民族管弦乐队音响特征的定量化研究——“尖、扁、杂、吵”的声学诠释

Quantitative Study of the Acoustic Characteristics of Chinese Ethnic Orchestral Music:Acoustic Interpretation of"Sharp,Flat,Chaotic and Noisy"

从系统构成的角度来看,管弦乐队实际上由信号发生、信号控制、操作系统与应用软件四个部分构成。文章对中西管弦乐队系统的各构成部分进行对应比较,分析导致二者音响特征形成差异的客观参数,并运用声学测量与分析方法,揭示民族管弦乐队主观听觉产生“尖、扁、杂、吵”感知的物理成因,由此形成民族管弦乐队音响特征定量化研究的结论。

From a system construction standpoint,the orchestral music system is comprised of four fundamental components:signal generation,signal control,operating system,and application software.This paper conducts a comparative analysis of the corresponding elements within Chinese and Western orchestral music systems,aiming to discern the objective parameters that contribute to the divergence in their acoustic characteristics.Employing acoustic measurement and analysis techniques,the study unveils the physical factors underlying the subjective perception of"sharp,flat,chaotic,and noisy"attributes in ethnic orchestral music.Consequently,the paper draws definitive conclusions regarding the quantitative examination of the acoustic traits specific to ethnic orchestral music.
