My neighbor, not sure where exactly they were from, but they were from the east, had a newborn some months ago. They had a full week of partying, family and friends visiting. They made as much noise as possible, day and night, literally banging pans and pots. All of this was to get the child comfortable with noise. Even leaving the child to cry so it would get used to being alone sometimes. I have never seen such with a "western" family.
