White noise means that the power of the frequency component of a sound is uniform throughout the audible range. The white noise heard by the human ear is usually a rustling noisy sound.

Especially when the newborn baby has just left the mother's womb and arrived in an unfamiliar environment, it takes a while to adjust.

Strange sounds in the living environment will make the baby feel uneasy and irritable, and white noise and noise in the womb have a relatively fixed frequency, which can help dilute the stimulation of external strange sounds on the baby, divert the baby's attention, and let the baby calm down.
