GUIDE · CHOOSING SOUNDS
White noise, pink noise, nature sounds or lullabies? How to choose
Open any sleep app and you'll see a long list: white noise, fan, rain, ocean, music box. They fall into a few groups, and each suits a different situation. Once you know the difference, you won't need to audition a new track every night.
Four kinds of sound
| Type | Sounds like | Character | Good for |
|---|---|---|---|
| White noise | TV static, hair dryer | Even across frequencies, strongest masking | Blocking household noise |
| Pink and brown noise | Fan, waterfall, low rumble | More low frequencies, softer to the ear | When white noise feels harsh |
| Nature sounds | Rain, river, ocean, wind | Steady with gentle variation | Daytime naps, a more natural feel |
| Lullabies and music box | Soft melodies | Melodic, weaker masking | Bedtime routine, calming down |
Choose by the problem you're solving
- Baby wakes from household noise: pick a steady, melody-free sound like white noise or a fan.
- White noise sounds too sharp: switch to rain, a waterfall or a deeper noise.
- Baby needs calming before sleep: play a lullaby first, then switch to a steady sound or let the timer end.
- Daytime naps in a brighter room: nature sounds feel less out of place.
Once you find it, stick with it
When you find a sound your baby settles to, use the same one consistently so it becomes a sleep cue. Switching every night makes that connection harder to form.

FAQ
Is pink noise better than white noise?
Neither is universally better. Pink noise has more low frequencies and many people find it softer, while white noise masks other sounds more strongly. Go by how your baby and you respond.
Can I play songs with lyrics?
During the routine, sure. For falling asleep, steady sounds without words are less likely to grab your baby's attention.
How long should it play?
A 30 to 60 minute timer is enough in most cases, so your baby falls asleep to steady sound and it stops once they're settled.
