Hi Mark Mills --

I'm not at all sure that is true. Well, to a computer scientist or to an
information scientist, yes, 'noise' is irrelevant background and
non-analyzable.
But to an acoustic scientist, no, noise is quite simply the sound-
"The sensation caused by vibrating wave motion that is perceived by the
organs of hearing."
There are special cases of noise, called 'pink noise' and 'white noise'
that are indeed fully random (to the extent they can be) and patternless,
since they are full or near full-spectrum sounds without repeating
characteristics.
