Brown noise vs pink noise: which for sleep and focus?
In this guide
The short answer · How they differ · Sleep & focus · Which to pick
The short answer: these are the two gentlest colors, both far easier on the ears than white noise. Brown noise is the deepest - a low rumble. Pink noise is a step brighter - a warm, even, rain-like sound. Most people prefer one by feel.
How they differ
Brown noise drops about 6 dB per octave, pink about 3 dB. So brown stacks the most energy at the low end (distant thunder), while pink keeps more of the mids (steady rain). Both avoid white noise's bright hiss.
You want the deepest, most grounding rumble - calming a racing mind, deep focus, all-night listening.
You want a lighter, natural, rain-like warmth - relaxing, reading, easy sleep.
For sleep and focus
