Chinese lute timbre quality evaluation method based on vibration acoustics

The invention discloses a Chinese lute tone quality evaluation method based on vibration acoustics, and belongs to the field of acoustics evaluation. The method comprises the following steps: acoustic simulation of Chinese lute vibration; performing expert evaluation and spectral analysis on timbre quality of the Chinese lute; evaluating a subjective and objective combined Chinese lute vibration sound field; the Chinese lute string vibration process is analyzed, and Chinese lute string vibration equations under different working conditions are obtained and can be quantitatively analyzed; key indexes are extracted from the angles of the time domain and the frequency domain, calculation and analysis are carried out, and the sound field quality is evaluated based on the Chinese lute acoustic characteristics; establishing an expert evaluation system, and performing subjective and objective combined pipa spectrum analysis: establishing a relation between subjective hearing and pipa spectrum characteristics by util
