摘要

To date, ‘Urban Design’ has seldom accounted for the quality of the acoustic environment.The significance of sound in the urban environment is understated. This isevident in design attitudes towards Urban Acoustics, which are essentially objective;based on ‘Noise Control Methodologies’, limited by quantitative values and void ofsonic variety. The aim of this thesis is firstly, to determine whether an acoustic agendacould be successfully introduced into the urban design process, and secondly, to assessthe aesthetic impact of imposing such an agenda on the built environment.To explore these ideas, the thesis combined research from three fields; Urban Design(‘Public Places, Urban Spaces’ by Carmona et al.), Urban Acoustics (‘Urban SoundEnvironment’ by Jian Kang), and Soundscape Philosophy (founded by R. MurraySchafer). A series of experiments were then conducted using noise propagation software‘CadnaA’, which studied the acoustic performances of different Street and OpenSpace Layouts. Conclusions drawn from these experiments and the analysed literatureprovided the framework for an Urban Design Proposal located in central Wellington,which was used as a means to assess the viability of this design approach.The results of the design-research process suggest that an acoustic agenda can beintegrated into the urban design process with relative ease and little conflict, and thatmany of the Soundscape philosophies inherent in Urban Acoustic Design actually complementwell-established Urban Design Principles. Additionally, while this approach ismost effective in acoustically challenging areas, the intrinsic design principles can beadopted to enhance both the acoustic and visual aesthetic of any urban design.

MurraySchafer创立)。然后使用噪音传播软件“ CadnaA”进行了一系列实验,研究了不同街道和OpenSpace布局的声学性能。从这些实验和分析的文献得出的结论为位于惠灵顿市中心的城市设计提案提供了框架,该框架被用作评估该设计方法可行性的一种方法。设计研究过程的结果表明,声学议程可以可以相对轻松和几乎没有冲突地整合到城市设计过程中,而城市声学设计中固有的许多Soundscape哲学实际上是对完善的城市设计原则的补充。另外,虽然这种方法在声学上具有挑战性的领域最有效,但可以采用固有的设计原理来增强任何城市设计的声学和视觉美感。
