vacuum cleaner, these used to bother me a lot, now less so.
It's interesting, I have heard a psychiatrist caution that protecting yourself against sound using noise-cancelling headphones or avoiding noisy places can actually make things worse. If you occasionally expose yourself to the unpleasant stimulus, your nervous system learns not to over-react to it, or learns it's safe to ignore it. Now, I don't know if this applies equally to autistic people as to NTs. YMMV.
