Depends on who gets crammed together. A bunch of developers in a room are possibly going to be pretty considerate about noise.
I was in an 'open plan' office where there were four of us developers at a large desk with a sales guy at one end, a sales guy sitting at the other end of our desk, and another sales guy ten feet behind him at a desk.
We were generally pretty quiet, but the sales guys liked to shout across us all day. That is, when they weren't on loud phone calls.
