White vs pink vs brown noise: listen and compare

Hear short white, pink and brown noise samples side by side. Compare their sound and frequency balance with a simple player and printable reference.

Free to use Part of Playbook 10

Explore what these sounds are like while awake. This is a short listening comparison, not a sleep treatment or an overnight sound player. Silence is also a valid preference.

A small listening room

Three textures. Your own ears.

Turn your device volume down before starting. Keep the sound low and stop if it feels uncomfortable. This player cannot measure decibels or certify a safe listening level.

Sample lengthPlayer level 15% player level

The percentage controls this player only. Your device volume, speakers and headphones determine the actual loudness. Samples may feel different in loudness at the same setting.

Choose a sound below. Nothing plays automatically.

Sound 1

White noise

Brighter, hiss-like

Illustrative energy slope, not a live measurement

Sound energy is spread evenly per frequency interval. Compared with the other examples, higher frequencies are more prominent.

Sound 2

Pink noise

Less bright, fuller

Illustrative energy slope, not a live measurement

Energy per frequency interval falls as frequency increases. Lower frequencies have more weight than in white noise.

Sound 3

Brown noise

Deeper, rumble-like

Illustrative energy slope, not a live measurement

Energy falls more steeply with increasing frequency. Low frequencies have more weight than in pink noise.

The sound is only part of the story

What this comparison can tell you

The samples illustrate different frequency balances. They are digitally generated, band-limited sounds. The drawings use a logarithmic frequency scale; their vertical positions are schematic, not loudness readings. Small speakers may reproduce little of the deepest sound.

Finding a sound pleasant does not show that it improves sleep. A 2026 Penn Medicine sleep-lab study found reduced REM sleep during pink-noise exposure in its test conditions. It does not settle every listening situation, but it is a reason to question blanket sleep-benefit claims.

For sleep, NHLBI recommends a quiet, cool, dark bedroom. Persistent sleep difficulties deserve a conversation with a healthcare professional. This tool does not choose a treatment, mask a medical symptom or test your hearing.

Only one sample plays at a time. Playback stops when this page goes into the background and does not restart by itself. No microphone or audio upload is used.

Make the most of this tool

Hear the difference between white, pink and brown noise

Lower your device volume first, choose a short sample length, and press Listen on one sound. Adjust the player level gently or stop at any time. Compare the written frequency explanations and print them as a reference.

Which noise color is best for sleep?

This comparison does not select a best sound or promise a sleep benefit. Liking a sound is different from improving sleep. Research remains limited, and a recent sleep-lab study found reduced REM sleep with pink noise in its test conditions.

Does 15% player level mean the sound is safe for my ears?

No. The percentage is a digital player setting, not a decibel measurement. Actual loudness depends on your device volume and output equipment. Keep the sound low, limit listening, and stop if uncomfortable.
