The best sound machines for helping you sleep are designed to generate white noise that’s both soothing and helps mask all the other distracting background sounds that keep you awake. Some of the first sound machines literally used a fan to generate sound, and some still do—though many modern alternatives use digital audio to simulate a wide variety of natural sounds including rain, ocean and jungle sounds. Many sound machines are adjustable so you can fine-tune the sound they make; others have clocks, timers and night lights built in. No matter what you’re looking for, check out our roundup of the best sound machines to help you get a good night’s sleep.
