I’m not ignorant and I do like talking to you, honest. But getting into the flow takes time and noise interrupts in. Music in the background has always seemed to help block out the annoying thing. Its why in the early morning or late evening, so much more work is done. Sure you know yourself, you may be in work from 9-6, but you really only get about 2 hours of good work done. And now here is why.

http://softwarenation.blogspot.com/2009/01/importance-of.html provided a pretty good but basic enough explanation of the brain and how it works in sections. Combine this with what I knew previously, and it makes a lot of sense.

While programming part A, the voice in your head part,  is running away with itself, swapping variables and the like, part B, the thinking part, is looking ahead and coming up with that creative code block you are about to write. Part C, the hearing part, is being kept nice and busy by the music coming in stopping other noise coming in and ending up in the thinking part. Because when it gets to the thinking part, it is like a big freight train hitting a mountain, it derails and looses all its cargo. You start down the hill on another track, what it was you heard and the further you go, the more you’ve left behind. And just like that big freight train, it takes a long time to get back up to speed on the hill, and you have to pick up all those information bits that you lost before.
