I'm surprised you're still sane. Noisy people drive me crazy. A former colleague of mine did everything loudly. She got on my nerves so much. I found out after she retired that my colleagues had also found her behaviour oppressive. I think being loud is aggressive behaviour and imposes on other people's personal and mental space.

As for sniffing and stuff, that drives me nuts too. I'm a librarian and the students in our reading room are constantly sniffing and snorting. We had a student once who constantly chewed gum and kept on making cracking sounds with it. I jumped every time. When she wanted help, I muttered something about not being able to think when she chewed gum at me and that kept her quiet for a little bit.

So, lots of sympathy and enjoy your new space.
