Evidence and listening guidance
Steady sound can mask environmental noise, but sleep, focus, and relaxation responses vary by person. This page does not claim that a sound color treats a health condition.
Use the lowest comfortable level that does the job and take listening breaks. A browser or device volume slider is not a calibrated decibel meter, so it cannot prove an exact sound level at your ears.

Why Brown Noise and Rain Work Together
Brown noise concentrates its energy in low frequencies, which makes it feel more like a distant rumble than a hiss. That low-end weight is what smooths over the sounds most likely to wake you: doors closing, footsteps upstairs, a car idling outside. On its own, though, pure noise can feel sterile. The light rain layer adds gentle, irregular texture on top, and your brain reads that randomness as natural rather than mechanical. Together you get a sound that masks disruptions like a machine but feels like falling asleep during a rainstorm. The mix sits at 70% brown noise and 40% rain by default, which keeps the rain present without letting individual drops grab your attention.
What's in This Mix
Brown Noise
70% volumeThe foundation of the mix. Its deep, rumbling character masks low-frequency disturbances like traffic and slamming doors that white noise often misses.
Light Rain
40% volumeAdds soft, natural texture over the noise floor so the blend feels like weather instead of a machine. The gentle patter gives your mind something calm to settle on.
When to Use This Mix
Reach for Deep Sleep when your main problem is noise: thin walls, a snoring partner, early garbage trucks, or a city street below your window. The brown noise floor is what does the masking work, so this blend earns its keep in loud environments where lighter nature mixes fall short. It also suits people who find pure rain too sparse — the noise layer fills in the gaps between drops so nothing pulls you back to the surface. Start it ten or fifteen minutes before lights out so the sound is already part of the room by the time you close your eyes.
How to Tweak It
Use the Remix button to open this blend in the full mixer, then tweak it there. If the mix feels too heavy, pull brown noise down to around 50% and let the rain carry more of the texture. If you live somewhere genuinely loud, do the opposite: push brown noise up and drop the rain to 20% so the masking floor stays solid. Keep your overall device volume at the level of a quiet conversation or below — masking works by raising the floor under disruptive sounds, not by being loud. Save your version when it sounds right.
What to Try Next
If you like the idea but want more rain and less rumble, Night Rain flips the proportions of this exact pairing. If low frequencies are what soothe you, try pure brown noise on the Deep Work mix at a lower volume, or explore the Rainy Window mix for rain on glass with distant thunder rolling underneath.
Frequently Asked Questions
Is brown noise better than white noise for sleep?
Many people find brown noise more comfortable because its energy sits in lower frequencies, so it sounds like a soft rumble rather than a hiss. White noise masks a slightly wider range, but comfort matters most for sleep — the best choice is whichever one you stop noticing first.
Can I leave this mix playing all night?
Yes. The mix plays on a loop with no ads or interruptions, and many people sleep better with continuous sound because it keeps the noise floor steady through the night. If you prefer it to stop, use the sleep timer in the full mixer.
What volume should I use for sleeping?
Quieter than you think. Set it just loud enough to blur the sounds that usually wake you — roughly the level of a soft shower running in another room. If you have to raise your voice to talk over it, it is too loud.
Can I change the balance of rain and brown noise?
Yes, in the full mixer. This page has one volume slider for the whole blend; the Remix button opens it in the full mixer, where each layer has its own slider and you can add more sounds, save your version, and share it with a link.
