That's perfect. That's what I do, more or less. I still feel really stressed out in the first 5 minutes after and I avoid unneccesary loud noise of course, but if it happens I try to move on immediatly and not put too much emphasis on it.
I try to separate my emotional response from loud noises and T. If I worry or think about getting a spike or increase then I'll perceive it as louder. I'm careful like most around loud noises and exposure though.
