This is the free Echo Sleep browser player. Switch between white noise, brown noise, pink noise, rain, fan, and ocean waves in one tap, set a sleep timer, and adjust the volume to suit your room. No download, no signup, no ads.
Each sound has its own profile and use case — and its own dedicated page with a deeper guide: white noise for sharp, unpredictable sounds; brown noise for low rumble and a softer feel; pink noise for a balanced, sleep-research-friendly texture; rain sounds and ocean waves for natural, meditative ambience; and fan sound for the familiar, steady bedroom-fan hum.
For all-night playback with 10+ sounds, AI sound creation, and reliable background audio on your phone, try the Echo Sleep app on iOS or Android.
White noise is generally considered safe for babies when used at a reasonable volume (below 50 dB, roughly the level of a quiet conversation). Place the sound source at least a few feet from the crib and avoid playing it at maximum volume. Many pediatric sleep specialists recommend white noise to help babies fall asleep faster and stay asleep longer.
White noise contains equal energy across all frequencies — it sounds like TV static or a hissing sound. Pink noise has more power in lower frequencies, sounding deeper and more balanced — think of steady rainfall. Brown noise is even deeper and richer, resembling a strong waterfall or distant thunder. Many people find brown noise the most soothing for sleep.
Yes! This player includes a built-in sleep timer with presets of 15 minutes, 30 minutes, 1 hour, and 2 hours. When the timer expires, the audio gently fades out over 10 seconds so you won't be jarred awake.
The audio will continue playing when the tab is in the background on most browsers. However, some mobile browsers may pause audio to save battery. For reliable all-night playback, we recommend the Echo Sleep app, which uses native audio services designed for continuous background playback.
