GUIDE · WHITE NOISE
Is white noise safe for babies? Volume, distance and timer tips
Many parents find that a little white noise or rain sound keeps their baby from waking at every door slam. White noise itself isn't the issue. The problems usually come from volume that's too high, a speaker that's too close, and a machine left at full blast all night. Here are three simple rules.
What white noise actually does
White noise is a steady, continuous sound without a melody, like a fan, a hair dryer or rain. It smooths out the ups and downs of household noise so sudden sounds are less jarring. It isn't an off switch for a baby. It makes the sleep environment more consistent.
Rule 1: Quieter than you think
Researchers who measured consumer infant sleep machines found that many could exceed hospital nursery noise recommendations at maximum volume. The practical rule: keep it at a level where you could have a soft conversation next to the crib without raising your voice.
- Start at the lowest setting and turn it up only until you can hear it.
- Listen from where your baby's head is. If it feels loud there, it's too loud.
- Never use sound to drown out your baby's crying. You need to hear them.
Rule 2: Keep the phone or speaker away from the crib
Distance changes how loud a sound is. The same setting is far louder next to a pillow than across the room.
- Don't put a phone or speaker in the crib, on the rail, or next to your baby's head.
- Place it across the room, out of reach.
- Keep charging cables well away from the crib.
Rule 3: Use a timer instead of running it all night
Many babies only need steady sound while falling asleep. A 30 to 60 minute sleep timer stops the sound once they're settled. If household noise keeps waking your baby, extend it as needed.
When to cut back
- If your baby can't seem to sleep without it, lower the volume and shorten the timer gradually.
- If anything about how your baby responds to sound worries you, such as not reacting to loud noises, talk to your pediatrician.
- If your home is quiet and your baby sleeps well, you may not need it at all.
How BabySleepTight is designed
BabySleepTight includes white noise, nature sounds, lullabies and ambience, with a sleep timer that stops playback after 15 minutes, 30 minutes or 1 hour, and playback that continues with the screen off, so you can keep your phone across the room. Play and volume sit together on one panel for one-handed use at night.
FAQ
Can newborns use white noise?
Many families use it from the newborn stage. The same rules apply: quiet, far away, on a timer, with safe sleep coming first. Ask your pediatrician if you're unsure.
Will my baby become dependent on it?
Some babies get used to sleeping with sound. To wean off, lower the volume and shorten the timer a little every few days.
Is it okay to play it from my phone?
Yes. Turn on airplane mode or Do Not Disturb to avoid notification sounds, and keep the phone out of reach and away from the crib.
