Tonight’s routine
- Lower stimulation 30-45 minutes before bed (lights, screens, caffeine).
- Start a low-volume brown noise loop and keep it stable.
- Use slow breathing for 2-3 minutes when your mind feels active.
- If you wake at night, keep lights low and restart the same loop pattern.
- Keep the same routine for 7 nights to evaluate consistency.
The technical difference
- White noise has equal energy across all frequencies — from deep bass to high treble. This is why it sounds "hissy" or like static.
- Brown noise rolls off at 6dB per octave — meaning higher frequencies are much quieter. The result is a deeper, warmer sound with almost no hiss.
- Pink noise sits in between: it rolls off at 3dB per octave. It's softer than white, brighter than brown.
- The frequency profile matters because human hearing is most sensitive to mid-high frequencies. White noise stimulates this range more, which some find energizing rather than calming.
- Both types effectively mask environmental noise — the difference is in how they feel during extended listening.
When to choose brown noise
- You find white noise too sharp, hissy, or stimulating — this is the most common reason people switch.
- You're sensitive to high-frequency sounds (tinnitus, hyperacusis, or general noise sensitivity).
- You want a "cocooning" feeling — brown noise's low frequencies create an enveloping sensation.
- You're using sound for middle-of-night wake-ups where sensitivity is highest and sharp sounds feel jarring.
- You prefer sounds described as: waterfall, distant thunder, deep wind, or ocean waves.
When to choose white noise
- Your main problem is environmental noise masking (traffic, neighbors, snoring) and you need maximum coverage across all frequencies.
- You're already comfortable with white noise and have a positive sleep association with it.
- You live in a very noisy environment where the broader frequency coverage of white noise provides better masking.
- You use sound primarily for focus/work and want something more stimulating than brown noise.
- You find brown noise too "muffled" or not distinct enough from silence.
What to expect when switching
- If switching from white to brown: the first night may feel "too quiet" because high-frequency masking is reduced. Give it 3-5 nights.
- If switching from brown to white: you may notice more awareness of the sound itself. This usually fades as you adjust.
- Most people who switch from white to brown and stay have cited "comfort during long listening" as the key factor.
- You don't have to choose one forever. Some people use white noise for noisy environments and brown noise for quiet bedrooms.

Frequently asked questions
Can I mix brown and white noise?
Yes — some apps let you blend frequencies. A 70/30 brown-to-white ratio gives you depth with some additional masking. Our Brown Noise app includes customizable sound mixing.
Is pink noise a good compromise?
Pink noise is often described as "brown noise lite." It has more high-frequency content than brown but less than white. It's worth trying if neither extreme feels right.
Which is better for babies?
White noise is traditionally used for babies because it mimics womb sounds. For adults, brown noise is often preferred. Soothy offers sound profiles designed specifically for infant sleep.
Does the science favor one over the other?
Research on noise color for sleep is limited. Most studies use "white noise" as a catch-all for any continuous sound. The few studies comparing colors suggest individual preference matters more than any objective measure.
What about noise-canceling headphones instead?
ANC removes sound; sleep noise adds sound. They solve different problems. Some people use both — ANC to block sharp sounds + brown noise to fill the resulting quiet. For sleep, a speaker is usually more comfortable.
Will I become dependent on sleep sounds?
Using a consistent sound cue is no different from preferring a dark room or a comfortable pillow. It's a sleep environment preference, not a dependency. You can sleep without it — you just sleep better with it.
