music and audio dance and electronic musicWhat does white sound mean?
In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density. White noise refers to a statistical model for signals and signal sources, rather than to any specific signal.
Considering this, what does white noise do to you?
White noise creates a masking effect, blocking out those sudden changes that frustrate light sleepers, or people trying to fall asleep. "The simple version is that hearing still works while you're asleep," says Seth S. Horowitz, a neuroscientist and author of The Universal Sense: How Hearing Shapes the Mind.
Keeping this in consideration, what is an example of white noise?
Streams, the wind in the tress, rain, vehicles, machinery, footsteps on gravel or leaves, fire and even sounds heard by babies in the womb are a few examples of noise in our environment. I bet you can think of more examples.
Our white rain sound recording is totally natural: no synthetic white noise has been superimposed here. Yet, it sounds close to white noise. Not all rain sounds are white though, mostly because of the environment in which the rain falls alters the color of the sound too.
