Pink noise is the softer cousin of white noise. If white noise sounds like a hiss, pink noise sounds like a steady rain shower, which is why many parents find it easier to listen to through a long night. It’s a reasonable option to try, but it isn’t a magic upgrade: if you’re weighing the colors side by side, our pink vs white vs brown noise comparison covers the differences in one table.

This page is part of our guide to baby sleep sounds. Here’s what pink noise is, what the research really says, and how to use it safely.

What is pink noise?

Pink noise is a steady sound with more energy in the lower frequencies than the higher ones, so it sounds softer and deeper than white noise. Technically, every octave carries the same amount of energy, which our ears hear as balanced rather than bright.

You’ve heard pink noise many times without knowing it. Steady rain, wind in the trees and the distant rush of a river all have a similar character: even and constant, but without the sharp hiss of an untuned radio.

Still prefer an even deeper sound? Brown noise for babies is lower again, a soft rumble rather than a shower.

Is pink noise good for babies?

Pink noise can be a good, gentle choice for babies, as long as it’s played quietly and the device is well away from the crib. What it isn’t is proven to be better than other sounds.

So the honest answer is that we don’t know whether pink noise helps babies sleep any better than white noise. White noise has the most infant research, mainly a small newborn study (Spencer et al., 1990). Pink noise is best thought of as a softer-sounding version of the same idea: a steady background that masks household noise and becomes a familiar cue.

Pink noise vs white noise for babies: which should you choose?

Choose the sound your baby settles to at the lowest volume. That matters more than the color.

  • Try white noise first if your home is noisy or you need strong masking, for example a sibling up later or traffic outside. See our guide to white noise for babies.
  • Try pink noise if white noise sounds harsh to you, or your baby seems more unsettled than soothed by it.
  • Give it a few nights. A new sound is a new cue. Consistency is what turns it into a signal for sleep.

There’s no pink noise preview clip on this page yet. Gentle rain, above, has a very similar soft, even character.

How to use pink noise safely

The same rules apply to every noise color. Keep it at about 50 dB or lower at your baby’s ear, around the level of a quiet conversation, and place the device about 2 m (7 ft) from the crib. Pink noise may sound quieter than white noise at the same setting, so check the level rather than guess. Here’s how to check white noise volume with a phone.

Pink noise mixes to try

Pink noise blends well with nature sounds, because they share the same soft character. In Baby Mantra you can play up to three sounds at once and set each volume separately:

  1. Pink noise + rain on roof: a cozy, rainy-night feel. Keep the rain slightly louder than the noise.
  2. Pink noise + soft piano: music for the wind-down, then let the timer fade the piano while the noise carries on.
  3. Pink noise + womb sounds: a gentle mix for newborns.

Save a mix you like, then start it with one tap tomorrow. Set a timer from 15 minutes to 2 hours with a gentle fade-out, or play all night at a low volume with the screen dimmed. You can explore every feature of the Baby Mantra app.
