heavy music can have the same effect. (as an aside; if I have to concentrate hard silence tends to distract me, I will get up and make noise to stop it being silent :) so I had to develop these technigues).

I dont have a study to back that up :) but I know Im not alone in experiencing this (and I think it actually backs up what your saying too).
