What is green noise?
Green noise is a variant of the noise spectrum with its energy concentrated around the mid frequencies — roughly the 500 Hz region — rather than spread evenly (white) or weighted to the bass (brown). This is the band where the natural world's ambient sound tends to sit, which is why green noise is nicknamed nature's white noise.
Our engine generates green noise in real time by shaping full-spectrum noise around that natural mid-band, so it plays seamlessly for as long as you like.
Benefits of green noise
Green noise offers the masking power of the other colors with a sound many people find more pleasant and less fatiguing than a bright hiss or a heavy rumble. Because it evokes the outdoors, it can feel especially calming for winding down.
- Sleep: a soothing, natural backdrop that covers household and street noise.
- Relaxation & anxiety: the nature-like tone helps some people feel grounded and calm.
- Meditation: an even, non-distracting bed of sound for breathing practice.
- Tinnitus: mid-focused masking can help cover some kinds of ringing.
How to use the green noise player
Press play and set a comfortable, low volume. Try the Waves toggle to give the sound a slow, ocean-like swell, and use the Tone slider to fine-tune the balance. A Sleep Timer will fade the sound out gently after you fall asleep.
