Pink Noise
Pink noise reduces power as frequency rises, so it sounds fuller and more natural than white noise — closer to steady rainfall. It's a popular choice for deep, restful sleep. Soundlull generates it live, no download needed.
White, brown & pink noise generate real audio in your browser. Loop-based channels play once their audio files are added.
Frequently asked questions
What is pink noise?
Pink noise reduces power as frequency rises, so it sounds fuller and more natural than white noise — close to steady rainfall. It's a common choice for sleep because it's easy on the ears.
What's the difference between white, pink, and brown noise?
They differ in how energy is spread across frequencies. White noise is flat and bright, pink noise is balanced and natural, and brown noise is deep and bass-heavy. White can sound hissy, pink sounds like soft rain, and brown sounds like a low rumble. Try each and use whichever you find most comfortable.
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.
