基于听觉感知特性的中国民族乐器音色属性分析与建模研究

中国民族乐器是中国传统音乐文化的重要组成部分，但长期以来关于我国民族乐器音色属性的研究较为滞后，这给我国民族乐器工业和民族音乐发展带来诸多不利影响。本项目以乐器的音色属性为研究对象，以客观测量数据为基础，综合运用音频信息处理、音乐声学、实验心理学等多种实验方法和技术手段，围绕如何挖掘计算机能够处理的、能够反应人耳对乐器音色主观感受的音色特征这一科学问题开展系列研究。为此，本项目拟建立用于描述乐器主观听感的音色评价术语体系，构建适用于乐器音色分析的客观声学特征参数集，探寻音色主观听感与客观参数之间的关系，构建乐器音色的感知特征参数模型，并在此基础上研建相关系统工具、开展应用验证。通过本项目的研究，不仅为乐器音色的定量分析提供了理论基础和技术手段，也为在数字化条件下实现中国音乐文化的传承与创新发展提供科学数据，对于推动我国音乐声学领域的发展和民族乐器的产业化进程具有重要意义。

Chinese musical instrument is an important part of Chinese traditional music culture. For a long time, the systematic and comprehensive research on the timbre of Chinese musical instrument is almost blank, which brings a lot of adverse effects to the development of Chinese musical instrument industry and Chinese music. This project takes the timbre properties of Musical Instruments as the entry point and research object, and is based on objective measurement data. In this project, a variety of research methods and experimental means such as audio signal processing, music acoustics and experimental psychology are integrated to study the core scientific problem of how to construct timbre characteristic parameters that can be processed by computers and reflect people's subjective feelings on the timbre of musical instruments. Therefore, this project intends to establish a timbre subjective evaluation term system to describe instruments sound, build the objective acoustic characteristic parameter set of instrument timbre, explore the relationship between the subjective perception characteristics and objective acoustic parameters of the timbre, build the subjective perception characteristics model of the musical instruments timbre, and on this basis, develop system tools and carry out application verification. The research of this project not only provides theoretical basis and technical means for the quantitative analysis of musical instrument timbre, but also provides scientific data for the realization of the inheritance and innovative development of Chinese musical culture under the condition of digitalization. It is of great significance to promote the development of music acoustics and the industrialization of Chinese musical instruments.
