Green noise

What green noise sounds like

Green noise is a mellow, rounded sound, like wind moving through trees or a river heard from far away. It is strongest in the middle of the range, around 500 Hz, with softer lows and highs. It has less rumble than brown noise and less hiss than white.

There is no single standard for green noise, and apps make it in different ways. Umber starts from pink noise and brings the middle pitches forward, then mixes a little plain pink noise back in. That keeps it full and natural, so it never sounds like a thin tone.

How it differs from the other colors

Brown, pink and white noise are defined by how the sound changes from low pitch to high pitch. Green noise is about one band in the middle. If brown feels too boomy and white too bright, green sits between them and is worth a try.

When people use it

A lot of everyday sound in a home sits in the middle range: voices through a wall, a TV in the next room, dishes, footsteps. Green noise puts its energy right there, so it can cover those sounds without being loud. People use it as a soft background for focused work, or at night when they want something softer than white noise.
