RESEARCH ON ACOUSTIC RADIATION CHARACTERISTICS OF CHINESE TRADITIONAL MUSICAL INSTRUMENT ERHU

摘要

In this experiment, the author used hemispherical microphone arrays to measure the acoustic radiation of Chinese traditional bowed string instrument Erhu in an anechoic chamber. By comparing the radiance characteristics of Erhu under different dynamics to analyze the relationship between dynamics and sound radiation characteristics of musical instruments. Meanwhile, by using the spherical harmonic to reconstruct the Erhu radiated sound field and making the acoustic radiation characteristics of Erhu are visualized.
