What is Green Noise & Why Consider a Green Noise Sleep Machine?

Green noise is a type of noise that contains a wide range of frequencies like other “color noises” including brown noise, pink noise, and white noise. Unlike other color noises, green noise emphasizes lower frequencies. Not to get too technical, but this makes it ideal for promoting the production of delta brain waves, which are associated with deep sleep and relaxation. Cool, right? The sound emitted by green sound machines also may help regulate the autonomic nervous system, making it helpful for people who suffer from anxiety.

What Does a Green Noise Machine for Sleep Sound Like?

Think of nature: green noise reminds most people of natural sounds like the rustling of leaves or the gentle whir of distant traffic.

How do Green Noise vs White Noise vs Brown Noise Compare?

Have you ever fallen asleep to the sound of cresting waves on the beach? There may be a reason for that, according to science, and it’s related to green noise. All color noises contain all frequencies of noise audible to the human ear. It’s the ratio of those frequencies that creates different “colors” of noises, like white noise, brown noise, pink noise, and green noise. White noise contains all frequencies in equal proportion. Green noise contains a higher proportion of mid-tones, making it sound more “rounded” like the cresting of a wave as it breaks on the shore and less like the “hissing” that you might associate with white noise. Both brown noise and pink noise, meanwhile, boost lower frequencies.
