Five of the six machines we included are under $100, and one of them is free.

You can either purchase an actual machine (some have more bells and whistles than others), or you can try free white noise applications on your smartphone. When it comes to white noise machines, you have options depending on your budget. A couple of machines also have variety in frequencies, sound types, and additional features. But we also included a classic, no-frills option if you’re just starting out with white noise machines. We looked at machines that work for various scenarios, such as for travel or children. Here, we’ve included six white noise machines, each with an element that’s a little different than the others.

"It's essential that we look at what is disrupting our sleep, whether that's a racing mind, the inability to switch off at night, or a misaligned circadian rhythm, for example, and then address that." "I would add that noise machines, or other sleep gadgets for that matter, are not a silver bullet for all sleep issues," says Mikhail.
Users also need to be realistic about what they can expect to achieve, especially if your sleeping issues are long-standing problems that may require more specialist interventions. "There was also some concern that continuous noise in the bedroom might actually disrupt sleep." "He found that 'the quality of evidence for continuous noise improving sleep was very low'," says Mikhail. He found that while some evidence existed that white noise machines could help people to fall asleep faster than normal, not all of the evidence stood up to academic scrutiny. In 2020, Mathias Basner, a professor of psychiatry at the University of Pennsylvania School of Medicine in Philadelphia, reviewed 38 studies (opens in new tab) that had looked at using noise as a sleep aid. Another study (opens in new tab) revealed that 80% of respondents slept better than those who weren't exposed to it, and it's also thought that white noise may help mothers in settling babies who are struggling to sleep.īut not all experts agree. A 2017 study in Frontiers in Neurology (opens in new tab) found that adults fell asleep 38% faster when using white noise, while another published in Sleep Medicine (opens in new tab) showed that the introduction of white noise machines in intensive care units helped patients to sleep more soundly. There is a wide range of evidence to suggest that white noise machines might be beneficial in addressing some common sleep problems.

Forty-six decibels should be sufficient, but make sure you don't exceed 85 decibels as that can disturb your sleep and possibly impact your hearing. While sound quality is important, it's key that the device has a timer facility so you know it will turn itself off once you're asleep and so that you can control the volume. Most white noise machines will either create a white noise mechanically or play a digital white noise recording. "This might be useful for shift workers trying to sleep during the day." "Pink noise that mimics sounds such as rain and wind has less higher frequencies than white noise and is said to increase deep sleep," says Kate Mikhail, journalist and author of Teach Yourself to Sleep: An Ex-Insomniac's Guide (opens in new tab). Most will feature a range of sounds to choose from, but will also offer options for 'pink' noise, which has lower frequencies, and 'brown' noise, which is even lower still. White noise machines work through sound or noise masking, a process that creates a blanket of sound that helps to eliminate all those irritating other sounds that might ordinarily keep you awake.
