Green Noise Generator
Green noise is the “middle” of the noise spectrum — centered around 500 Hz, it sounds like steady rainfall or a distant waterfall, which is why so many people find it easier to sleep to than the hiss of white noise.
Press play, set the 8-hour timer, and let it run all night. Brown, pink and white noise are one tap away if your ears prefer a different color.

Frequently asked questions
What is green noise?
Noise energy concentrated in the middle of the audible spectrum (around 500 Hz). It resembles the sound of steady rain or ocean surf — softer than white noise, brighter than brown.
Is green noise good for sleep?
Many sleepers find it masks disturbances (traffic, snoring, tinnitus) with a more natural feel than white noise. Keep the volume low and steady — masking works at gentle levels.
Green vs brown vs pink noise?
Brown is deepest (rumble, like a waterfall up close), pink is balanced, green sits mid-spectrum like rainfall, white is brightest. There’s no wrong answer — use whichever your ears relax into.
