Relaxing before sleep
A steady sound bed can be appealing to people who find white noise too bright. Pink noise is not a medical treatment or a guaranteed way to sleep better.

Listen: Pink Noise vs Brown vs White
Switch between three distinct recordings using one persistent player. The active audio changes without navigating away, while the existing sleep-timer deadline stays in place.
Pink NoiseBalanced lower and middle frequencies, gentler hissPower spectral density ∝ 1/f
Brown NoiseMore weight in the bass, less in the treblePower spectral density ∝ 1/f²
White NoiseBrighter and more even across frequencyApproximately constant power per Hz
These source masters have different integrated digital loudness: Pink -23.6 LUFS, Brown -27.8 LUFS and White -22.3 LUFS. The same volume setting will not produce equal perceived loudness. Start low when switching.

The acoustic character of Pink Noise
Pink Noise is often described as equal energy per octave. Its idealized power spectral density falls approximately as 1/f, equivalent to a decline of around 3 dB per octave, or 10 dB per tenfold frequency increase. That is why it typically sounds less sharp than White Noise but not as dark as Brown Noise.
Every speaker and headphone has its own frequency response. Listening on a phone may make the lower frequencies less prominent, so you should compare at a comfortable level rather than compensating with high volume.
When people listen to Pink Noise
Reading and deep work
Pink noise provides a relatively smooth background without voices or a changing scene. Whether it helps or distracts you depends on personal preference and the task.
Focus listening optionsBackground noise masking
It may make some intermittent environmental sounds less noticeable by adding a stable background. It cannot remove external sounds or replace ear protection.
Masking collectionHow this Pink Noise master was made
WhiteNoiseChoir created an independent full-length synthetic noise master using a frequency-domain colored-noise process. The file is not a short repeated excerpt, rain recording or third-party audio. It contains ten minutes of generated audio; continuous playback repeats the complete master.

The 10-minute MP3 is not a ten-minute session limit. Where supported, native HLS runs multiple cycles without needing a JavaScript restart after minute ten; elsewhere the MP3 loops. Hardware or operating-system interruptions can still stop playback. Use the loop test to check the source boundary. LUFS is a digital-file level, not a safe sound-pressure reading at your ears.
Pink Noise — Frequently asked questions
Is Pink Noise quieter than White Noise?
Not necessarily. Pink Noise emphasizes less high-frequency energy, so it may sound softer or less hiss-like, but the actual loudness depends on the master level, playback device and volume. The files are not automatically loudness-matched.
What is meant by equal energy per octave?
In the idealized model, each frequency band spanning a doubling of frequency carries approximately the same power. It does not mean each individual hertz is equally strong; that describes White Noise.
Does Pink Noise help with sleep or focus?
Some listeners enjoy it while winding down or working, but personal responses vary. Do not interpret audio preferences as proven treatment for insomnia, concentration disorders or other medical conditions.
Does this recording contain voices, music or nature sounds?
No. The main Pink Noise master is synthesized noise, not a recording of weather, speech, or music. Distinct rain and fan recordings are in other library categories.
Will the sound stop at minute ten?
No. Ten minutes describes the independent master file. Continuous listening repeats that source until you stop, the timer runs out, or the device interrupts playback.
