Best noise colors for babies

The gentler, fuller colors work best for infants:

  • White noise — most closely resembles the womb's whoosh; the classic choice.
  • Pink noise — softer than white, balanced and natural.
  • Brown noise — deep and gentle, echoing low womb sounds.

Baby safety: volume and distance

This matters more than the color. Keep any infant sound machine below about 50 decibels and place it well away from the crib — at least 2 metres (7 feet). Never put the device in or on the crib, and turn it down as low as still works.

  • Keep volume around 50 dB or lower.
  • Place the speaker at least 2 metres from the baby.
  • Never place a phone or speaker inside the crib.
  • Use a timer or switch it off once your baby is asleep.

Frequently asked questions

What is the best noise for baby sleep?

White noise is the classic choice because it resembles the womb, but pink and brown noise are gentler alternatives that also soothe many babies. Whichever you choose, keep the volume low and the speaker well away from the crib.

Is white noise safe for babies?

Yes, when used correctly: keep it below about 50 decibels and at least 2 metres from the crib, and avoid long periods at high volume. See our white noise for babies guide for full safety details.
