Acoustic Measurement and Modeling of the Traditional Chinese Instrument Guzheng in Digital Transformation: A Case Study of Spectral and Resonance Analysis of Standard Pitch A440

This paper aims to explore the acoustic measurement and modeling of the traditional Chinese instrument, the guzheng, in the context of digital transformation, focusing on the spectral and resonance analysis of the standard pitch A440. By employing various tools to conduct detailed analyses of the frequency response and resonance characteristics of guzheng audio, the study clarifies the performance of its timbre across different frequency bands and the distribution of resonance peaks. This research reveals the complexities of guzheng’s timbre, and the challenges posed by digital transformation, proposing solutions for optimizing spectral models and resonance data processing. The findings provide theoretical support and technical guidance for digital recording, music creation, preservation, and transmission of the guzheng.
