It's not just authorities, it's cultural. Some cultures are simply much louder than others. I live in Tokyo and it's generally very quiet here, despite (usually older) apartments having a bad reputation for paper-thin walls. Public transit is generally whisper-quiet (as far as the riders; the trains themselves of course are not), as people generally don't talk much, and talking on the phone is prohibited. People who make too much noise will probably get the police called on them, but that only works in a society where there's a culturally low tolerance for noise, so it's not really up to the authorities.
