Does anybody else remember when that gaming harness thing came out that would cause vibrations all over your torso whenever your character got shot and it started making people sick? Yeah, I'm still recovering from that. No need to simulate blowing out my eardrums too.
Flashbangs are enough with an expensive headset, i fire one bullet in siege w/o a suppressor and im deaf for 5 minutes flashbangs in any game is a whole other story, they could add an ear damage effect into survival though
