So thick exterior walls certainly explain the insular feeling of the typical prewar building, but how about that blissful interior silence, the kind where your upstairs neighbor has to be wearing 19th-century diving boots to be heard clomping around above you? That can be attributed to thick floors. According to Cowley, in today’s buildings, “The floor composition…may be solid two-way cast concrete slabs, a highly efficient slab design that maximizes spans and minimizes floor slab thickness.” Other modern floors are comprised of cast concrete on metal deck, which is also on the thin side and tends to transmit sound—much to the annoyance of many downstairs neighbors. 这个属实吗?
建筑类型和材料不都差不多吗？懂工程的知道吧。像这种建筑都有记载： Required under the New Law to include a large courtyard which consumed more space than the 1879 Old Law''stenements tend to be built on multipleland lots or on corner lots to conserve space for dwelling units, the renting of which is the money-making purpose of the structure. In the early 21st century, a typical street will still be lined with five-story, austerely unornamented pre-law (pre-1879) tenements and six-story, bizarrely decorated Old Law (1879-1901) tenements, with the much bulkier, grand-style New Law tenements on the corners, always at least six stories tall.

能看看像打雷的楼长什么样吗？
去实地，进去看看？
去实地怎么看到钢筋混凝土？看不到楼之间的结构啊，就是地板或地毯啊
