Here's what brown noise is, how it differs from white noise, and how to use it for focus.
What is brown noise?
Brown noise is random sound with most of its energy in the low notes, so it sounds deep and soft, like a strong wind. It's named after Brownian motion, not the color.
White noise has equal energy at every pitch, so it sounds like a hiss. Pink noise sits between the 2.

Does brown noise help you focus?

The deep work timer can play your sound for each session and stop it when you surface.
How to use the brown noise generator
How the noise is made
Brown noise is white noise added up over time, which takes out most of the high notes. The tool makes a few seconds of it and loops it, with the seam blended so it never clicks.
Ocean is brown noise through a filter that swells about every 11 seconds, like waves. During a session, it gets darker as you go deeper.
Final thoughts on brown noise
The right sound is the one you stop noticing after 5 minutes.
Start with brown noise at a low volume, and change it only if it gets in the way.
