Noise for Babies
Audio is synthesized live in your browser — nothing is downloaded. Press play to start.
Parents often play a steady “shushing” sound near a crib because it resembles the muffled whoosh a baby heard before birth. Pink and white are the usual choices — this page defaults to the softer pink. It is a simple sound generator, so you can leave it running or use the sleep timer to fade it out.
Keep the volume low and place the device well away from the crib. This tool is a plain sound generator and makes no medical or safety claims — follow your pediatrician's guidance on infant sleep and safe sound levels.
The noise colors
- White — Flat, full hiss.
- Pink — Balanced, softer.
- Brown — Deep low rumble.
- Blue — Bright, airy hiss.
- Green — Mid-focused.
Every color here is generated from scratch with the Web Audio API the moment you press play — there are no sound files to load and nothing leaves your device. That is also why it keeps working offline once the page has loaded.
