Green Noise Player

Updated 27 June 2026

Green noise is a mid-frequency noise centred roughly around 500 Hz — the part of the spectrum where many natural background sounds live, like a distant stream or a calm forest. This free player loops soothing green noise without the brightness of white noise.

What does green noise sound like?

Green noise sounds like the steady ambience of the natural world — a faraway stream, soft surf or wind through trees. It emphasises the middle frequencies and rolls off the harsh highs, so it feels calmer and more organic than white noise.

What is green noise good for?

Green noise is mainly used for sleep, relaxation and meditation. Its nature-like, mid-range tone is gentle and non-distracting. As the Sleep Foundation notes, evidence for green noise specifically is limited, but background noise can still help mask a disruptive environment.

White vs pink vs brown noise

Noise	What it sounds like	Best for
White noise	Bright, even hiss across every frequency	Masking sudden sounds; offices; babies
Pink noise	Soft and balanced, like steady rain	Relaxing and deeper sleep
Brown noise	Deep, warm rumble with the highs rolled off	Sleep, focus, low-rumble masking

Frequently asked questions

What is the difference between green and white noise?

White noise spreads energy evenly across all frequencies and sounds bright and hissy. Green noise concentrates energy in the middle frequencies, so it sounds more like calm nature and is often perceived as more relaxing.

Is green noise good for sleep?

Many people find its nature-like, mid-range sound calming for sleep. There is limited direct research on green noise, so treat it as a soothing background rather than a proven sleep treatment.

Does green noise loop seamlessly?

Yes — it streams as a lossless, gapless loop that plays continuously with no break.
