Rene --

What you say about shaping to other distributions is true, of course. But I 
wonder if there isn't a further reason. If the distribution is not in some 
sense equalized (white, pink, I don't care), then certain frequencies or 
frequency bands will be emphasized. I think this would give an audible 
characteristic coloration to the sound. It seems to me this would be 
undesirable, just like coloration in a loudspeaker system.

It would be interesting to know more about physiological response to 
various kinds of distributed-frequency sounds.
