SUMMARY

White noise is characterized by a flat frequency spectrum, providing a consistent sound across all audible frequencies. In contrast, black noise is defined as the absence of sound, akin to silence. The discussion highlights the confusion surrounding the term "black noise," with some participants equating it to silence rather than a specific type of noise. Resources such as Wikipedia provide additional context on the various colors of noise, including white and pink noise.

PREREQUISITES
  • Understanding of sound frequency and spectrum
  • Familiarity with audio engineering terminology
  • Basic knowledge of noise types (white, pink, black)
  • Ability to research audio concepts online
NEXT STEPS
  • Research the characteristics of pink noise and its applications
  • Explore the effects of white noise on sleep and concentration
  • Investigate audio filtering techniques that affect noise color
  • Learn about the psychological impacts of different noise types
USEFUL FOR

Audio engineers, sound designers, psychologists studying sound effects, and anyone interested in the science of noise and its applications in various fields.

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:

http://en.wikipedia.org/wiki/Colors_of_noise
 
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.
 
Okay, this thread is deteriorating, and old. Thread locked.
