I have been a developer for a little more than a month now and what I have discovered is that although the office is open, whenever someone passes you, they treat you like you are in some kind of a no-distraction bubble, even if you get along really well. I have become to respect that culture.
I work in an open office and while I don't get too many interruptions with people coming up and distracting me, the office tends to be very noisy on times and it does interfere with concentration.
I've seen suggestions for good noise cancelling headphones but I don't feel very comfortable wearing headphones for long periods of time.
