Baby sleep sounds
For nine months, your baby fell asleep to a constant whoosh — blood flow, heartbeat, muffled voices — louder than a vacuum cleaner. Silence is what's unfamiliar. A steady, womb-like sound helps newborns settle, soothes crying, and masks household noise during naps. Press play to try it.

Why white noise soothes babies
The womb is a noisy place, so newborns often calm faster with a steady whoosh than in a silent room — it recreates what they know. The sound also masks the sudden noises (doorbells, older siblings, dishes) that end naps early, helping babies settle faster and stay asleep longer.
Keeping the volume safe
Keep it at a moderate level — about as loud as a soft shower heard from across the room — and place the speaker well away from the crib, not inside or beside it. The goal is a gentle background layer, not volume. When in doubt, quieter and further away is better.
A settle-down cue that travels
Played consistently at naps and bedtime, the sound becomes a cue your baby associates with sleep — useful at home and even more useful at grandma's or in a hotel. Mynded generates it live with no looping seam, and the sleep timer can fade it out once your baby is deeply asleep.
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 white noise safe for newborns?
At a moderate volume with the speaker placed well away from the crib, yes — it's widely used to settle newborns. Avoid high volumes and don't put the source right next to your baby's head.
Should the sound play all night or just to fall asleep?
Both approaches work. All-night play masks noise through every sleep cycle; a fade-out timer is gentler if you'd rather your baby not depend on it. Try each and follow your baby's lead.
Will my baby become dependent on white noise?
It's a sleep cue like a dark room or a bedtime routine — helpful, and gently weanable later by lowering the volume night by night once sleep is established.
