I know what you mean being newer myself. I agree with TallPaul that identifying what you hear helps a lot. On my last camping trip I heard for the first time a red fox doing it's cool scream call sound. Since I already knew what it was I wasn't worried though. Like the others say I just think more exposure will help. I once early on took ear plugs which did a great job but I don't recommend. You can't hear anything even danger if you wanted and you only in able the fear instead of trying to get use to it.
