One of the common arguments in audio circles is how much resolution we need for audio samples. The number of bits determines the dynamic range. So if we determine the dynamic range, we can work backward and arrive at the equiv. bits of resolution. Folks then quickly pull out their SPL meter, show pretty high meter readings of noise floor in recording/listening space, and declare that the required dynamic range is very low, much lower than even 16 bits requires. Therefore, even CD is a waste let alone high-resolution formats! At face value this seems rather valid. But when you dig deep, really deep, the story unravels as I told in Widescreen Review magazine article a few months ago. Since some time has past since its publication, I have gone ahead and put a copy online: Understanding True Room Dynamic Range: http://www.madronadigital.com/Library/RoomDynamicRange.html
The article also starts us on the path of understanding psychoacoustics, i.e. the science of how we hear, as applied to unusual situations such as room acoustics (the common place is in audio compression such as MP3/AAC).
Enjoy and as always, appreciate feedback/correction, etc.
