Research on structure of soundscape in urban open spaces and its design method

Aimed at the visual-centered tendency in landscape plan, a method based on soundscape design was adopted. Through in-situ investigations of soundscape on Saga forest park in Japan, soundscape components of urban open spaces were analyzed using statistical method. When subjective evaluation of favor degree and harmony degree towards these components were elucidated, spatial zoning and its characteristics of soundscape were figured out, and the importance weights of soundscape components were computed. The analysis outcome was applied to the soundscape design of Shengzhou Ting Hu water city in China. The minus and plus design method were put forward, and soundscape components and their spatial formation were designed comprehensively. The results show that soundscape design can definitely identify and express inherent sound components of landscape. Soundscape can become an essential constituent in the landscape plan of urban open spaces, and achieve multi-angle approach for the design and evaluation of landscape.
