ELI5: Why do we say "Shhh" when we want someone to be quiet?
gpt
I would assume it's because a shhing noise is what we hear in the womb, and it calms and soothes babies when you loudly shush them. I've heard that mothers across cultures all "shush" their babies when they are little. Maybe it is ingrained from us very young to continue using the phrase on adults.
