The experiment was _continuous_ white noise, rather than 'while the baby is sleeping' or 'while the baby is falling asleep'.

From the article:

"""Both Chang and Paula Tallal, PhD -- a researcher who was not involved in Chang's study -- say it is probably not a good idea to intentionally expose babies and infants to nonstop white noise, but they say everyday exposures are probably not harmful for most children."""

"100% sure it's safe"

That's not a thing. Life is risk assessment.
