White noise for sleep
White noise is a steady, even sound that holds equal energy across every frequency your ear can hear — the soft 'shhh' of an untuned radio or a fan. Press play to start it instantly, right here in your browser.

Why white noise helps you sleep
Your brain doesn't react to constant sound — it reacts to change. White noise raises the background 'noise floor' so a slammed door, a creak, or passing traffic no longer stands out sharply enough to wake you. That makes it a favourite for light sleepers, shift workers sleeping by day, and noisy apartments.
White noise for babies and focus
The same masking effect soothes crying babies (it loosely resembles the whoosh they heard in the womb) and helps people concentrate in open offices by smoothing out distracting chatter. It can also take the edge off tinnitus by giving the ears something neutral to settle on.
Endless playback with a sleep timer
Mynded synthesises white noise in real time, so there's no short loop repeating every few seconds and no track to buy. In the app you can layer it with rain or ocean, adjust the volume, and set a sleep timer that fades it out after 15 to 60 minutes so nothing wakes you later.
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.

Is it safe to play white noise all night?
Yes, at a comfortable, moderate volume — roughly the level of a soft shower from across the room. Keep speakers an arm's length away and avoid high volumes, especially for babies.
What's the difference between white, pink, and brown noise?
White noise has equal energy at every frequency (brighter, hissier). Pink noise rolls off the highs for a balanced, rainfall-like sound. Brown noise rolls them off further for a deep, rumbling tone.
Do I need headphones?
No. White noise works through speakers or headphones — whatever is comfortable for sleep. A bedside speaker is usually easier than wearing headphones overnight.
