Since being featured on Shark Tank in 2016, Hatch, previously known as Hatch Baby, has become one of the most well-reviewed manufacturers of white noise and light machines. The Hatch Restore is their first offering aimed at adults and has a rich array of impressive features that our testing team found to be both practical and effective.

The Restore has a library of soundscapes, including both white noise and natural sounds, such as water. While these can be used individually like a traditional white noise machine, owners can also use them as part of the Restore's easily programmable sleep routines.

Sleepers can set a multi-step routine on the easy-to-use app. Steps can include soundscapes, meditations, sleep stories, and light adjustments, all of which are intended to gently guide users to sleep. The Restore also has a programmable sunrise alarm to wake sleepers up with sun-mimicking light.

While some soundscapes are bundled with the machine, Hatch's full library of meditations, sleep stories, and soundscapes requires a subscription after the free six-month trial finishes. Hatch stands behind the Restore with a 1-year limited warranty against manufacturer's defects, and customers can return their Restore in its original packaging within 60 days for a refund of the purchase price.

More than just a white noise machine, the Loftie Clock features a two-phase alarm that is customizable. The initial alarm sound is designed to gently coax sleepers out of slumber, while the second alarm is loud enough to wake the soundest sleeper. As many as 30 alarms can be set at a time.

Loftie Clock's white noise and nature sounds are designed to induce sleep. Sound content can be programmed to play for a specific duration of time or for the entire night.

The Sweet Zzz White Noise Machine is a great option for shoppers on a budget. While the device has an extensive library with more than two dozen programs and additional features to enhance your sleep experience, its price-point is quite reasonable compared to many competing models.

In addition to white noise, the machine allows you to play pink noise, which combines low- and high-frequency tones to create a sound that is both soothing and intense. A brown noise program is also available for those who enjoy a stronger sound that relies solely on low frequencies. The library includes a wide selection of ambient sounds as well, including rain, fan noise, ocean waves, and singing birds. Each program is designed for seamless playback, so disruptive looping won't be an issue.

The battery can perform for up to 12 hours before you'll need to recharge the device. You can also program the machine to automatically shut off after 30, 60, or 90 minutes.

Yogasleep Classic Natural Sound Machine

Noise Type: Non-looping pink noise playback

Features: Adjustable (2-speed), 1-year warranty

Who it's best for:

SleepFoundation.org readers get 20% off Dohm Classic. Coupon automatically applied

While multiple sounds, features, and settings may appeal to some people, others may prefer a white noise machine that is easy-to-use and has a minimalist appearance. The Yogasleep Dohm Classic Natural Sound Machine is a fan-generated white noise machine that fulfills these requirements, offering easy manual adjustment despite only having a single switch.

To turn on the device, users flip the switch to either the low or high volume setting. Once this is set, the sound of the fan can be adjusted by turning the top of the machine. This changes the pitch and tone of the white noise, allowing for brown and pink noise depending on the setting. Some people prefer fan-generated white noise to pre-recorded tracks, as there is no looping and fans have a unique, appealing rhythm. However, moving parts do sometimes break down and create additional, less soothing noises.

Sleep trials are unusual for white noise machines, but Yogasleep allows customers to return their Dohm Classic within 101 nights if they aren't satisfied. The company also offers a 1-year limited warranty which covers manufacturing or workmanship flaws.

What is a White Noise Machine?

"White noise machine" is a catch-all term that can describe a wide range of models, ranging from those that create white through mechanical means, such as with a fan, to those that play both white noise and soothing tracks, like nature sounds or music. The connection among these different machines is that all are meant to offer sounds that drown out unwanted noises, also known as noise pollution, while relaxing or focusing the listener. Because of this goal, many white noise machines actually produce the more calming pink or brown range of noise.

People use white noise machines for several distinct reasons, including studying or working, meditating, or reducing the perception of tinnitus. However, possibly the most popular use is to help people fall or stay asleep.

Research shows that white noise can help improve sleep, particularly in noisy environments. Babies also show a good response to white noise, with one study finding that 80% of very young infants fell asleep within five minutes when exposed to white noise, versus only 25% of those without white noise. There is also some evidence that white noise may calm infants who suffer from colic.

Of course, what aids or hinders sleep is always highly personal. White noise machines can help many people achieve better sleep, but they do not work for everyone. Some people, regardless of age, respond poorly to white noise machines. Even those who enjoy white noise or nature sounds may be very particular about what sounds they find soothing, and the wrong frequency of white noise may quickly become aggravating. If this is true for you, it's worth investing in a model that allows you to customize the pitch and tone of the noise.

How to Choose a White Noise Machine

Choosing a white noise machine can feel difficult, particularly with the wide range of varieties on the market. This guide will walk you through what you need to know before making a decision, including both critical attributes like volume control and additional functions like alarms and lights.

What to Consider When Purchasing a White Noise Machine

By considering these eight important factors, it's easier to decide what features are important to you and what machine might work best for your needs.

Sound Options
White noise machines either play recorded sounds or mechanically generate white noise, usually with a fan. Choosing between these options is largely a matter of personal preference, though people interested in other sounds (such as waves or birdsong) will most likely prefer a machine with recorded sounds for a wider variety of options.

Volume Options
The volume of a white noise machine should be loud enough to cover noise pollution but not so loud as to interrupt sleep or damage hearing. This is particularly important for children, as studies have shown that excessively loud white noise can be especially harmful to them. Most white noise machines have a wide range of volume options and sensitive controls, though some lower-end or minimalist models may only allow you to choose between two or three volume settings.

Value
There are white noise machines available at virtually every price point, though the majority cost less than $100. Lower-priced models tend to have fewer features, while those at the higher end usually have lights, alarms, and/or other additional functions. These can offer a good value if you would otherwise buy a separate machine for these functions, but lower-priced white noise machines work well for those who are only interested in soothing sounds.

Smart Features
Just like so many other electronics, many white noise machines now offer smart features, like integration with apps or home networks. These models tend to also have other functions, such as lights or routines, that make app connectivity useful. For most situations, this is a non-essential feature, but parents may appreciate having this kind of control over their child's white noise machine.

Display
Light from a white noise machine can disrupt sleep, so it's crucial to choose a model with either minimal light or with lights that can be dimmed or turned off. Many well-made machines have no lights at all, while others have a clock screen or even function as a night light. The latter variety usually allows for more in-depth control, allowing owners to change the color and intensity of the light.

Timers
Some people prefer to have their white noise machine running all night, while others like to have it turn off automatically at a certain point. Most white noise machines have some kind of timing function, but this can range from preset automatic shut-offs to programmable on and off timers set through an app.

Portability
If you plan to take your white noise machine traveling, or even move it from room to room on a regular basis, it's worth considering its portability. While many white noise machines are quite small, particularly those without additional lighting features, they may require a plug-in outlet or weigh more than one might expect. Travel-friendly models, however, are likely to be lightweight and offer features like USB charging.

Other Features
As the white noise machine market is fairly crowded, many models try to set themselves apart with additional features. Alarms and lighting are both common, as are USB ports for charging your electronics. Headphone jacks are rarer but highly valued by those who share a room with a partner not interested in white noise or other sleep sounds. Depending on your needs, these features may be necessary, useful but not essential, or entirely unwanted.

Frequently Asked Questions About White Noise Machines

What Does "White Noise" Mean?

White noise contains all audible frequencies, which coalesce into what we perceive as a humming sound. Common everyday sources of white noise include fans, television static, and air conditioners. So-called "white" noise machines often produce pink or brown noises, which are like white noise with more intensity at the lower frequencies. These sounds are usually more calming, and many stereotypically relaxing sounds — including rain and waves — tend to be in this range. Blue, violet, and grey noises also exist but are less useful for relaxation.

What Type of Background Noise is Best for Sleeping?

White, pink, and brown noises are all suitable for sleep, as are natural sounds that fall into these ranges. Since these sounds contain all audible frequencies, they "fill in" the gaps between unwanted noises that may otherwise wake us up.

Can White Noise Be Harmful?

While white noise is generally thought to be safe, there are some risks and considerations to keep in mind. Any prolonged noise over 70 decibels — the level of a washing machine when standing next to it — can damage hearing, so it's crucial to keep white noise machines at a lower volume than this. There is also a small amount of evidence that regular white noise as a part of tinnitus therapy may cause long-term issues for those with tinnitus, but this is unlikely to be a concern for most people using white noise machines as part of their sleep routine.

Nonetheless, if you have concerns or underlying health issues, it's always best to talk with your doctor before starting a new routine.

Are White Noise Machines Safe for Infants and Children?

White noise machines appear to be safe for children, regardless of age, so long as they are operated properly. One study has shown that many models are capable of being loud enough to damage an infant's hearing, but the study's authors were clear that the volume, machine position, and duration were all important factors in reducing this risk. They recommended placing the white noise machine some distance from the crib, playing it at a comfortable volume, and not using it over extended periods.

Is White Noise Helpful for Focus?

White noise aids focus by blocking out noise pollution. Since it "fills in" the space between outside sounds, it thereby dampens them. For people who work in loud spaces or are easily distracted, this can make a significant difference in their focus. There are also some indications that white noise may affect perception and cognition depending on the timing and task at hand.
