The best sound machines for sleep work by generating a soothing sounds and white noise. Nature sounds are the most common, and include rain, thunder, ocean noise and bird song. You can buy sound machines for babies, kids and adults, and many double as white noise machines to mask the sound of others in a busy office. Sound machines can also help mask tinnitus to an extent.

White noise machines and nature sound machines are simple to use, and are usually mains powered, though some can also be battery powered (good for travel). HoMedics sound machines are among the best-known – HoMedics also makes some of the best sunrise alarm clocks – but the Marpac Dohm Classic is our top pick. It offers just one type of noise, which is unusual for a sound machine, but it’s very effective for sleep.

When choosing the best sound machine for sleep, think about which sounds relax you the most. After all, there’s zero point buying a pure white noise machine if you can’t stand the sound of fans. Next, think about functionality. Does your sound machine need to double as an alarm clock or night light?

You’ll find plenty of sound machines for babies too, as these are brilliant devices for helping little ones settle more easily. Experts recommend placing the machine at least 30cm from your baby, and starting off with a quiet volume. We’ve been using sound machines for years and, as light sleepers we can honestly say that aside from getting the best mattress online and some great pillows for sleeping, a sound machine is a true sleep essential.

Only nature sounds

Different sounds affect the brain in different ways – loud sounds such as car alarms, can put the brain in a state of high alert, while natural sounds, such as flowing water are more calming because they are not perceived as a threat. These natural water sounds are also easier to ignore, while masking other more distracting sounds, even at louder volumes.

The Big Red Rooster Sound Machine might only have a small selection of sounds but they will have broad appeal with natural water sounds that include standard rain, gentle ocean, a pleasant brook (ideal for meditation), and a favorite with many: thunder. There is also a white noise and  ‘summer night’ option with crickets. 

The Big Red Rooster Sound Machine is easy to use and has a minimalist design with clearly laid-out buttons on top. It is lightweight and small enough for travel, with power that comes courtesy of mains, USB or battery. There is also a sleep timer for 15-60 minutes, or you can let it play constantly.

Recreates a 'shushing' sound

Reasons to avoid

-
Only produces one noise

Short timers

It’s no secret that getting little ones to settle can be hard work, but natural shushing noises have proved to be effective for helping newborn babies calm down during a crying spell. 

Husband-and-wife team Chad and Katie Zunker devised the Baby Shusher with the concept of ‘rhythmic shushing’ in mind, after they realized how difficult it was to sustain the shushing themselves with their own newborn.

The Baby Shusher, which recreates a parent's 'shushing', is consistently touted as a ‘miracle worker’ by parents, and the best sound machine for babies. This award-winning, portable noise generator helps babies settle at home in the crib, when they're in the car, or out and about in the stroller.

The Baby Shusher is powered by two AA batteries and has two timer options for 15 to 30 minutes, as well as an adjustable volume. It's well made too, and exceeds safety standards by being BPA, latex, lead and phthalate-free.

Best sound machines FAQ

What is a sound machine and how do they work? 

Sound machines are devices that output natural noises such as lapping waves, rustling trees, or mechanical sounds like fans, air con and hair dryers. They also produce ‘white noise’, which has a frequency range of 20 to 20,000hz, as heard in radio and TV static. 

Many people are comforted by these sounds, and they are particularly effective at helping babies to settle. Sound machines provide a non-distracting consistent background noise to make other more intrusive noises less noticeable to you. 

This is ideal if you have a partner who snores, you live in a noisy neighborhood, or you're distracted by the noise of others during work. Sound machines are also effective when it comes to masking tinnitus and can provide a degree of relief.

White noise machines vary in style, with many offering more than 30 sounds to choose from. They mainly play digitally recreated sounds, some of which are on a loop. However, sound machines like the Dohm Classic use an internal fan to recreate noise, without the need for having an actual fan in the room.

Do sound machines help you sleep?

Many people use sound machines to help them and younger members of the family fall asleep. As well as providing a less distracting environment in the bedroom, white noise machines are great as part of an evening bedtime ritual. That's because the sounds act as a trigger for your brain to relax and fall asleep quicker. We cover relaxation before bed in our feature looking at why is sleep important for humans.

Another huge benefit of sleep machines is that they are portable, so you can pack one for travel and holidays. This is handy if you're sleeping in a hotel with potentially noisy guests. 

When choosing a sound machine for sleep, a timer is useful as it will switch off the device automatically after a set period of time. Some people prefer to leave their white noise machine running throughout the night. Reasons include masking the sound of a snoring sleep, traffic on the road, or dogs barking outside.

A lack of interruptions to your sleep will contribute to a more restful night, which will improve your mood and brain functionality the following day. If broken sleep is affecting your mental health, check out our guide to the best light therapy lamps, designed to alleviate symptoms of Seasonal Affective Disorder, including low mood.


How long should you use a sound machine with a baby for?

Many parents rely on sound machines to help little ones settle and fall asleep quickly. But these devices might not work with every baby. It's recommended that white noise machines should be placed as far away from the crib as possible (at least 30cm away from baby’s head) and played at a volume that does not exceed 50db. This is the standard set in hospital nurseries. 

50db is approximately the sound of ‘moderate rainfall’ (as a comparison, normal conversation is approximately 60db). Start off as quietly as possible until you find a volume that suits your baby. Sound machines with timers are handy, as you can set them to automatically switch off after a specific period of time.

Typically, parents might use a white noise machine until their child is around 18 months, or when the child has learned to sleep fall asleep on their own. Every baby is different though, so this is just general guidance.

Sound machines vs white noise machines: Is there a difference?

Yes. White noise is the term for the sound produced by all frequencies from 20 to 20,000hz at the same amplitude. This includes the sound given produced by fans, air con, or old-fashioned TV and radio static. 

White noise is ideal for creating background noise to mask other distracting sounds at bedtime or in noisy offices. Play around with volume, distance and duration until you find a combination that works for you.

Sound machines offer other types of noises in addition to white noise. This includes ‘pink noise’, which is stronger at the lower frequencies and includes rustling leaves. Sound machines also produce ‘brown noise’, which accentuates more at the very lowest frequencies and is particularly ideal for noisy environments. 

Brown noise includes sounds such as waterfalls and thunder. The very best sound machines also include musical extras and nature sounds, such as chirping birds and crickets. 


Who would benefit from a sound machine? 

People working in noisy environments
Researchers from the University of British Columbia conducted research on the effects of noise masking with white noise machines in a noisy office environment. Their conclusion: “Masked noise subjects performed better than those in the unmasked condition on both complexity and a simple attention task.” 

Tinnitus Sufferers
The American Tinnitus Association lists sound therapy as a "masking and distraction solution for Tinnitus symptoms". There are multiple sound therapy options, including sleep apps, but a traditional sound machine with a wide range of sound profiles is less invasive and easier to operate. 

The ATA suggests that, “The noise generated by sound machines can partially or fully mask a patient’s perception of tinnitus, providing relaxation and temporary respite from the condition.” Sound machines don’t cure the condition, but they significantly reduce the perceived ringing and help people with tinnitus fall asleep easier.

Irregular work schedule
Employees who work a rotating schedule or night shifts often have trouble aligning their body’s internal clock with external distractions. External stimuli, such as light and noise, send signals to the brain that trigger natural reactions like the release of sleep-inducing hormones and changes in body temperature. 

A sound machine can help regulate your internal clock by masking external noises. We recommend sound machines with a continuous play feature if you need to mask external noises the entire time you sleep.


Best sound machines: What to look for

Sleep timer
Sound machines are designed to help you fall asleep, but once you are asleep, timers automatically turn the sound off after a period of time. The best sound machines give you multiple timer options. 

Some have options ranging from 15-90 minutes, but some last up to seven hours. We recommend using the continuous setting for masking noise, rather than allowing the machine to turn off while you’re asleep, otherwise you may wake up again.

Headphone output
When you plug headphones into a sound machine that has this output selection, the speaker turns off. That is a helpful feature if you have a bedmate who doesn’t share the same need for calming noises. It can also be helpful for someone who works in a noisy environment and doesn’t want to bother other employees.

Battery backup
All the sound machines we tested plug into a wall socket, but some use batteries as a secondary power source. Battery operation is handy for periods of travel use, especially somewhere that doesn’t have an available wall socket, like a campsite.
