THE SOUNDS
Not all noise
is the same.
White, pink, brown: they cover different frequency ranges and feel entirely different to sleep to. Here's what each one actually does.
-
White Noise
All frequencies, equal volume
Covers the full frequency spectrum at equal intensity, creating the broadest possible sound blanket. Most effective at masking sudden, unpredictable noise like doors, traffic, and voices.
BEST FOR
Light sleepers, loud environments, offices, and anyone who needs maximum sound masking.
-
Pink Noise
Softer, deeper than white
Equal energy per octave, naturally heavier in the bass frequencies. Sounds like steady rainfall or a gentle wind. Many people find it more relaxing and easier to fall asleep to than white noise.
BEST FOR
People who find white noise too harsh or bright. Also studied for its effect on memory consolidation and deeper sleep quality.
-
Brown Noise
Deep, bass-heavy
Even more energy in the low frequencies than pink noise. Rich, deep sound, like heavy rain, a strong river, or the inside of an airplane. Preferred by people who want a deep, immersive sound environment.
BEST FOR
People with tinnitus, those who find white noise too thin, and anyone who prefers a heavier, more enveloping sound.
-
Nature Sounds
Rain, ocean, forest
Recorded natural environments: rain on a window, ocean waves, forest ambience. Less about masking and more about creating a calming atmosphere. Work especially well for relaxation before sleep or light napping.
BEST FOR
Meditation, relaxation, light sleepers who prefer ambient sound over pure noise.
-
Lullabies
For babies and young children
Gentle, melodic sleep sounds designed for infant and toddler sleep. Calming rather than masking, helps babies associate the sound with sleep and transition into rest more smoothly.
BEST FOR
Newborns, infants, and toddlers. Perfect for nursery machines and bedtime routines.

WHY IT WORKS
The case for
more options.
Fan-based is the classic. Multi-sound is the flexible. Here's when more options is the right call.
-
Find what works for you.
White noise doesn't work for everyone. Pink noise, brown noise, and nature sounds reach different frequency preferences. Multi-sound machines let you test and settle on what your brain actually responds to.
-
One machine, whole household.
You might prefer brown noise. Your partner might want rain. Your baby needs lullabies. A multi-sound machine handles all of it, without buying a different device for every room or every person.
-
Night lights and timers built in.
Multiple models include dimmable night lights and sleep timers, features that fan-based machines don't offer. For nurseries, for travel, and for anyone who wants it to wind down once sleep takes hold.
-
Portable and rechargeable.
Fan-based machines need a power outlet. Most multi-sound machines charge via USB-C and run on battery. Clip to a stroller, run off a power bank, or use them in any room, any trip.

Good questions.
Honest answers.
Everything you want to know about multi-sound machines.
White noise covers all frequencies equally, like a steady fan or TV static. It's the broadest sound mask and works well for blocking a wide range of disruptive sounds. Pink noise has more energy in the lower frequencies. It sounds like rain or a steady wind, and many people find it softer and easier to sleep to. Brown noise goes even deeper, with a rich, bass-heavy quality like a strong river or heavy rain. None is objectively better. It's about what your brain responds to. Multi-sound machines let you actually try each one and find out.
Try them. Most people settle on a preference within a few nights. A good starting point: if you've ever slept well near a fan or AC unit, start with white noise. If you find white noise too harsh or bright, try pink noise. If you want something deeper and more immersive, try brown noise. Nature sounds work better for relaxation than for blocking noise. Lullabies are designed specifically for babies and young children.
They work differently. Fan-based machines use real mechanical sound that never loops. Some light sleepers find this more effective because their brain genuinely can't detect a pattern. Multi-sound machines play recorded audio files, which are very high quality but technically repeat. For most people, the difference is imperceptible. Multi-sound wins on flexibility, portability, and features. Fan-based wins on mechanical authenticity and simplicity. Both work well.
Depends on the model. Many Yogasleep machines have physical controls only — buttons or dials, no app required. Some premium models offer optional app control for additional features like custom sound mixing, timers, or brightness adjustment. App control is always optional, never required to use the core sound function.
Depends on how you'll use it. For a nursery: look for a night light and a timer. For travel: prioritize battery life and size. The Hushh family has up to 80 hours of battery life and clips onto gear. For a home bedroom: sound variety and volume range matter most. For focus and office use: white or brown noise at consistent volume, simple controls. If you're not sure, the Find Your Collection section above routes you to the right starting point.
Some models are designed specifically for babies — the Nod, Soundscene, Hushh family. Others are adult-focused but work fine for children too. The key factors for baby use are volume range (should go low enough for infant-safe levels), whether it has a night light, and whether it has a timer. Always check individual product specs and follow AAP volume guidelines for infants..
