How loud should baby white noise be?

Pediatric guidance generally recommends keeping infant sleep sounds at or below ~50 dB at the baby's ear, comparable to a soft shower. Use a phone sound meter to verify, and keep the speaker at least 1–2 meters away.

Will it keep playing if my phone screen turns off?

Yes, on most modern phones and tablets — but some browsers pause background audio. If playback stops, leave the tab visible or use a tablet dedicated to the soundscape.

Why this mix works

In the womb a baby hears a constant low rumble — the mother's heartbeat, blood flow, and digestive sounds — at around 70–90 dB. White noise paired with slow ocean waves mimics that environment, which is why so many newborns settle quickly to a steady sound bed. This preset is calibrated to be loud enough to mask household noises without being uncomfortable at close range.

Helps newborns settle and stay asleep through nap transitions.
Masks doorbells, dogs, and older siblings without startling the baby.
No ads, no autoplaying videos — safe to leave running on a parent's phone.
