Quick answer
Yes, a sound machine can help babies sleep by providing steady, womb-like noise that masks household sounds and becomes part of a consistent sleep cue. It is not a magic switch, and it will not replace a safe sleep space or a predictable routine. Keep the volume low, place the machine away from the crib, and choose a model with continuous, non-looping sound such as the Dohm or Hushh 2.

How white noise actually works for baby sleep
Babies spend months hearing a constant rush of sound in the womb, so a steady fan-based hum can feel familiar rather than startling. The practical benefit is masking: a sound machine covers the sudden noises that wake a baby, like a door closing, a dog barking, or an older sibling talking in the next room. The Dohm produces fan-based white noise the way it was meant to sound, with a real fan inside creating continuous, natural noise that never repeats or skips, so your baby's brain stops noticing it. That matters because looping digital tracks can develop an audible pattern that some babies begin to anticipate. Two speed options and a tone dial let you customize volume and pitch for your space, which helps when you move from a noisy living room to a quieter nursery.
The volume and placement questions parents ask most
There is no universal decibel number that fits every room, but the practical rule is simple: the sound should be no louder than a soft shower, and you should be able to speak at a normal volume over it without raising your voice. Place the machine across the room rather than in or on the crib, and avoid pointing it directly at your baby's head. If you are using a portable model while traveling, check the volume each time you set it up, because a small hotel room, a tent, or a car changes how loud the same setting feels. A rechargeable, drop-tested option such as the Hushh 2 is built for that reality of traveling with a baby, so you are not hunting for an outlet in the dark.
When a sound machine is not the answer
A sound machine supports sleep, but it does not create it. If your baby is hungry, uncomfortable, teething, or overtired, noise will not fix those needs. It also will not make an unsafe sleep surface safe, and it should never be used to drown out the sound of a baby who is genuinely distressed. Think of it as one layer in a routine that includes a consistent bedtime, a dark room, and a safe sleep space. If you are already doing those things and sleep is still rough, the sound machine is not the problem to solve next.
Myths vs. facts: sound machines and baby sleep
- Myth: A sound machine will train your baby to need noise to sleep.: A steady sound is a sleep cue, not a dependency. Babies already rely on routines like a bath, a feed, or a dark room. A sound machine is simply another consistent signal that sleep is coming, and you can fade the volume over time if you want to. Verdict: Myth. It is a cue, not a crutch.
- Myth: Any white noise app on your phone works just as well.: Phone apps can loop, skip, or stop when a notification arrives, and a phone in the room invites scrolling and light. A dedicated machine like the Dohm uses a real fan for continuous, natural noise that never repeats or skips, so it does not develop an audible pattern. Verdict: Mostly myth. Dedicated machines are more reliable for overnight use.
- Myth: If some noise helps, more noise helps more.: Louder is not better. Keep the volume at a soft-shower level, place the machine across the room from the crib, and check the setting whenever you change rooms. A portable machine such as the rechargeable Hushh 2 makes it easy to keep the same low setting on the road. Verdict: Myth. Low and steady beats loud.
Sound machines that fit the facts
- Dohm: The Dohm produces fan-based white noise with a real fan inside, creating continuous, natural noise that never repeats or skips. It has two speed options and a tone dial to customize volume and pitch. Continuous, non-looping sound is easier for a baby's brain to tune out, and the tone dial lets you adjust pitch to suit a nursery, hotel room, or shared space.
- Hushh 2: Hushh 2 is built for the reality of traveling with a baby, drop-tested and rechargeable. A rechargeable, durable machine removes the outlet hunt and the worry about knocks and drops when you are room-sharing away from home.
- Dohm Classic: Dohm Classic is the original fan-based white noise machine, assembled in the USA and backed by over 60 years of sound science. A long-established design is a low-risk choice if you want a simple, proven white noise source for a nursery.
