PlayWhich sleep sound is right for you?
The "colours" of noise differ in how their energy is spread across pitch. White noise is even and bright and masks sudden sounds well. Pink noise softens the highs for a natural, rainfall-like balance linked to deeper sleep. Brown noise goes deeper still — a warm, low rumble many find the most soothing. Nature sounds like rain, ocean, and thunderstorms add gentle rhythm, while fan noise recreates a familiar bedroom favourite and binaural beats use two tones to create a slow, sleep-tuned pulse.
Why these don't loop
Most sleep-sound tracks are short clips stitched into a loop, and once you notice the seam it's hard to ignore. Mynded synthesises every sound in real time, so it stays seamless all night — and in the app a sleep timer fades it out gently after 15 to 60 minutes so nothing wakes you later.
