The LectroFan Evo, an NBC Select Wellness Award winner, is a compact model with 10 fan sounds, 10 white, pink and brown noise variations and two ocean sounds. The machine offers precise volume control, a timer to automatically turn off sounds and an audio connector for headphones or a portable speaker. “I love this sound machine,” says editorial projects manager Rebecca Rodriguez, who often struggles with anxiety before bed. “I don’t really need anything fancy out of a sound machine and this one is simple, small and relaxing.“
Bonus features: nature sounds, headphone jack, multiple white noise variants
Sunrise alarm clocks, like the Hatch Restore 3, gradually emit light to gently encourage you out of your slumber instead of suddenly jolting you awake as standard alarm clocks do. This machine has a white, brown and pink noise setting and you can adjust the volume to your liking. “After using it for months, I can safely say that the Hatch Restore 3 (which the brand sent me to try) has altered my sleep for the better,” says Zoe Malin, NBC Select reporter. “I no longer dread waking up because I have the device’s beautiful lightscape and serene noise to look forward to.”
Bonus features: sunrise light, clock, nature sounds, instrumental music, podcast pairing, brown and pink noise
The Yogasleep Dohm Uno is a good option for those who want a simple, affordable, no-nonsense white noise machine. It comes with a one-year limited warranty and a single-dial mode that adjusts tone and volume to create a more personalized sound environment for sleep. I own two of these. I keep one outside my toddler’s door to block out household noises while she sleeps and the other in my bedroom to do the same. I love how simple it is to plug it in and flip the switch. There is no volume knob, but you can slightly lower the sound by turning the top to cover some of the speaker vents.
Bonus features: adjustable tone, available in a different color
This simple white noise machine from Adaptive Sound Technologies offers 10 fan sounds and 10 ambient noise variations (including white, pink and brown noise). It is powered by either AC or USB and you can adjust the volume with simple up and down buttons. Malin also uses this sound machine and says it’s ideal for anyone who wants a no-frills device that’s easy to use. “It has a built-in timer, which is great for anyone who doesn’t like to leave the sound machine on all night, and due to its small size, I can fit it in a suitcase or weekender bag while traveling,” she says. Since it retails for less than $50 and offers 20 different sounds, including brown and pink noise, it’s arguably the best value white noise machine on this list.
Bonus features: pink and brown noise, available in a different color
The smallest white noise machine on our list, this option has six different sounds to choose from. It can also be charged and used without a cord, making it easy to move around. “I had never used a sound machine before trying this product, but I was delighted by how easy it is to set up and put to use,” says Cory Fernandez, commerce editor at NBC Select. “It’s also super compact, lightweight and easy to bring with you when you travel.” It’s only around the circumference of a soda can and around half the height. Plus, since you can use it without a cord, you can bring it with you to a private workout or meditation session. You can also put it on a 10-, 30- or 60-minute timer, depending on what you plan on using it for.
Bonus features: nature sounds, meditation sounds, portability, 10 volume settings
You can use this sound machine when traveling or keep it on a bedside table, thanks to its slender shape. “I’ve owned this sound machine for almost six years and it’s still in perfect condition. I originally bought it for travel because I can’t sleep without a noise machine, and apps on my phone just weren’t cutting it,” says Malin, who notes she uses the above Hatch model at home and this one on the go. “This sound machine is battery operated, slim enough to throw in a suitcase without taking up too much room, and lets me customize the volume and sound I want to hear.” In addition to white noise, this machine plays rain, thunder, ocean and brook noises. You can choose between a timer of 15, 30 or 60 minutes, and since it has a flat bottom, you don’t have to worry about accidentally knocking it over in the middle of the night.
Bonus features: nature sounds
This small, square-shaped sound machine, which has a 4.5-star average rating from 62,301 reviews on Amazon, has more than 30 volume settings so you can find the exact one that fits your preferences. In addition to white, brown and pink noise, it makes sounds such as a running brook, birds, a campfire and waves. You can also set it on a timer for 60, 120, 180 and 240 minutes or let it run continuously while you sleep. The speaker faces upward and all of the controls are on the side.
Bonus features: nature sounds, 30+ volume settings, multi-hour timer
If you are shopping for a white noise machine, the experts we spoke to suggest keeping the following in mind:
White noise machines emit calming sounds to create a gentle, constant noise that many find soothing and helpful when trying to fall asleep. “The main way that white noise machines help with sleep is that they can mask other noises, absorbing wayward sounds that might otherwise disturb sleep — it’s like a blanket of sound that prevents other noises from getting through,” says Dr. Michael Grandner, who serves as director for both the Sleep and Health Research Program and the Behavioral Sleep Medicine Clinic. Here’s a breakdown of its main benefits:
Aside from white noise, sound machines sometimes distribute pink and brown noise, which differ in overall pitch frequency, according to Lynelle Schneeberg, PsyD, a fellow at American Academy of Sleep Medicine and an assistant professor at Yale School of Medicine. “White noise has a higher pitch than brown noise while brown noise reminds some people of ocean waves,” she says. “The sound a person chooses is really just a matter of personal preference.” White noise machines are more widely available than those that play pink or brown noise. Here’s a breakdown of the different types of noises:
