Vibration mode analysis and estimation of sound power of source for acoustic tube driving by single reed

Abstract

Reproduction of wind instrument using additive manufacturing has been studied for the purpose of cultural property by Takahashi et al. It is known that the material of air reed instruments has little effect on sound quality, indicating the possibility of reproducing the Shakuhachi, a Japanese air reed instrument. On the other hand, in the case of the reproduction of classical oboe, a listening test using short musical phrases suggested the possibility of distinguishing the difference of the real instrument from that the reproduced instrument. Since the vibration of the tube caused by reed vibration is greater in reed instruments than in air reed instruments, it is considered that the sound power of the source caused by the vibration effective on the tone. In this study, a 3-D printer was used to create an acoustic tube driven by a single reed, and the sound power of the source generated by the vibration was estimated by analyzing the vibration modes generated in the acoustic tube.
