How loud should white noise be for a baby, and how far from the crib?
The general rule for baby white noise is quiet, far away and only as long as needed: roughly the level of a soft shower, with the phone or speaker across the room rather than in the crib, and a timer with a fade-out so it does not run loud all night. Every baby is different, so treat your pediatrician's advice as the final word.
Why quiet is the default
White noise is a background that masks sudden sounds: a door closing, a doorbell, an older sibling. It only needs to be a little louder than what it is covering, and there is no benefit in going beyond that. Babies' ears are small and can be sensitive to sound close by, which is why pediatric and parenting organizations generally advise keeping white noise quiet and away from the baby.
If two adults could talk comfortably next to the crib and the sound is not grating, you are usually in a sensible range. If it sounds loud to you, it is loud for the baby.
Setting the volume, step by step
Do this once before bedtime and you will not have to think about it every night.
- Start with the phone's media volume low, then fine-tune with the per-layer volume inside the app.
- Stand or sit where the baby's head will be and listen. Aim for about the level of a soft shower.
- Check that household noise outside the room is gently masked. If it is, stop there.
- If you layered several sounds, check the combined level again.
- If you want a number, measure at the baby's position with a sound meter app and ask your pediatrician what level they recommend.
Where to put the phone
Do not put the phone or speaker in the crib, next to the baby's head or on the crib rail. A dresser or shelf across the room, out of reach, works well. The farther away it is, the quieter the same volume is by the time it reaches the baby.
A charging phone can get warm, so place it on a hard, ventilated surface rather than on bedding or cushions, and keep the cable well away from the crib.
| Placement | Recommendation | Why |
|---|---|---|
| In the crib or by the pillow | Avoid | Too close; puts a device and cable in the sleep space |
| On the crib rail or corner | Avoid | Close, and it can fall |
| Dresser or shelf across the room | Recommended | Distance lowers the level; out of reach |
| Near the door | Depends | Helps mask noise from the rest of the home |
Use a timer and a fade-out
If you only want sound while your baby falls asleep, use a timer. An abrupt stop can make a baby stir, so pair the timer with a fade-out that lowers the sound slowly at the end. If you prefer sound all night, keep it even quieter, or restart it only around the time your baby usually wakes early.
The start matters too: sound that eases in over a few seconds is less startling than sound that begins at full volume.
How to set this up in Lullawave
Lullawave has a volume for each layer, which makes it easy to keep the total level low. Choose a timer from 15 minutes to 1.5 hours or none, and a fade-out from 10 seconds to 3 minutes; playback always eases in over 5 seconds. Turn on the early wake guard to restart your last mix at a set time, such as 04:30, so you do not need to keep it running loud all night. Every ad is muted, so an ad never makes the volume jump.
