What it sounds like
Green noise is a gentle rush centered on the middle frequencies, like a breeze moving through trees or the soft wash of a stream heard from a path. The lows and the highs are both turned down, so what remains is the part of the sound where speech and much of nature sit. It feels mellow, round and a little hollow, and it has none of the bass of brown noise or the sparkle of white. There is no beat or pitch, and the sound stays level for as long as it plays.
When it helps
People who find white noise too bright and brown noise too heavy sometimes settle on green, since it is easy on the ear and feels natural. It suits a calm evening, quiet reading and focused work, where a soft, mid-range wash can stay in the background. It also pairs well with outdoor sounds such as leaves or a stream. If you want something to cover deep rumbles or high hiss, a wider color will do it better, because green has less to say at either end.
How it compares
Green noise is a convention, not a physics definition. White, pink and brown are defined by how energy slopes across the frequencies, and engineers use them for testing. Green has no standard definition, so what you hear under that name depends on the maker. In NoiseZ it is shaped to center on the mid frequencies. Pink noise covers the whole range with a gentle slope, white leans bright and brown leans deep. Green sits in the middle of that picture, narrower than any of them, and has a softer, more natural feel because most of its energy is in the middle.
