Baby sleep sounds
There are 16 baby sleep sounds in Agubu: eight free, eight in Premium. All of them play on your device; no internet is needed, no ad cuts in, and the sound does not stop because a connection dropped. The sleep timer fades the sound out slowly instead of cutting it, because what wakes a baby is sudden silence, not noise.
Every sound below has its own page: what it sounds like, when it tends to be chosen, and the safe volume. A week of trying and a sleep log will show which sound suits your baby; no sound works for every baby.
Noise
White noise for baby sleep
White noise for baby sleep is a steady sound that carries every frequency at roughly equal strength; to the ear it is a running shower or a fan in the next room.
Pink noise for baby sleep
Pink noise for baby sleep is white noise with the high frequencies turned down, so it sounds deeper and softer, like steady rain or a distant waterfall.
Brown noise for babies
Brown noise for babies is the deepest member of the noise family: the highs are almost gone, and what remains sounds like distant thunder or the low rumble of a big waterfall.
Womb and shushing
Womb sounds for baby sleep
Womb sounds for baby sleep imitate what your baby heard for nine months before birth: the muffled rush of blood flow, a steady pulse, and the outside world filtered through your bo
Heartbeat sound for baby sleep
A heartbeat sound for baby sleep imitates the most regular sound your baby heard for nine months before birth: the muffled, slow, unbroken beat of a resting heart.
Shushing sound for baby
A shushing sound for baby is the recording of what every parent does by instinct: a long, steady shhh close to the baby's ear.
Household sounds
Fan sound for baby sleep
A fan sound for baby sleep is the household sound many parents discover first: a steady hum with the soft, regular rhythm of the blades on top.
Vacuum cleaner sound for baby
The vacuum cleaner sound for baby is, in the words of the card in the app, the household sound parents report works most often; many families discover it when a crying baby goes qu
Car ride sound for baby sleep
A car ride sound for baby sleep exists for the parents of babies who fall asleep within five minutes in the car and will not settle at home: the hum of tyres on tarmac and the stea
Hair dryer sound for baby
The hair dryer sound for baby is the brighter, lighter sibling of the vacuum sound; many parents notice their baby settle while they dry their hair in the bathroom.
Nature
Rain sounds for baby sleep
Rain sounds for baby sleep are the one nature sound in the free eight, and the sound many adults choose for themselves: steady drops on a window over a soft background hiss.
Ocean waves for baby sleep
Ocean waves for baby sleep are the slowest-moving of the steady sounds: a nine-second cycle of a wave arriving, drawing back and arriving again, over the deep hum of the sea.
Stream sounds for baby sleep
Stream sounds for baby sleep are the continuous, lively hiss of water running over stones, brighter than rain and the most animated of the nature sounds.
Lullabies
Brahms lullaby for baby
The Brahms lullaby is the best-known lullaby melody in the world: the Wiegenlied Johannes Brahms wrote in 1868, played in Agubu in a soft music-box tone.
Mozart lullaby for baby
The Mozart lullaby is the Wiegenlied known by its opening line Schlafe, mein Prinzchen, schlaf ein (Sleep, little prince) and by its catalogue number K.
Schubert lullaby for baby
The Schubert lullaby is the Wiegenlied (D.
Noises, womb sounds, lullabies, nature
Noises: white noise masks sudden sounds; pink noise is softer than white; brown noise is the deepest and lowest. Womb sounds: womb sound and heartbeat resemble the environment before birth; shushing is the steady version of soothing in your arms. Lullabies: Brahms is free, Mozart and Schubert are in Premium — all public domain. Nature and household: rain is free; ocean, stream, fan, vacuum cleaner, hair dryer and car ride are in Premium.
Which noise colour for which situation
Infant-specific evidence does not show one colour beating another; the choice is about what your baby tolerates and what you need to mask. A rough guide:
- White noise — bright and hissy, like a shower. Masks sharp sounds best: doors, voices, a sibling. Tiring for adults at volume, so keep it low.
- Pink noise — softer, like steady rain. The middle ground for the whole night when white feels harsh; easier on a parent sharing the room.
- Brown noise — the deepest rumble, like distant thunder. Covers low sounds: traffic, a lift, the hum of the building. Phone speakers reproduce it faintly; do not turn it up to compensate.
- Womb sound and heartbeat — for the newborn weeks, when the only sound environment your baby knows is the one before birth.
- Shushing — for the fussy hour in your arms, the steady version of what you do by instinct.
Whichever you pick, the same rules apply: about 50 decibels, one to two metres from the cot, the timer set, and never all day while the baby is awake. All three noises, the womb sound, the heartbeat and shushing are free; try each for a few nights and let the sleep log decide.
Timer and mixer
The card for the playing sound offers 15, 30, 45 and 60-minute timers; when the time is up the sound fades out. The mixer in Premium layers up to 4 sounds at once, each at its own level. Sounds keep playing with the screen locked; the app can play audio in the background but can never record. The full feature: sleep sounds.
Safe use
Do not put the phone in or on the edge of the cot; keep it at least one to two metres away. Keep the volume low enough that you can speak in a normal voice in the room and be heard easily. Turning it down once the baby has settled is always a good move. For why it helps and how strong the evidence is, read White noise.
Frequently asked questions
Which sounds are free?
White, pink and brown noise, womb sound, heartbeat, shushing, the Brahms lullaby and rain — all eight are permanently free, together with the timer.
Do the sounds need downloading?
No. The noises are generated on the device and the other sounds ship with the app. It works offline from the first launch.
Can it play all night?
It can; there are no ads or connection drops to stop it. We still suggest setting the timer: it fades the sound out gently and keeps a loud setting from becoming an all-night habit.
Which sound is best for a newborn?
No sound works for every baby, and no study shows one noise colour beating another in infants. In the first weeks the womb sound and heartbeat are the most familiar, because they are the only sound environment your baby knows; white or pink noise covers a noisy home better. All of them are free in Agubu: play one low for a few nights, then another, and let the sleep log decide.
