Full walkthrough of every sound generator, layer behaviors, presets, sleep timer, and shareable mixes — plus when to reach for each one.
How to use
- Press Play. Brown noise starts at a deep 0.5, pink noise at 0.35 — a balanced low-end bed.
- Slide each layer's volume independently to shape the color of the mix.
- Add a sleep timer (15/30/60 min) if you're using this to fall asleep.
- Save the mix as a preset so your exact brown/pink balance loads on the next visit.
FAQ
What's the difference between brown and pink noise?
Pink noise rolls off the high end by about 3 dB per octave, so it sounds balanced and natural. Brown noise rolls off twice as fast, so it sounds very warm and low — closer to distant surf or a rumbling HVAC.
Which one is better for sleep?
Most people prefer brown noise for sleep because the low-end emphasis is the least fatiguing and masks traffic or neighbours most effectively.
Can I add rain or thunder to this page?
Yes. Browse the Sound Library below and tap any sample to layer it on top of the noise bed.
Brown vs pink noise at a glance
Pink noise is "equal energy per octave" — it feels balanced across the
whole audible range and sits well under conversation or music. It's a solid
default for long focus blocks.
Brown noise doubles down on the low end. It's darker, warmer, and the
most forgiving single-layer choice for sleep or heavy masking.
Recommended uses
- Sleep — brown 0.55 alone, or brown 0.5 + a whisper of rain.
- Focus — pink 0.5 alone, or pink 0.35 + rain 0.3 for a softer top end.
- Masking traffic — brown 0.55 + distant thunder for extra low-end randomness.
