    I have never seen the term "black noise". White noise is noise where the frequency spectrum is flat. Colored noise has a non-flat spectrum due to the characteristics of the source or some filtering.

    Superficially, I would assume that black noise would be complete absence of noise... considering how I really don't know alot about it. kinda like black is the absence of light or color.
