If something loud is coming, I need to know beforehand so I can prepare for it. Otherwise, if gives me a lot of anxiety.
I'm exactly the same! Let's say I go to a concert (not that I ever do, but still), I will know beforehand that there will be lots of noise. Of course, it will be tough, but I'll be able to endure it. However, if I go into town and people suddenly start screaming and hooraying and clapping I will panic and get anxiety, as I don't know it beforehand and can't predict it. Not knowing is the worst thing for me, I can't handle it.
I do love listening to white/pink/brown noise when going to sleep, though. It is so relaxing. But I think that's pretty common?
