Waves are the one sleep sound with a pulse — a slow, regular rhythm your breathing settles into without being asked. Preview NoiseTape's shoreline below, alongside its calmer cousins: lake water and a flowing river.

02 — WHY IT WORKS
Most masking sounds work by being constant. Waves work by being rhythmic: a swell builds, breaks, washes out, and returns roughly every eight to twelve seconds — close to the cadence of slow, relaxed breathing. Listeners tend to sync to it unconsciously, which is why wave audio feels less like background noise and more like being paced to sleep. Underneath the rhythm, the broadband wash of water still masks voices and traffic like rain does.
The recording matters more here than with any steady noise: waves that crash too close jolt instead of soothe. NoiseTape's waves keep the break soft and the rhythm even, loop seamlessly for a full night, and play offline with the screen locked. If the pulse of surf turns out to be too much motion for you, the lake and river scenes give you the same water without the swell.
03 — FAQ
Waves combine two mechanisms: broadband water sound that masks disturbances (like rain or pink noise does), and a slow, regular swell rhythm — roughly every ten seconds — that relaxed breathing naturally falls into step with. Constant noise only does the first; the shoreline does both at once.
Different tools. White noise is perfectly steady and masks hardest; waves trade a little masking for rhythm and atmosphere, which many people find easier to fall asleep to. If you wake often to noise, try white or brown noise; if your problem is switching off, waves are the better first pick. NoiseTape includes all of them.
Yes. This page previews three water scenes from NoiseTape's catalog: ocean waves for rhythm, lake water for gentle lapping with almost no swell, and a river for continuous flow. Waterfall and rain scenes go further still — all of them seamless, offline loops.
Yes — NoiseTape's waves are a seamless, gap-free loop tuned for 8-hour sessions, with no fade or restart seam where the recording repeats. It plays offline with the screen locked on iPhone, iPad and Mac, and the sleep timer washes the volume out gradually in the final minute.
