The ADHD community's open secret. Brown noise masks distractions without demanding attention. Free, no time limits, no account needed.
Start FocusingBrown noise sits in the low-frequency range — think distant thunder, a heavy waterfall, or the hum of a jet engine from inside the cabin. Unlike white noise (which covers all frequencies equally and can feel sharp), brown noise rolls off the highs and lets your brain settle into the deep, steady warmth underneath.
Your brain processes distractions by attending to changes in your environment — a door closing, someone talking, a notification sound. Brown noise creates a consistent sonic floor that masks those micro-interruptions. Nothing changes, so nothing grabs your attention. For people with ADHD, this can be the difference between a productive afternoon and a lost one.
