Sounds for Sleep
A consistent, gentle sound masks the noises that jolt you awake and gives your mind something steady to settle on. This mix blends calm night ambience with a soft crackling fire. Set a sleep timer so it fades out on its own after you drift off.
The noise colors (white, pink, brown, green & gray) generate real audio in your browser. Loop-based channels play once their audio files are added.
Frequently asked questions
Can I leave Soundlull playing all night?
Yes. Sounds loop seamlessly and will keep playing as long as the tab is open. If you'd rather it stop on its own, use the sleep timer to fade everything out after 15, 30, or 60 minutes.
Do rain sounds help you sleep?
Rain produces gentle, broadband noise that masks abrupt sounds and gives your mind a steady, low-stakes thing to focus on, which many people find makes it easier to fall and stay asleep. Pair it with a sleep timer so it fades out after you've drifted off.
What's the difference between white, pink, brown, green, and gray noise?
They differ in how energy is spread across frequencies. White noise is flat and bright, pink is balanced and natural, brown is deep and bass-heavy, green concentrates on the mids like rushing water, and gray is shaped so every pitch sounds equally loud. Try each and use whichever you find most comfortable.
