Green noise: free online generator
Green noise is a soft, mid-range sound that sits between deep brown noise and bright white noise. Many people say it sounds like a waterfall, steady rain or wind in the trees. Ours is generated live in your browser, so it never loops.

Press play and start at a low volume.
Use it for sleep, reading, work or covering a noisy room.
Add a little brown noise in the player if you want more depth.
Green noise has no strict scientific definition, unlike white or pink noise. Our version is pink noise with the deep rumble and the high hiss gently rolled off, leaving the middle of the range.
Green noise vs other noise colours
White noise: equal energy across every frequency. Bright and hissy, strong masking.
Pink noise: softer, more even to the ear. Close to steady rain.
Brown noise: deep and rumbly, like distant thunder or an aeroplane cabin.
Green noise: the middle of the range. Lighter than brown, gentler than white, and the closest to everyday nature sounds.
