Beach waves is a real field recording of surf on the beach at Punta Allen, in the Sian Ka'an Biosphere Reserve on the Caribbean coast of Quintana Roo, Mexico. Felix Blume recorded it on November 1, 2015, and released it into the public domain.
What you're hearing
Waves that rise and fall slowly, with no sudden sounds in them. What plays here is a loop of twenty to forty seconds, cut from the original three-minute recording, so a close listener may notice it come round. It plays softer than the other sounds, to keep the waves natural; push its slider to about 85% and it matches them. It is the heart of the Relax mix, with green noise low underneath.

Listen safely
This is a sound, played back through whatever speaker or headphones you already own. It doesn't diagnose, measure, or promise anything about how you sleep, focus, or feel — it's just noise and a handful of real recordings, mixed the way you like them.
Keep the volume low enough that you'd still notice a smoke alarm, a phone ringing, or someone at the door. If you fall asleep in headphones, choose a volume and a pair you'd be comfortable wearing all night, and a session length that ends when you'd want the sound to stop.
If you use this near a baby, keep the speaker several feet from the crib, never inside or clipped to it, and keep the volume low — the same care you'd take with any sound machine in a nursery.
If your relationship with sound, or with sleep, feels difficult rather than simply restless, a doctor or audiologist is the right person to talk to. This is a mixer, not a clinician.
Is this a real recording of the sea?
+
Yes. It is a field recording made on the beach at Punta Allen, Quintana Roo, Mexico, on November 1, 2015, by Felix Blume. Nothing in it is synthesized. What plays here is a loop cut from it, with its level matched to the other sounds.
Who recorded it, and can I use it myself?
+
Felix Blume, who released it under CC0, a public domain dedication, so anyone may use it for anything without asking. The link under "Where the sound comes from" goes to the original upload.
Why is it quieter than the other sounds?
+
Its waves have a wide natural rise and fall. Raising it to the same loudness as the rest would have meant flattening them, so it plays about half as loud instead. Push its slider to about 85% and it matches.
Can I mix it with other sounds?
+
Yes. Tap Relax to hear it with green noise underneath, or add any other sound on this page by hand, up to six at once.
