Sleep Sounds for Baby
Safe-volume white noise for nurseries.
Mix Layers
How to use
- Press Play — the preset starts at a lower volume than the default white noise page.
- Place the device at least 2 meters (6 feet) from the crib. Distance matters more than the volume slider.
- Use a timer (30m or 60m) so the sound fades once the baby is settled. The fade-out is gradual to avoid startling them.
FAQ
What is a white noise generator?
A white noise generator creates a steady broadband masking sound. This baby preset starts quieter than the general white noise page and is meant for nursery-style settling—not medical treatment.
Is white noise good for sleeping (babies)?
Many caregivers use steady masking sound to help babies settle. Follow safe levels and placement guidance, and confirm anything long-term with your pediatrician.
Can I use it for free?
Yes — playback is free in the browser on ZonoTools.
What is the difference between white noise and brown noise?
White noise is brighter and covers highs strongly. Brown noise emphasizes lows and can feel less hissy—useful if adults in the same room find white noise fatiguing.
Is white noise safe for babies?
Current pediatric guidance commonly cited online recommends keeping sound at or below ~50 dB at the crib and placing the source at least ~2 meters away. Verify levels in your room with a sound meter app.
Should I run it all night?
Many families use white noise to settle, then fade or stop once asleep. The sleep timer can fade out automatically.
Why white noise and not pink or brown?
White noise covers a wide frequency range, which can help mask sudden household noises. If the top end bothers you, try pink or brown variants from the mixer family.
Introduction
Getting quality sleep—for babies and parents—can be challenging in a noisy home. A white noise generator can provide consistent background sound that masks sudden household noises and helps a nursery feel calmer.
Using a white noise generator online gives you instant access without buying a dedicated white noise machine. This page is a baby-tuned preset: it starts quieter than the general white noise hub.
For broader mixing (rain, ocean, and more), explore Sound Generator—still keep levels conservative for infants.
What is a white noise generator?
A white noise generator produces a steady broadband signal. For sleep, the goal is a stable bed that makes unpredictable spikes less noticeable—without running unnecessarily loud.
Why use white noise for sleeping (babies)?
Using white noise for sleeping is a common caregiver strategy because:
- It can mask environmental noise
- It can help create a predictable auditory scene at bedtime
- It can be easier to standardize than “finding the perfect quiet house”
Many people rely on a sleep noise generator in the browser because it is accessible and easy to adjust.

What this preset does
A single layer of white noise at roughly 35% gain. That's lower than the
default white noise page because nursery use needs a safety margin — the
slider lets you raise it, but starting quiet means you won't ever accidentally
startle your child on Play.
Safety notes
- Keep the device at least 2 meters from the crib.
- Check levels with a sound meter app if you're unsure — aim for ≤50 dB at
the crib. - Use a timer instead of running the sound all night unless your pediatrician
specifically recommends otherwise.
The sleep timer fades to silence in the last few seconds rather than cutting
off abruptly, which is far less likely to rouse a sleeping baby.
