Question

White noise:can anybody explain in simple terms what it means?

Answer 1

okay so bassically all white noise is, is all the noises of the noise spectrum. meaning its just a big noise snowball and it usually is heard on the tv or radio

Answer 2

white noise is noise at all frequencies.  most noise is made of subsets of different frequencies, and white noise is the broadband.

Answer 3

It is a random, non-repetitive sound wave. Its energy is spread out across the whole frequency spectrum, so it doesn't have a pitch. It sounds like hissing. The sound of a TV with no signal is white noise.

White noise has equal amplitude in all octave bands (amplitude = the distance the air molecules move, or size of the waves on an oscilloscope).
