White, Pink & Brown Noise

White, pink or brown noise?
White noise has equal energy at every frequency, like a hiss or a fan — good for masking speech. Pink noise has more energy in the low frequencies, like steady rain, and many people find it softer. Brown noise is deeper still, like a strong waterfall or distant thunder, and is a common choice for focus and sleep.
Tips
- Keep the volume low enough to talk over it comfortably.
- Use the sleep timer so it fades out after you fall asleep.
- On phones, keep the screen on or the tab open; some browsers pause sound in the background.
FAQ
Is this safe for babies?
Keep any sound machine at a low volume and well away from the baby’s ears. Ask your pediatrician about recommended levels.
Does it use data?
No. The noise is generated on your device, so there is nothing to stream after the page loads.
Why is there no sound?
Check your device volume and silent switch, then press Play again — browsers only start audio after you click.
