Getting a good night's sleep is easier said than done, and sometimes, we need a little extra help to get some shut-eye. While there are plenty of sleep aids on the market, some people want a natural, non-medicated method for getting a healthy night's rest. If you have trouble falling asleep or are easily awakened during the night, many sleep specialists recommend a sleep machine.

White noise is one of the most popular sounds featured in sound machines. It's similar to that of a box fan or air conditioner, and studies have shown that using white noise throughout the night can result in a longer, more restful night's sleep. But if white noise doesn't do it for you, there are plenty of other equally peaceful options available.

Whether you are a white noise fanatic or more of a natural sound kind of sleeper, you'll be able to find a sleep machine that fits your specific needs here.

What to Look for in a Sound Machine for Sleep


A peaceful, subtle, box fan sound is the ideal volume when it comes to sound machines. If you're a particularly light sleeper, you may want to take volume level into consideration when looking for a sound machine. While most offer a range of volumes, be prepared to give your machine a test run.

Sound Effects:

Many sound machines on the market offer white noise as their primary feature, which is a great middle-ground when it comes to sleep machine sounds. Others offer a wide variety of sounds, such as the ocean, rain, and forest sounds. Sound machines made particularly for babies often feature lullabies that play on a loop throughout the night. If you're partial to one particular sound effect, be sure to double-check the description to make sure it includes your preferred noise before purchasing your sound machine.

Additional Features:

In addition to playing sleep-friendly sounds, some sound machines do double-duty work. Particular models feature alarm clocks and built-in thermometers, so you get a little more bang for your buck. Take a look at all of the features each model has to offer before buying.

“In choosing a sound machine, it’s nice to have options and controls. Lower volume, good sound quality, and a range of sounds that are pleasing—and boring—are helpful.” Alex Dimitriu, MD, double board-certified in Psychiatry and Sleep Medicine

Frequently Asked Questions

  • When should you stop using a sound machine for your baby?

    Sound machines can be helpful tools to aid babies (particularly newborns) fall asleep and stay asleep. 

    “Over nine months of pregnancy, babies get used to noisy and snug environments,” explains Dr. Alex Dimitriu, a double board-certified psychiatrist and sleep doctor. “This is why babies like being swaddled, and also why babies like some gentle background sounds as opposed to complete silence.” 

    Around the age of three to four months, “the calming reflex will gradually disappear,” says Dr. Harvey Karp, pediatrician, author of “Happiest Baby on the Block,” and co-founder of SNOO. “But by then, your infant will be aware of the connection between white noise and the pleasure of sleep.” So, white noise machines can continue being helpful to parents. 

  • Can sound machines cause hearing problems?

    Any prolonged or very loud noise can damage hearing—and research has shown that some sound machines are too loud, especially for infants. As a result, it’s recommended sound be kept to 50 decibels around infants to prevent hearing issues. “Quieter is always a safer option,” Bates says. 

    Of course, if your baby is crying and can’t hear the sound machine, it’s okay to turn it up temporarily. “The sound needed to turn on the calming reflex when a baby is crying is a rough, rumbly noise that’s as loud as he's crying,” explains Dr. Karp. But “once your baby is calm, lower the level of your white noise to about the loudness of a shower”—or even less if you can get away with it. 

  • Can you become dependent on sound machines for sleeping?

    Yes, it is possible for both adults and children to get so used to their sound machine, says Dr. Dimitriu, that it leads to a “mild dependence on sound machines that forms over time, much as how people get used to their bedroom or favorite blanket.” This could make it more difficult for you to fall asleep somewhere that’s quieter than you’re used to—like hotel rooms, different houses, etc. 

    However, “it isn’t a bad form of addiction,” says Bates.
