Neuroscientist Andrew Huberman covered some science behind exposure to white noise during development/using white noise machines with babies in his episode "The Science of Hearing, Balance & Accelerated Learning". Its nuanced, but he says there is some evidence it can be detrimental to a baby's brain/auditory system if used for long periods of time. https://youtu.be/JVRyzYB9JSY?t=3351
