Noise sounds
Brown Noise for Sleep
Lower, rounder and less hissy than white noise. Brown noise has a deep, continuous character that some listeners prefer for a quiet background.

Why does brown noise sound deeper?
Brown noise has progressively less power at higher frequencies, with power falling roughly 6 decibels per octave. That gives it a low, rumbling character. Its name relates to Brownian motion, not the color of a physical sound source. A phone speaker may reproduce its bass differently from larger speakers or headphones.
Choose by sound, not by a promise
The words used to describe noise are useful for comparison, but do not predict how you will sleep.
A lower texture
Brown noise has more emphasis on low frequencies than white noise, so it can feel less sharp.
A steady background
Unlike ocean waves, there is no recurring swell to follow. Some people enjoy that consistency.
A natural alternative
Distant surf and dense rain offer a fuller background with small changes that synthesized noise does not have.
Try it without turning it up
A bass-heavy sound can seem quieter on a small speaker, so do not keep increasing the volume to chase bass your device cannot reproduce. Use a comfortable setting and compare with rain or ocean waves. The SleepBetter water collection offers natural recordings for listeners who prefer a less uniform texture.
A little more to explore
A few common questions.
Is brown noise better than white noise?
Neither is universally better. Brown noise is lower and less hissy, while white noise is brighter. Choose based on comfort and whether the sound stays in the background for you.
Is the brown noise sample from the app?
It is a standalone reference sample. You can hear actual SleepBetter recordings on the Rain and Ocean Waves pages.
