How to Choose a White Noise Machine for Better Sleep
Neighbors, traffic, a snoring partner, or a house that creaks at night: a steady background sound can make those noises easier to ignore. A white noise machine is a simple way to get one. This guide explains what to look for, which sound types are available, and when you may not need a dedicated machine at all.

What a white noise machine does
A white noise machine plays a steady, repeating sound at a volume you choose. The idea is that a constant sound makes sudden noises, like a car door or a barking dog, less noticeable. Many people find this helpful; it doesn't work for everyone, and it isn't a treatment for any sleep problem. If you regularly struggle with sleep, a doctor is the right person to ask.
Who it suits
It tends to suit light sleepers, people who live near traffic or in apartments with shared walls, and people who travel and sleep in unfamiliar rooms. It's less useful if your main problem is light rather than noise, or if you find any background sound distracting.
Sound types explained
- White noise. An even hiss across all pitches, like static or a steady shower. Good for covering a wide range of sounds.
- Pink noise. Softer and a little deeper than white noise, closer to steady rainfall.
- Brown noise. Deeper again, like a low rumble or distant waterfall. Some people find it less sharp.
- Nature and fan sounds. Rain, ocean waves, or a fan. Pleasant, but check that they don't loop in a way you can hear.
It's worth choosing a machine with a few options, since the sound you like is personal. It can take a night or two to find the one that works for you.
Features that matter
- Natural-sounding, non-looping audio. Some machines repeat a short recording that you can start to notice. Look for reviews or product details that mention smooth, continuous sound.
- Volume range and control. You want it quiet enough to be comfortable and loud enough to cover the noise. Fine volume control helps.
- Timer and all-night mode. A timer is handy if you only want it while you fall asleep. An all-night mode is better if noise wakes you later.
- Speaker quality. Small speakers can sound thin or buzzy at higher volume. A fuller sound is easier to tune out.
- Memory. Check that it remembers your last sound and volume after a power cut or when you turn it off and on.
- Power and portability. Battery or USB power makes a machine easy to take on trips. A plug-in model is fine if it stays on your nightstand.
- Night light and extras. Some have a dim light, a clock, or Bluetooth. Pay extra only for features you will use.
Machine, fan, or phone app?
| Option | Suits | Keep in mind |
|---|---|---|
| Dedicated machine | People who want a reliable, simple sound every night | One more device and cable on the nightstand |
| Fan | People who also want airflow, or want to try before buying anything | Not much sound variety, and airflow may not suit every season |
| Phone app or smart speaker | Travelers, or anyone who wants to test whether sound helps | Phone notifications and battery drain can get in the way |

Yogasleep Dohm Classic
Best for: People who dislike recorded sounds that loop
Why it's on the list: It makes its sound with a real fan inside, so there's no recording to repeat. It's a long-time favorite in this category.
Keep in mind: It offers only a couple of tones, not a library of sounds.
Tuft & Needle White Noise Machine
Best for: People dealing with loud neighbors or street noise
Why it's on the list: Sleepopolis picked it for loud neighbors and noted its real-fan sound.
Keep in mind: Check the current listing for its sound options and timer features.
Hatch Restore 3
Best for: People who want white noise and a sunrise alarm in one device
Why it's on the list: Sleepopolis chose it as the best white noise machine overall, with a wide range of sound types.
Keep in mind: It's pricier than a simple sound machine, and some features may need the app or a subscription. It's the best value if you'd also use the sunrise light, covered in our sunrise alarm clock guide.
Setting it up well
- Keep the volume at a comfortable, moderate level. It should cover noise, not compete with it.
- Place it a little way from the bed, ideally between you and the source of the noise, such as a door or window.
- Give it a week before deciding. It can take a few nights to get used to sleeping with a background sound.
- If you use one in a baby's room, follow the manufacturer's guidance on distance and volume, and ask your pediatrician if you're unsure.
Common questions
Does white noise really help you sleep?
Many people find it makes disruptive noises less noticeable, but results vary. Some people prefer silence.
Should it run all night?
It depends on what wakes you. If noise disturbs you in the early morning, all-night sound may help. If you only need help falling asleep, a timer is enough.
White, pink, or brown noise: which is best?
There's no single best choice. Try a few. Deeper sounds feel softer to some people, while others prefer the sharper cover of white noise.
Do I need Wi-Fi or an app?
No. Many good machines use simple buttons or a dial. Apps add options, but they also add setup.
The short version
Choose a machine with several sound types, smooth non-looping audio, fine volume control, and a timer. Keep the volume moderate, give it a week, and skip extras you won't use.
