I have the opposite yet same reaction to open office environments. I was always the loud person in the group, and I have a hard time staying out of conversations with others. I try to keep myself to myself, but I know that I distract others around me. Ironically, having a private office not only kept my noise from other people, but I actually got quieter because it was simply the presence of the group around me that got me loud. I got a lot more work done too, since I wasn't constantly distracted from the discussions going on around me, work related or not.
