Interesting article came out this week discussing new theories of Dyslexia that look at the role of distraction and attentional difficulties in high noise environments. You can find a very interesting overview of the recent batch of literature by CLICKING HERE. It's a short article and should definitely be read. I had a case just last week that this seems remarkably applicable towards.
I will track down the references for other articles it discusses and post them shortly for your information as well.
