I work in a quiet office, with the exception of when I need to go out to the hangars, and while it's not my preference, I've found ways to deal with it. If you can wear earbuds, try out listening to audio books. I get away with it because I only put one earbud in, which allows me to still hear what's going on around me. I also try to stand up and walk around for 5 minutes or so once an hour. Just to break the monotony that can sometimes set in. A lot of people around me eat the lunch at their desk, but I'd go crazy if I did that. Even if it's just for 30 minutes, finding a different place to eat inside, or better yet, even outside (weather permitting), makes things much better.
Point is, eventually you'll find something that works and you'll slowly adapt over time. I definitely wouldn't leave without something lined up, but you might even find that once you adapt to your new work life, you enjoy certain things about it.
