Sound Machines
Street noise, neighbors, and even your own family members can create noise that makes it hard to sleep or focus. Sound machines aim to solve that problem by covering up distracting noises with soothing sounds. A sound machine night light produces a calming, relatively stable sound to help you stay asleep and prevent other sounds from distracting you or keeping you awake. Sound machines are also called white noise machines as many models produce white noise, which is a specific frequency of noise that sounds like radio static. Models usually also include many sound options to choose from, including natural sounds like ocean waves, rustling wind, and thunder; fan sounds; and ambient electronic sound options. Some even feature lullabies or soothing instrumental music. Sound machines also generally include timer and volume settings.
