有关城市声音空间组合关系的探索--理论收获及"城市声音空间组合寻优及诊断"软件的建立

新软件的前身是ChAOS.ChAOS通过在一个“时间轴”上标识各种类型的噪声源、各种有“社会-文化”价值的声音场景,实现对城市声音环境的高质量再现,在本研究中,一方面加深了对各种类型城市声音空间组合关系的理论认识,提出了“声音贡献和声音需求”理论和“时间齿轮”理论,并把这两个理论作为新软件的运行逻辑;另一方面,通过建立“声音事件档案”和“声音空间比对表”,把涉及城市声音空间相互影响的多维数据整合到软件中.该软件已经能够根据项目实际,自动生成最优声音空间组合供建筑师和城市规划师参考,并且能够自动诊断出各种城市声音空间组合的弱点,很好地补充了“ChAOS”在功能上的不足.

Study on the Relationship of the Combination of the City Sound Spaces--Theoretical Achievement and the Software 'Optimize and Diagnose the Combination of the City Sound Spaces Automatically'

The software ChAOS established by the laboratory LISI (France) and the laboratory CRESSON (France) can represent the city sound environment with high quantity. By the help of GIS system, ChAOS can mark all kinds of the noise sources and social soundscapes with their time sequences in maps. So the Users can understand the sound situation of a region immediately by ChAOS. On the other hand, the weakness of ChAOS is obvious. The short of intellection limits the function of ChAOS. To the mostly common users, what they need are some practical references of the sound-planning of their project. In order to realize this target, in this research, firstly, we expand the knowledge about how the sound spaces infect each other when they encounter. Then, we establish two theories, that is, "The contribution and the requirement of the sound space" and "the time gear between two sound spaces". And we use them as the logic structure of the new software. On the other hand, we use "the sound case form" and "the sound space contrast form" to integrate all kinds of useful data of each sound spaces in to the software. Now, in the background of the real project, the software can help us realize the optimization of the combination of the sound spaces and help us diagnose the weakpoints exist in the combination. We believe that the function of this new software can make up the weakness of ChAOS.
