Thank you VERY much. This is very interesting; I'm off to go try it.

If you happen to know, does your understanding about background noise suggest that using a white noise generator of some kind is ineffective at combating a "quiet room?" I've been going between nature sounds and pink noise in such an environment. It'd be convenient if that were sufficient, but I'd much like to know if I can squeeze out some extra efficiency by moving my study environment.

Thanks again, this was very well put together (as far as communicating the ideas goes), no fluff.
