Pink noise for sleep
Pink noise sits between white and brown: its power drops gently as the pitch rises, which is the same balance you hear in steady rainfall, wind through trees, or a flowing river. To our ears it sounds natural and even. Press play to listen.

Why pink noise sounds so natural
Most calming sounds in nature follow a '1/f' balance — quieter highs, fuller lows — and pink noise matches it almost exactly. That's why it feels smoother and less harsh than white noise while staying brighter and airier than brown noise.
Pink noise and deep sleep
Pink noise is the most-studied colour of noise for sleep: small studies have linked steady pink noise to more slow-wave (deep) sleep and even better next-day memory in some groups. The research is early, but the calming, even texture makes it an easy, pleasant thing to try tonight.
Continuous pink noise plus a timer
Mynded generates pink noise live so it never loops, and lets you set the volume and a fade-out sleep timer. Blend it with rain or ocean in the app if you'd like a richer, more layered soundscape.
Mix it, time it, sleep to it
In the Mynded app you can layer soundscapes, set a fade-out sleep timer, and add AI sleep stories and guided wind-downs — all shaped around how you feel tonight.

What does pink noise sound like?
Like steady, even rainfall or a soft waterfall — fuller than white noise but not as deep as brown noise. Most people find it the most natural-sounding of the three.
Does pink noise actually improve sleep?
Some small studies link it to more deep sleep and better memory consolidation. Results vary, but it's a safe, free thing to try if you're a light sleeper.
Can I play pink noise all night?
Yes, at a comfortable volume. Or set a sleep timer in Mynded so it fades out after you've fallen asleep.
