White noise machines may help promote restful sleep, improve cognitive ability, and help children with attention deficit hyperactivity disorder (ADHD) focus on tasks.
One 2016 study into the effect of white noise on patients in coronary care found that white noise machines helped the participants block out environmental noise. White noise also reduced the amount of time it took for them to fall asleep and increased the quality and length of sleep.
A 2017 study found that the use of white noise in learning exercises helped adults with no health or cognitive conditions recall and retain new words when compared with adults who did not use a white noise machine. This suggests that white noise machines may improve cognitive performance.
Also, a small study from 2020 found that white noise at 75 decibels helped elementary school students with ADHD focus in class and promoted better sleeping practices at home — even if the white noise only played during class times.
The sections below will list six of the best white noise machines and what their benefits and drawbacks are.

Although white noise can be beneficial, people should be careful about the volume of the white noise coming from their machine, particularly if they are using it to soothe infants.
A 2014 study by the American Academy of Pediatrics (AAP) found that white noise machines regularly emit noise at a high enough level to cause hearing damage in infants. This level of noise may also affect aspects of development, such as speech and language development.
As a result, the AAP recommend that parents and caregivers use white noise machines:
White noise machines with sleep timers can help people automatically switch off the noise once an infant falls asleep.
Adults should not increase the volume of a white noise machine to more than 70 decibels. Any sound over 85 decibels can damage hearing over time.
In addition to a white noise machine, a person can try other methods for inducing sleep, such as:
If a person cannot sleep due to another member of the household snoring, they may find earplugs helpful. People can reduce the chance of snoring by avoiding alcohol before bed and sleeping on their back. Sleeping on the side or with the head slightly elevated may also help.
White noise machines can help improve sleep quality and improve focus in both adults and children. There are a number of white noise machines available, with a variety of additional features, including sleep timers, nature sounds, and portability.
However, although white noise machines can be beneficial, they may cause hearing damage if a person uses them for long periods of time. They can also exceed the volume limits that experts recommend for infants. Therefore, use white noise machines at a low volume and place the device far away from the bed or crib.
