White vs Pink vs Brown Noise: Which Is Best for Sleep & Focus?
Updated: 3 hours ago
White, pink and brown noise are the most popular sounds for sleep and focus, but they sound quite different. This guide compares them side by side, along with blue and green noise, explains what research does and doesn’t say, and helps you choose. Each colour links to its own detailed guide.
What is coloured noise?
Noise is a random sound that covers many frequencies at once. Its “colour” describes how the energy is spread across low and high frequencies, borrowed loosely from how light colours work. White noise is evenly spread, so it sounds bright. Pink and brown shift energy toward the low end, so they sound softer and deeper.
White vs pink vs brown noise at a glance
Noise | Sounds like | Frequencies | Often used for |
Static, a fan, a hair dryer | All equal: bright | Masking noise, sleep, babies | |
Steady rain, wind in trees | Softer highs: balanced | Sleep, relaxation | |
Waterfall, distant thunder | Strong lows: deep | Sleep, focus, ADHD focus | |
Waterfall, forest | Middle range (not a standard term) | Sleep, relaxation | |
Light hiss or spray | Stronger highs: bright | Masking voices, alertness |
Which noise is best for sleep?
There is no single best colour. Many people start with white noise because it masks the most, then switch to pink or brown if they find it too hissy. A 2021 systematic review of noise as a sleep aid found the overall evidence low quality, so the best choice is the one you find most comfortable at a low volume.
How to choose
Noisy street or neighbours: white noise masks the widest range of sounds.
White noise feels harsh: try pink noise.
You like a deep, rumbling sound: brown noise.
You want something natural: green noise or rain and forest sounds.
Masking voices during the day: white or blue noise.
Focus and studying: brown or pink noise, or try beta binaural beats.
How to use noise safely
Keep the volume low, around the level of a quiet conversation or lower.
Place the speaker away from your head, not on your pillow.
Speakers work fine; you don’t need headphones for noise.
For babies, keep the device well away from the crib and the volume low.
If you use it all night, a sleep timer or a gentle fade-out can help.
