Pink Noise is Best Noise

The right noise will help you rest.

Sleep's an important function of life, so why not treat it that way? Pink noise can help you sleep, even better than white noise, and which of our air purifiers are pink noise generators.

What exactly is white noise? Pink noise?

“White” noise is created by combining many high and low frequencies together. It is similar to the sound of TV static.

“Pink” noise is less random noise that has "equal power per octave". Basically, the low frequencies in pink noise overpower the high ones, according to

Pink noise is sometimes compared to your heartbeat. It's more steady and goes at an equal pace. Pink noise is the most common noise found in nature.

Why is it called pink and white noise?

Pink and white noise are named after the color spectrum. Just like the color white is made up of multiple colors, white noise is a blend of multiple frequencies that form one unique sound.

Similarly, shades of red are found in the lower end of the color spectrum, which is where the term "pink" noise came from.

Pink noise is better than white noise.

So, why is pink noise better?

White noise is used to cover other sounds by essentially overwhelming them. For example, if you are in a house with a lot of people who are making too much noise, you might turn on a machine, such as a fan, to block out the outside noise.

On the other hand, pink noise blends into the background and provides a steady tempo to sleep to. In fact, one study found that participants slept up to 25 percent better with pink noise than white noise. Pink noise doesn't simply cover other noises, so much as masking them, bringing down the impact of noises that might otherwise disrupt normal sleep.
