Green noise
Updated 22 October 2026
Green noise is noise centered in the middle of the hearing range, with the very low and very high ends softened. It is often described as the sound of nature, like wind in leaves or a distant stream. People use it when white noise feels too bright and brown noise feels too heavy.

What green noise is
Unlike white, pink, and brown noise, green noise has no strict technical definition. Sound apps use the name for noise with a bump in the middle, around 250 to 1,000 Hz here. The idea is that natural ambient sound, measured over a day, tends to center in that range. It is a friendly name more than a scientific one.
Green noise for sleep
People who find brown noise boomy often settle on green noise for sleep. It covers voices and household sounds well and feels gentler than white noise.
