I have a hard time if LOUD music is playing and people are trying to talk over it. It makes me dizzy.
We live by a major hwy and the sound of the loud cycles going by one after the other really makes me cringe. Sometimes there's 20-30 in a group.

I don't have anything against the bikers, just the constant roar makes me go inside the house. I'm getting old!

Oh, and loud snoring pushes me over the edge. Thank goodness DH stops when I roll him over on his side.
