What Is Green Noise? Understanding the Colors of Sound
August 01, 2023

You’ve probably heard of white noise — it’s usually a static-like or high-pitched sound you might like to have in the background while you work to drown out other noises. But you might not know that colored noise doesn’t end there. There’s a whole rainbow of sound, including green noise.

Green noise has been getting some attention on social media lately, especially on TikTok. Many users are highlighting its effectiveness as a sleep aid. Let’s look into the different colors of noise to better understand green noise and how it can help.

The Different Colors of Noise

In audio engineering, sounds are categorized into different colors based on each noise signal’s power spectrum density. This measurement depends on the size of the wave and its frequency, which is the speed of its vibration per second. The signals sound different when perceived through human ears and appear with different textures when viewed through images. That’s why each noise signal has its own identifying color.

Each colored noise has unique properties. Some can even be used for therapeutic purposes, such as promoting sleep or relaxation. The different types of sound by color include:

  • White noise
  • Pink noise
  • Brown noise
  • Blue noise
  • Violet noise
  • Gray noise
  • Green noise

What Is Green Noise?

Green noise is a type of sound that features a wide range of frequencies, making it similar to white noise in some ways. While both colors of noise have an even distribution of energy across the spectrum, green noise focuses on middle to lower frequencies that produce sounds resembling nature. Green noise might sound like running water or wind through trees. These sounds can evoke a soothing feeling similar to what you experience when walking through quiet outdoor scenery.

The unique sound profile of green noise creates a calming effect that can help people who have difficulty falling asleep. Green noise effectively drowns out unwanted sounds. It can also reduce the perception of the ringing and buzzing sounds that those with tinnitus experience.
