文摘This paper introduced the concept of soundscape, investigated sound environment of old urban residential districts, and explored soundscape elements and soundscape designs. In view of current sound environment features of old urban residential districts and different population groups' preferences for different sound elements, this paper proposed soundscape design methods to improve sound environment of old urban residential districts.
