Known for its steady and consistent hum, white noise creates a sound wall that can mask other stimulating disturbances. According to one study, people who listened to the equal frequency of white noise experienced a 38 percent reduction in the time it took them to fall asleep. Researchers also believe that white noise and nature-based sounds can help with anxiety reduction, nighttime agitation, and quantity of sleep—noting that obtrusive noises are a leading cause of sleep disorders. Running interference on harsh noises that can get in the way of a good night’s rest, white noise machines offer a serene sound environment, for healthy, high-quality sleep. Here are the best white noise machines on the market to help you sleep at night. Featuring adaptive sound technology that constantly monitors your environment, the machine adjusts to help reduce disturbing noises—a good option for people living in a big city. Thanks to two USB ports, you can also connect the machine to wired headphones or charge multiple devices from it. Because of its bulky design, it may not be a good option for people looking for something portable.

Sound

Whether it’s traditional white noise, nature sounds, or light music, people respond differently to specific sounds. So if you don’t know your preferences, it’s smart to find a customizable sound machine or one with a variety of sound options.

Volume

You want something that’s loud enough to block distracting noises, but soft enough to allow you to fall asleep and stay asleep. If you’re purchasing a machine for a child, the American Academy of Pediatrics advises parents to keep sound machines to no greater than 50 decibels and positioning them farther than 78 inches away from where your child is sleeping.

Looping

Looping means that the sound is repeated after a set amount of time—meaning it can sound like a pattern to some people. If the noise is looped rather than continuous, make sure it features a clean transition and nothing too jarring that could disturb your sleep cycle. You can also find non-looped options on some devices.

Versatility

If white noise is just one of the features you need, look into a sound machine that can do more—there are devices that also function as a night light, an alarm clock, radio, and more. Make sure all the extras you want or need are included.

One study saw a 38 percent reduction in the amount of time it took participants to fall asleep. Another study, which focused on using white machines to help infants fall asleep, found that 80 percent were asleep within five minutes compared to only 25 percent who fell asleep within five minutes without using a white noise machine. What’s more, researchers believe that white noise and soundscapes can help reduce anxiety and agitation. One potential drawback of using white noise machines is getting so used to sleeping with one that it makes it difficult to fall asleep without it. This could be a detriment when traveling or in the event you misplace or break your machine.
