About pink noise
Pink noise contains the same range of frequencies as white noise, but the treble is rolled back so the sound leans toward the lower and middle frequencies. Technically the power falls by 3 dB per octave; in practice it just sounds softer, fuller and less hissy.
Because that balance is close to how many natural sounds are shaped, people often describe pink noise as more “natural” than white — like steady rain or wind through trees. This pink noise generator plays it straight from your browser and loops it seamlessly, with a brightness control to tilt it warmer or brighter and a sleep timer to fade it out on its own.
It’s a popular, gentler alternative to white noise for relaxation and for sleep, and audio hobbyists also use it as an even reference for getting a feel for how a pair of speakers or a room sounds. Everything runs on your device with nothing to install, so you can leave it playing for as long as you like. As always, whether it helps is personal — set the volume low and adjust to taste. For an even deeper sound try brown noise; for a brighter one, white noise.
Pink noise FAQ
What is pink noise?
Pink noise contains all audible frequencies, but the higher ones are quieter than in white noise — the energy drops by 3 dB per octave. That gives it a softer, deeper, more balanced character that many people find easier on the ears.
What does pink noise sound like?
It is often compared to steady rainfall, wind through trees, or a gentle waterfall — fuller and less “hissy” than white noise, but not as deep as brown noise.
What do people use pink noise for?
It is commonly used as a calmer alternative to white noise for sleep and relaxation, and by audio engineers to check the tonal balance of speakers and rooms. Whether it helps you personally is worth testing yourself.
Is it free?
Yes — free, no sign-up, nothing to install. It generates the sound in your browser and loops continuously, with an optional sleep timer.
