How to use the ocean sounds player
- Press Play (or the Space bar). The sea fades in over a couple of seconds.
- Choose the Sea: a Calm bay with slow, small waves, a Beach with steady surf, or a Rough sea with bigger, more frequent breakers. Switching cross-fades smoothly from one to the other.
- Move the Distance slider to the right for a softer, more muffled sound, as if you had walked up the beach or were listening from a room with the window open. It takes the edge off the hiss of the surf, which many people prefer at night.
- Set the Volume and a Sleep timer. The waves fade out over the final 45 seconds rather than stopping suddenly.
Your sea, distance, volume and timer settings are remembered in this browser. On a phone, keep the tab open and lock the screen; on most phones the waves carry on in the background and show up in the lock-screen media controls.
How the waves are made
This page plays no recordings. Your browser builds every wave from filtered noise, following what actually happens on a shore:
- The swell and the break: as a wave approaches, its low roar grows and gets brighter, peaks as it breaks, then slowly fades as the water washes up the sand and drains back. The player shapes a band of pink noise with that rise-and-fall, opening a filter as the wave builds so it sounds fuller and closer at the break.
- The surf hiss: the white foam of a breaking wave is a burst of high-frequency hiss. A separate layer adds it on the break and lets it fade away over the following seconds.
- An irregular rhythm: real waves do not arrive like a metronome. Two or three wave layers run at different speeds, each slowly drifting, so one wave arrives roughly every 6 to 14 seconds, some bigger than others, sometimes overlapping, from slightly different directions.
- The sea itself: a quiet, low rumble of brown noise sits underneath, so the sea never falls completely silent between waves.
Everything is generated continuously by the audio engine, with no clips to schedule. That means the waves keep their natural rhythm even when your phone locks the screen and pauses the page's scripts.
Calm bay, beach or rough sea?
| Sea | What you hear | Often chosen for |
|---|---|---|
| Calm bay | Slow, small waves and a soft wash, little hiss | Falling asleep, meditation, slow breathing |
| Beach | Steady surf with a clear break and wash | Relaxing, reading, a holiday feeling |
| Rough sea | Bigger, faster, brighter breakers and a deeper roar | Masking louder noise such as traffic |
The slow rise and fall of a calm sea is one reason people like it for winding down: some find it easy to breathe along with the waves. If you prefer a sound that does not change at all, a steady noise colour may suit you better; our guide white, pink and brown noise: what's the difference? explains how they compare.
Do ocean sounds help you sleep?
Ocean waves are a favourite relaxation sound, and for many people they make it easier to switch off. Part of the effect is masking: a constant background makes sudden noises less noticeable, so they are less likely to disturb you. Part of it is personal: many people associate the sound of the sea with holidays and rest.
The scientific evidence is limited. Research on background sound for sleep is mixed, with some studies reporting benefits and others finding none, and reviews rate the quality of the evidence as low. Note also that waves are not perfectly steady: their rise and fall masks noise less evenly than a constant sound such as pink noise or a fan. If a noise keeps waking you in the quiet moments between waves, choose the Calm bay preset, move further away, or blend the waves with a steady noise in the sleep sounds mixer. Ocean sounds are a comfort, not a treatment for insomnia, anxiety or tinnitus; if sleep problems persist, talk to a doctor.
Safe volume
Keep the sea at a gentle level, below normal conversation and just loud enough to soften the sounds around you. Waves have louder moments at each break, so set the volume during a big wave rather than in a quiet moment. With earphones, keep it low for long or overnight listening, and consider a speaker across the room. The player's volume is capped, but your device volume adds to it. To check your hearing, try the online hearing test.
Privacy: the waves are generated on your device by your browser's Web Audio engine. No audio is downloaded or uploaded, and the only data stored is your settings, in this browser's local storage. You can also listen to rain sounds or browse all sleep and relaxation sounds.
Frequently asked questions
Do the ocean sounds loop?
No. The waves are generated live and their rhythm drifts continuously, so no two minutes are the same and there is no loop point or gap.
Will the waves keep playing when my phone screen is off?
On most phones, yes. Keep the browser tab open and lock the screen. Because the waves are made entirely inside the audio engine, they keep their natural rhythm in the background. Closing the tab or the browser stops them.
Which ocean sound is best for sleep?
Many people prefer the Calm bay at a low volume, moved a little further away, because it has the gentlest changes. If you need to cover louder noise, a beach or rough sea masks more. Try a few minutes of each.
Can I mix ocean waves with rain or white noise?
Yes. The sleep sounds mixer uses the same waves and lets you add rain, wind, a fire, a stream, a fan or any noise colour, each with its own volume, and save the mix.
Are ocean sounds good for babies?
Some parents use gentle waves to settle a baby. Keep the volume low and the speaker away from the cot, and use a timer. Our guide is white noise safe for babies? explains volume and distance, and the white noise for babies page has shushing and heartbeat sounds.
Why are there no seagulls?
Synthesised birds tend to sound artificial and sudden calls can wake light sleepers, so the player sticks to the sea itself: waves, surf and the low rumble of the water.
