Green Noise

Green noise concentrates energy in the mid-frequency range (around 500 Hz) — roughly where most environmental ambience sits. It sounds less harsh than white and less bass-heavy than brown, which is why some listeners find it the most 'natural' of the synthetic noises.

What you're listening to

A balanced, mid-range noise color with a soft rolled-off top end and less bass than brown. Comparable to a gentle waterfall recorded from a short distance, without the pitched elements of water itself.

Why it works

Green noise's mid-range concentration matches the frequency profile of most outdoor ambient sound. For listeners who find white noise too sharp and brown too muffled, green often lands well. There isn't specific research on green noise vs. other colors — it's mostly a preference question.

Best for

  • general masking
  • daytime focus with ambient feel
  • when white and brown both feel 'off'
