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.
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
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, 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.
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.
