Frequently asked questions
What's the difference between white, pink and brown noise?
White noise has equal energy at all frequencies (hissy). Pink noise falls off gently (like rain). Brown noise is deeper still (like a waterfall).
Does brown noise help focus?
Many people find its low rumble masks distractions — evidence is mixed, but it's worth trying.
Does it use data?
No — the noise is generated live in your browser, so there's nothing to stream.
