I couldn't stand noise, listen to music, tolerate the phone ringing, etc. sitting at a red light if a car pulled up with heavy bass thumping would at my pain off in a split second. I do not know what caused the change but about two years ago, I was slowly able to start listening o music. I can't operate everything.though. Calmer, soft voices an melodic music ok, more complex, loud, disjointed stuff, not ok, but sensitivity to sound and smell and vibration or movement is absolutely normal.
