Pink noise

Balanced across the spectrum, and close to the sound of steady rain.

The middle option

Pink noise spreads its energy evenly across octaves rather than across frequencies, which is roughly how human hearing is organised. The result sits between the other two: fuller than white noise, brighter than brown, and closest of the three to a natural sound — most people say steady rain or wind through trees.

That balance makes it a good default if brown noise feels muffling and white noise feels sharp. It covers a reasonable amount of speech while still being comfortable to leave on for hours.

Like the other noise channels, this is synthesised as it plays, so it never repeats, uses no data and can run indefinitely. It is CC0, so you can use it for anything.

If you like pink noise because it sounds like rain, the rain channel gives you the real texture — drops and all — synthesised the same way.

Questions

  • How is pink noise different from white noise?

    White noise has equal energy at every frequency, so it sounds bright and hissy. Pink noise drops by 3 dB per octave as it rises, so it sounds fuller and softer while still covering a wide range.

  • Is pink noise good for studying?

    It is a reasonable compromise: enough coverage to mask a room, without the fatigue that bright noise can cause over a long session.
