MOTM

Multiple noise sources in a system can be useful. For one thing, two
noise sources feeding different audio chains sound different than one
feeding both. 

They are also useful as sources of randomness - if you need multiple
random sources at the same time, you need different seeds - without a
second noise source, I end up having to tie up a couple of high speed
cross modulating oscillators.

FWIW.
