Worldbuilding
Noise rules tell you more about a city than its grand buildings do.
Who is allowed to shout in the street, ring bells after dark, complain in public, or make a nuisance of themselves without consequence? Usually not the people doing the actual work. The regulations are never just about order. They are about whose inconvenience counts as disorder.
A city that fines hawkers for calling out, but excuses gentlemen from drunken singing, has already done the worldbuilding for you. Quiet is rarely neutral.
