Green Noise
Green noise sits in the middle: a soft outdoor-ish wash, with less hiss than white noise and less boom than brown. Press play and the free green noise generator starts here in the browser, with no signup and no download. People pick it when they want something nature-like in the room without listening to actual rain. It is a poor match if you need to cover bass through the floor.
Ready to play
Put this under rain or a fire, keep the blend you end up with, and play it through the night with your screen off. The Slo app does that on iOS, Android and Mac.
What green noise sounds like
It sounds like distant water or leafy wind, without being either. Use it when white noise is too sharp and brown noise is too heavy, and the job is a quiet desk, journaling, or winding down. It won't cover a truck, a boiler, or a neighbor's subwoofer, because those need the deep rumble of brown noise.
The name is informal, so different pages called green won't match each other, and a single tone at some advertised number is not noise at all. It is a listening preference rather than a wellness frequency, and it treats nothing.
When the middle is enough, and when it is not
For desk work it can take the edge off bits of speech without the hiss of white or blue noise, though it can't block a loud conversation through a wall. Try it on one real task and notice whether you start listening to it. If you do, it is too loud or it is the wrong sound for the room.
At night some people like how outdoor it feels. Others find it nasal on a phone speaker, because a small speaker turns those middle pitches boxy. Pink noise or an actual rain recording usually sounds more natural on one of those.
Volume, speakers, and layers
Start low. Green noise sits around the pitch of voices, where ears are most sensitive, so it gets loud faster than the slider suggests. Put the speaker a few feet away, and use the 15, 30, or 60 minute timer if you only want help settling. Don't crank it to compete with the room.
The generator is free and runs in any browser, with no account and no app to install first. For a bit of space, open the online mixer and put river water quieter on top. The guide to the benefits of nature sounds is honest about how a real recording differs from a color. Alternate both if you are deciding whether you want texture you recognize or texture that stays anonymous.
Presets built on green noise
Each one opens with the volumes and the timer already set for a single job, so you can press play and leave it alone.

Frequently asked questions
Is green noise the sound of nature?
No. It can remind you of distant water or wind, but a nature recording has identifiable events in it and this does not.
What frequency is green noise?
There is no official number. Green noise is a broad, soft wash rather than a single tone, whatever the pages advertising one tone say.
Is green noise lower than brown noise?
Usually the opposite. Brown noise is the deep rumble, and green sits higher and lighter, which is why it fails against bass through the floor.
Can green noise help me relax?
Some people find the even, moderate character easy to sit with. That is personal, not a guaranteed effect. Keep it quiet and treat it as a routine, not a treatment.
