Why a vacuum cleaner?
It sounds strange, but many parents notice that their baby calms down when the vacuum is running. A vacuum makes a loud, steady whoosh that covers every other sound, a bit like the constant background a baby hears before birth. The problem is that a real vacuum is loud, heavy to hold near a crib, and it has to be turned off at some point. A recording or a sound like this one lets you keep the effect without the machine.
Our vacuum is made live by your browser: a wide airflow centered on the middle frequencies, a light hiss on top, a low hum, and the whine of the motor with its harmonics, which wavers very slightly as a real motor does. It is steady, with no start and stop, and it loops without a seam.
Using it for a baby
A study in Pediatrics in 2014 measured infant sleep machines at full volume and found that all of them went above 50 decibels at 30 cm, the level recommended in hospital nurseries. A phone playing a vacuum sound can do the same, so the rules are simple: the phone across the room, a low volume, and a timer so the sound stops once the baby is asleep.

| Sound | Feel | When |
|---|---|---|
| Vacuum | Wide, full, strong | Calming a fussy baby |
| Hair dryer | Brighter, lighter | If the vacuum feels too heavy |
| Shushing | Rhythmic “shhh” | Crying, rocking |
| Fan | Soft, discreet | Once the baby is calm |
A good routine: start with the vacuum to calm the baby, then switch to a softer sound in the Home or Baby family once things settle. The change is smooth, with no gap.
Not only for babies
Adults use the vacuum sound too: to mask a snoring partner, noisy neighbors, or simply because they like a strong, even sound. It covers voices well because its energy sits in the middle range, where speech lives. Keep the volume low, especially for long sessions.
