How white noise helps babies sleep

White noise creates a consistent sound environment that masks sudden noises which can wake a sleeping baby. Inside the womb, babies hear a constant swooshing sound of about 80 decibels, so white noise mimics this familiar environment.

Studies show that white noise can help babies fall asleep faster and sleep longer. The AAP recommends keeping sound machines below 50 decibels and placing them at least 7 feet from the crib.
