Gray Noise
Gray (grey) noise is tuned to the ear rather than the meter: lows and highs are boosted and the mids relaxed, following an equal-loudness curve. The result sounds fuller and more balanced than white noise — often used to mask tinnitus and harsh office sound.
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 gray noise?
Gray (grey) noise is noise shaped to an equal-loudness curve: lows and highs are boosted and mids relaxed, so every frequency band sounds about equally loud to the human ear. It feels fuller and more even than white noise and is often used for sound masking and tinnitus relief.
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.
