A dynamic evaluation method of soundscape coordination degree suitable for bamboo forest space

Abstract

The invention discloses a method for dynamic evaluation of soundscape coordination degree applicable to bamboo forest space, which comprises the steps of: 1) determining a number of uniformly distributed measuring points in the bamboo forest space area to be applied; Subjective evaluation test of soundscape coordination degree and level I sound level meter measurement, the subjective evaluation score of soundscape coordination degree and equivalent A sound level of the measurement point are obtained; 3) Based on Weber-Fechner's law and Stevens' law respectively Establish an evaluation model for the coordination degree of geophysical sound, biological sound and artificial sound elements; 4) Select the evaluation model with a greater goodness of fit value as the final evaluation model for this element; 5) Calculate the dynamic evaluation model of the soundscape coordination degree. The invention approximately transforms the sound pressure level data in the bamboo forest space into the corresponding soundscape coordination degree evaluation score, and provides a reference basis for the construction and development of the bamboo forest space in forest parks, nature reserves and even scenic spots.

Description

technical field [0001] The invention relates to the technical field of soundscape, in particular to a dynamic evaluation method for soundscape coordination degree suitable for bamboo forest space. Background technique [0002] Soundscape ecology defines soundscape as a kind of sound energy that can make people feel psychologically. superimposed effects. [0003] In terms of soundscape research, Fastl found that there are significant differences in the subjective evaluation of the two by studying semantic sounds and non-semantic sounds with the same physical characteristics; Blesser et al. studied the psychological factors and temporal and spatial changes of soundscapes It is found that space can not only change the sound propagation, but also give people the emotion of the soundscape and the corresponding behavioral awareness; Aylor, through the study of the leaf sound of pine trees, shows that the leaf sound can improve the signal in animal communication, and this characte...

Problems solved by technology

[0005] Most of the existing technical research only considers the subjective evaluation level of the soundscape, or although the subjective and objective evaluation of the soundscape is carried out, the subjective evaluation and the objective evaluation are analyzed and applied separately, without exploring and solving the deep gap between the subjective data and the objective data. relationship and the mutual transformation of the two values, and the types of cases studied are relatively narrow, so it is difficult to provide an effective method for soundscape resource management in depth and comprehensively
