Plenty of people put some steady sound in a bedroom at night — a fan, an air conditioner, or a page like this one propped on a nightstand. Reasons vary: a quiet room where small sounds stand out, a shared wall, street noise through a window, a habit built over years.
Night wetland, or something else
This page opens on the Sleep mix: night wetland, a real recording from Mexico's Yucatán Peninsula, with brown noise low underneath for a steady floor. Press play once and it starts. The noise colors on their own, and the other real recordings, are one tap away below if you'd rather make your own. The Sleep mix is set to all night; choose a shorter length if you like, and it fades out on its own when the time is up.
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.
What sound should I use at night?
+
There's no single answer — it's a matter of taste and what's in the room with you. Some people prefer a flat, even hiss like white noise, some prefer the deeper, rounder character of brown or green noise, and some prefer a real field recording, like the wetland at night this page opens on. Every sound on this site is one tap away from the others here, so trying them side by side is the easiest way to find out.
Why does this page open on night wetland and brown noise?
+
Night wetland is a real recording of a wetland after dark, made near Felipe Carrillo Puerto in Quintana Roo, Mexico. Brown noise sits low underneath it as a steady, rounded floor, and it starts the moment you press play, while the recording is still arriving. Any other sound is one tap away if you'd rather make your own mix.
Will the sound keep playing after I fall asleep?
+
Only for as long as you choose. The Sleep mix is set to all night, which is eight hours; fifteen, thirty, sixty and ninety minutes are there too. When the time is up the sound fades out on its own rather than stopping suddenly.
Is it safe to sleep with headphones in?
+
If you do, choose a volume and a pair of headphones you'd be comfortable wearing for the length of the timer, and keep the volume low enough that you'd still notice an alarm. The listen safely note below has more detail, and it applies here the same as everywhere else on this site.
How loud should this be at night?
+
Low enough that you'd still notice a phone ringing, a smoke alarm, or someone at the door — the same rule this site uses for every sound, at any hour. The listen safely note below has more detail.
