I have the same problem, so I've had to do things to cope with it. Fortunately, I have an office with a door at my work now, and that helps tremendously. At home I have a room to work in where I can shut the door and not hear the TV. When I need to concentrate, I shut down the Twitter, E-mail, and IM clients, and any other things on my computer that might be distracting. I only run programs related to the task at hand.

I have also found that a daily time of quiet prayer and meditation is helpful. If you don't believe in prayer, some other kind of meditation will probably help, too. Lately I've been incorporating MP3s from pray-as-you-go.org, which are very well done short sessions of Ignatian guided meditation incorporating beautiful music.
