How these waves play, and how they differ from a steady hiss

Point	These waves
Rhythm	The waves rise and fall, so the level changes all the time.
Loop length	About 3 minutes long, in 48 kHz stereo. The same wave does not come back for 3 minutes.
File sizes	One hour of waves is about 140 MB as MP3, or about 440 MB as FLAC, which has no loss.
Steady noise	White, pink, and brown never change level. Waves move, so some people find them easy to follow and others find them harder to ignore.
Waves with rain	Add Rain for a storm at sea, or Fan for waves heard from a room. You can mix up to 3 sounds.
Loop	The loop repeats with no gap, so the waves never jump or click.

Level and timer
Long, loud listening can damage hearing, as the Sleep Foundation notes. Keep the waves low and set 30, 60, or 120 minutes. The sound fades over the last minute.
Play all night on a phone
Choose No timer, and the waves go on until you stop them. Keep the browser tab open and the phone on charge. Playback with the screen locked is not promised.
Waves for sleeping
If the rise and fall keeps you awake, lower Ocean and add Pink. The steady layer fills the quiet between waves.
Dark screen
Tap Dark screen and the room stays dark. Tap once to bring the player back.

Where can I get free ocean sounds for sleep?: In your browser. Play the waves and download a file, both at no cost and with no sign-up.
How do I play ocean sounds on my phone?: In the phone browser, tap Play. Set the timer, then tap Dark screen. Keep the tab open, because we do not promise sound with the phone locked.
Why do ocean sounds help you sleep?: Some people find the slow rhythm calm, and the wash covers sudden sounds. Ocean sounds for relaxation are popular for that reason. The Sleep Foundation says some studies found people fell asleep faster with white noise, and reviews call the evidence mixed and of low quality.
Are ocean sounds good for sleep?: They can be for some people. Ocean sounds for sleeping work best at a low level. Try one night with ocean sounds. Sleep with the timer at 60 minutes and see if you wake less. These sounds are not a medical device or medical advice.
Can I play ocean sounds all night?: Yes. With No timer, the waves play until you stop them. For another device, download one file of up to 10 hours.
Are ocean waves white or pink noise?: Neither. Real surf has most of its energy in the low notes, so it is closer to brown or pink noise than to white.
What is the difference between ocean sounds and white noise?: White noise stays at one level and hisses. Ocean noises rise and fall, and they have far less hiss. That is wave rhythm vs steady noise.
