I wish I had an answer for you. To ease distraction you might want to try "brown noise." I use my mynoise.net (I'm not affiliated- I probably found it in a thread here on HN.) I also have some "nature" mp3s like ocean waves crashing and rainfall and such. It's remarkable how well it gets me in "the zone."

One word of caution: don't turn up the volume to drown out the background noise. You only need to be able to hear the brown noise, not overwhelm everything else. I did that and my hearing was off for a day and a half. I think that because the sound energy is distributed more evenly throughout the spectrum you're getting more intensity on your eardrum than you think.
