Method for coordinating evaluation of dynamic soundscape in bamboo

Abstract

The invention discloses a method for coordinating evaluation of dynamic soundscape in bamboo. The method comprises steps of 1) determining a number of measurement points evenly distributed in a bambooarea to be applied; 2) obtaining the coordinating evaluation scores and equivalent A sound levels of the measurement points by simultaneously performing multi-person soundscape coordinating evaluation testing and Class I sound level meter measurement; 3) establishing an evaluation model based on the coordinating degree of coordination between Geophonies, Biophonies, and Anthrophonies elements based on Weber-Fechner's law and Stevens' law; 4 ) selecting the evaluation model with a greater degree of goodness of fit as the final evaluation model of the element; and 5) calculating a model for coordinating evaluation of the dynamic soundscape. The method approximately converts the sound pressure level data in bamboo into corresponding coordinating evaluation scores of the soundscape, and provides a reference basis for the bamboo construction and development in forest parks, natural 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...

AI Technical Summary

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
