The best sound machines
Steady, soothing sound in the background, so a slammed door or a passing truck is less likely to wake a baby or a light sleeper.

The top 5 at a glance
A sound machine sits on a nightstand or a nursery shelf and plays one constant sound while someone sleeps, so sudden noises stand out less against it. White noise is the classic hiss, and brown and pink noise are deeper and softer. Most machines play recordings through a small speaker; a few spin a real fan inside instead.
They aren’t only for babies: plenty of adults use one to sleep through traffic or a snoring partner, or to keep office conversations private. Every machine here plugs in, so there’s no battery to run down overnight. In a nursery, keep the volume low and the machine well away from the crib rather than beside the baby’s head.
What matters
- A timer for naps, or the choice to play all night.
- A night light soft enough for feedings, if it’s for a nursery.
- A fan sound as well as plain white noise.
#1BrownNoise Sound Machine with Night Light (30 sounds)
$20–$30
Brown, pink and white noise, a loud and a soft fan, lullabies, rain and waves: 30 sounds, as many as any machine here, and the only night light on the list with a choice of colours. A nursery or a grown-up’s bedroom gets all it needs without paying for a Bluetooth speaker, an alarm clock or a real fan.
What owners say: Owners say it helps babies fall asleep and works just as well for grown-ups, with lots of sounds to pick from and a size that packs into a suitcase. Sound quality is where opinions differ.
A closer look: If plain white noise sounds too hissy, try brown next, then the fans. The light switches on and off apart from the sound, so a dim colour can stay on for night feedings while the sound plays, or go dark altogether in an adult’s bedroom.
- Brown, pink and white noise
- Loud and soft fan sounds
- Light has its own button
Best for: Sleep for babies and grown-ups
- Power
- USB cable (adapter not stated)
- Sounds
- 30, incl. fan and nature
- Night light
- 12 colours, 10 levels
- Timer
- 1, 2, 3 or 4 hrs, or all night
- Good to know
- Remembers the last sound and volume
#2SNOOZ Original White Noise Machine (real fan)
$100–$150
A real fan spins inside, so the sound is moving air rather than a recording, with no loop to notice. Turning the shell takes it from a light whoosh to a low hum, the touch controls give ten volume levels, and the free app works it from bed or switches it on and off at set times.
What owners say: Owners love the sound itself and how far the volume and tone adjust, from very low to very loud, and say it blocks a lot of noise. Price is the one point that splits them.
A closer look: SNOOZ suggests setting it between the bed and the noise, on a nightstand or dresser, about 1 to 1.8 m (3 to 6 ft) from your head. It makes one sound only and has no night light, so a nursery that wants lullabies or a glow is better served by the others here.
- Shell turns to change tone
- Ten volume levels
- App works it from bed
Best for: Light sleepers who like a fan
- Power
- Wall adapter, 1.8 m (6 ft) cord
- Sounds
- 1, a fan
- Night light
- None
- Timer
- On and off times set in app
- Good to know
- Real fan, not a recording
#3Yogasleep Duet Sound Machine with Night Light and Wireless Speaker
$50–$75
A sound machine, a warm night light and a wireless speaker in one: 30 non-looping sounds from white, pink and brown noise to eight lullabies, or a podcast streamed from a phone at bedtime. Yogasleep began as Marpac, whose fan-based machine of 1962 is often credited as the first white noise machine for the home.
What owners say: Owners rate the sound and the warm glow, which turns down from bright to a very low light, and say the speaker works well. Nothing comes up as a recurring complaint.
Heads up: Yogasleep says the USB cable needs a 5V, 1A wall adapter that isn’t in the box, so have a phone charger plug ready.
A closer look: Pair a phone once with the Wireless button and the Duet plays a sleep story or a playlist through its own speaker; it isn’t made for phone calls. A press of the light button turns the amber glow on or off, and holding it down sets how bright it is.
- Sounds play without looping
- One-button phone pairing
Best for: Streaming your own sleep sounds
- Power
- USB cable, adapter not included
- Sounds
- 30, incl. fan and nature
- Night light
- Warm amber, dimmable
- Timer
- 45 min, 90 min or 8 hrs, or all night
- Good to know
- Bluetooth speaker for your phone
#4Dreamegg D1+ Sound Machine with Alarm Clock
$50–$75
Dreamegg’s Classic D1 design with an alarm clock built in, for a bedside where one machine plays white noise at night and wakes you in the morning. Its 29 sounds take in white noise, fans, lullabies and nature tracks, and the clock’s display dims for a dark room.
What owners say: Children sleep well through naps with it on, owners report, and they praise the range of sounds, the night light, the volume control and its looks.
A closer look: Six nature tones wake you gently and a 9-minute snooze buys a little more time, so it can take the place of a separate alarm clock on the nightstand. Set the sleep timer to 30, 60 or 90 minutes and the sound stops on its own, or leave it playing all night.
- Gentle nature alarm tones
- Clock display dims down
Best for: Replacing the bedside alarm clock
- Power
- Corded (adapter not stated)
- Sounds
- 29, incl. fan and nature
- Night light
- Warm, controlled separately
- Timer
- 30, 60 or 90 min, or all night
- Good to know
- Alarm clock with snooze
#5Dreamegg D1 Sound Machine with Night Light
$30–$50
A plain white nursery machine, Dreamegg’s Classic D1, with 24 sounds: seven kinds of white noise, seven fan sounds and ten nature and nursery tracks, a fetal tone and a lullaby among them. The warm night light is optional, and bright enough for a night feeding.
What owners say: It helps owners sleep, they say, with a good spread of sounds and a light that can stay off, and it’s simple to work, though sound quality, reliability and noise control get a mixed reception.
A closer look: The USB cable lets a laptop or a power bank run it in a hotel room as well as from the wall. When the timer runs out, the sound fades away rather than cutting off suddenly.
- Fetal tone and lullaby tracks
- Sound fades as timer ends
Best for: Nurseries and hotel rooms
- Power
- Adapter or USB, both in box
- Sounds
- 24, incl. fan and nature
- Night light
- Warm, on or off
- Timer
- 30, 60 or 90 min, or all night
- Good to know
- Remembers all its settings
