摘要
以城市公园声环境为研究对象,研究影响声景观感知属性的本质因素。通过现场调查研究了影响声景观评价的各种因素;选取及模拟典型声景观片段,在实验室内采用成对比较法进行主观评价实验,得到关于各声景观素材的不相似度矩阵;再应用多维尺度分析,获得声景观评价影响因素的维度数。为进一步探讨声景观形成机理、实现声景观客观评价及建模提供了理论依据。
In this paper, auditory perceptual attributes of soundscape involved in urban park acoustic environment are studied. Firstly, various influencing factors related to the urban park soundscape are examined by field investigation. Secondly, by selecting and simulating of typical pieces of the soundscape and using paired comparison, subjective evaluation is made in the laboratory to obtain the non-similarity matrix of the soundscape data. Finally, using multidimensional scaling, dimensionality of influencing fac- tors of the soundscape is obtained. This study provides a theoretical base for further study of mechanism, objective evaluation and modeling of the soundscape.
