Sometimes they bother me more than at other times. If I'm feeling particularly sensitive in those regards, I've learned to be very careful with things like where to be and what activities to do (NOT ones likely to bring frustration) etc., because I noticed a correlation with exploding. The "tripwire" gets shorter.

Certain noises (yippy little dogs, kids whining etc.) always grate on my nerves immediately. I can't take strobe lights at all. Any sudden noise will make me jump a mile. But where I live is quite noisy (airport, sirens, trains) and aside from the sirens occasionally bothering me, it's fine. In fact, I think of the highway (a few blocks away) as white noise. Haha. Schshshshshshshsh.
