Hi all I want me to explain what white and black noise is .And what's the difference betwween them?
 
Physics news on Phys.org
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.

Good old google. I googled "white noise" "pink noise" "black noise" and got lots of hits. Here's one of the first ones, from the wikipedia:

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

it's SILENCE!:!)
 
I had a link that refferred to white and black noise as Country Western and Rap, but I can't find that link anymore.
