But it turns out many of us are using white noise as a catch-all phrase.
Background noise that blocks other sound can actually be broken down into a variety of colors.
And knowing the difference between the different noise colorsmay help you sleep better.
The differences in the colors come down to frequency and amplitude.
True white noise isn’t just any background noise.
Then there’s pink noise.
Think calm ocean waves or agentle rain.
Pink noise has even been shown to improve memory (fromSound of Sleep).
The opposite of pink and brownian noises are blue and violet.
