Ocean sounds
No timer
Space plays or pauses. B toggles the black screen.
Wind down for sleep with guided deep rest. Wind Down for Bed is a free 10-minute guided session. Noise plays in the background; this one you follow.
These waves aren't a recording. The player makes them in your browser: a slow swell that rises and brightens, a soft break of foam at the top, then a long hiss as the water runs back, over a quiet rumble of distant sea. Four waves of different sizes roll in every 30 seconds, so they don't tick like a clock. There are no gulls, no wind and no sudden crash. Because the sound is generated, there's no gap you can hear when it loops and nothing to buffer.

Long or repeated exposure at 85 dBA or more can cause hearing loss, so turn it up only until it covers the sounds that bother you. Put your phone across the room, not by your head.
In a 2026 sleep-lab study, a night of pink noise alone at 50 dB cut REM sleep by about 19 minutes. Ocean sounds weren't tested, but these waves are a broadband sound too, and the crests are louder than the gaps between them. So set the volume on a big wave: 50 dB is a ceiling, not a target. Set the timer so it fades out instead of playing all night. Basner 2026
No. The waves are made in your browser when you press play, from noise shaped into swells, breaks and backwash. That's why there's no loop point you can hear and nothing to download.
Ocean sounds rise and fall. White noise is an even hiss right up to the highest pitches. A steady sound covers sudden noises more evenly, because the quiet gaps between waves cover less. Neither has good evidence for sleep, so pick the one you stop noticing.
Nobody has tested a whole night of ocean sounds at home. The closest result is the 2026 study where a night of pink noise at 50 dB cut REM sleep. If you need it all night to cover traffic or a snoring partner, keep the loudest waves under 50 dB and the phone across the room. If you only need help falling asleep, set the timer.
It plays through your browser like any other audio, so on most phones it keeps going with the screen locked and shows play and pause on the lock screen. If your phone stops it, turn on the black screen instead: it keeps the screen on but dark, so the page stays open.
