摘要

为探究竹林空间中声景的物理量和人主观协调感受的心理量之间的关系。本研究从声景生态学与心理物理学的角度，通过语义差异法对竹林空间中不同声景元素的协调度进行主观评价，同时测量评价位置的客观物理指标，最后通过对主客观数据进行拟合建立了竹林声景协调度评价模型（Coordinating Evaluation of BambooGarden Soundscape, CEBGS）。研究结果表明：①地球物理声在较安静时能使评价者产生较协调或一般的协调感受，但声压级增大后会产生一定的失调感；②生物声能使评价者产生较稳定的协调感受，并且在声压级增大后也不会产生显著的失调感受；③人工声能使评价者产生较失调的心理感受；④各声元素的主客观数据拟合趋势符合心理物理学法则，其中地球物理声和生物声相对倾向于费希纳法则，而人工声倾向于斯蒂文斯法则。最后，得到了适用于竹林空间的声景协调度评价模型，为科学合理的竹林空间环境建设和提升提供了有效方法和参考依据。

Abstract

Here, the relation between physical quantities to represent a bamboo garden space’s soundscape and psychological quantities to represent human subjective feelings was explored. The semantic difference method was used for observers to evaluate the coordination degree of different sounds and sights in a bamboo space, the objective physical indexes of observers’ positions were measured, and eventually the evaluation model for bamboo gardens’ soundscape coordination degree was established from the perspective of the soundscape ecology and the psychophysics. The results showed that when geophysical sounds are lighter, they make evaluators produce more coordinated perceptions or general coordinated ones, while their sound pressure levels rise, evaluators produce a certain uncoordinated feeling; biological sounds make evaluators produce a steady and coordinated sensation, while their sound pressure levels rise, evaluators don’t have a significant uncoordinated feeling; artificial sounds make evaluators produce a more uncoordinated feeling; the fitting trend for subjective data and objective ones of various acoustic elements conform to principles of the psychophysics, geophysical sounds and biological ones conform to Fechner's law, artificial sounds conform to Stevens' law; the proposed evaluation model is suitable to bamboo gardens’ soundscape coordination degree, it provides a reference for scientific and reasonable construction of bamboo gardens.
