Green Noise
Green noise concentrates its energy in the middle of the spectrum — roughly the band of rushing water or rain on leaves. Softer than white noise and brighter than brown, it's the noise color that took off as a sleep aid. Soundlull generates it live in your browser.
The noise colors (white, pink, brown, green & gray) generate real audio in your browser. Loop-based channels play once their audio files are added.
Frequently asked questions
What is green noise?
Green noise is noise with its energy concentrated in the middle frequencies — around the band of rushing water, wind through leaves, or steady rain. It's softer than white noise and brighter than brown, which is why many people find it the most natural-sounding color for sleep.
Green noise or brown noise — which is better for sleep?
Both are gentler than white noise; the difference is depth. Brown noise is a low, bass-heavy rumble, while green noise sits in the mids and sounds more like natural moving water. Brown tends to suit people who want a deep blanket of sound, green those who want something lighter and more organic. Try each — or layer green noise over a little brown.
What's the difference between white, pink, brown, green, and gray noise?
They differ in how energy is spread across frequencies. White noise is flat and bright, pink is balanced and natural, brown is deep and bass-heavy, green concentrates on the mids like rushing water, and gray is shaped so every pitch sounds equally loud. Try each and use whichever you find most comfortable.
