Noise color guide
Brown noise vs white noise vs pink noise
White noise is the brightest, pink noise is softer and more balanced, and brown noise is the deepest. Listen at one volume to hear the difference for yourself.

Compare the three noise colors
Only one plays at a time. Start with a low volume, then switch colors without moving the slider.
The difference in one minute
Choose white noise for a crisp, even hiss. Choose pink noise when white feels too bright. Choose brown noise when you want the least high-frequency hiss and the most low-end weight. None is universally better for focus or sleep; comfort at a low volume is the useful test.
Brown, white and pink noise compared
| Noise | Frequency balance | How it sounds | Try it when |
|---|---|---|---|
| White | Equal energy per hertz | Bright, steady hiss | You prefer a crisp, consistent sound |
| Pink | Energy reduces as frequency rises | Softer, balanced rush | White noise feels too sharp |
| Brown | High frequencies reduce more steeply | Deep, low rumble | You want less hiss and more low-end weight |
Brown noise vs white noise
White noise distributes energy evenly across individual frequencies, which gives it a noticeable high-frequency hiss. Brown noise rolls that energy down much faster as frequency rises, so it sounds lower and rounder. If white noise feels sharp, switch directly to brown without changing the volume.
White noise vs pink noise
White noise has equal energy at each individual frequency, while pink noise reduces energy as frequency rises. That makes white noise sound brighter and pink noise sound softer. Try pink when the hiss of white noise feels sharp, or white when pink noise feels too subdued.
Pink noise vs brown noise
Both reduce higher frequencies, but brown noise does it more strongly. Pink noise therefore sits between white and brown: less bright than white, but lighter than brown. Try pink when brown feels heavy or when white keeps drawing your attention.
How to compare fairly
Set a low volume, listen to each color for about 20 seconds, and switch without moving the slider. The same gain does not guarantee the same perceived loudness, so make one final small volume adjustment after choosing your preferred sound.
For focus, study or sleep
No noise color is automatically best for a task. Choose the least distracting option for focus, the easiest background to ignore while studying, or the gentlest sound at bedtime. Preference matters more than the label, and this tool is not a medical treatment.
