Beijing megablock with 30k residents and vibrant commercial / social activities on ground floor is a nice taste of new urbanism. That said, dancing grannies with boom boxes blasting until 10pm on a school night is what noise regulations are for. And at least in my old compound, security had a very hard enforcing it. Hopefully this is an addressible problem for headphone companies when wireless broadcast technologies advances.
