振動板に対向する音響管の放射音特性に関する研究

抄録

This research is directed to xylophone. Xylophone is musical instrument that has side-by-side wooden sound board in general, it is intended for those with resonance tubes under sound boards in this research. I taken out one set of the resonance tube and sound board, treated as system, which led the resonance tube and sound board. Theory of the system that led the two has not been established yet. This research is finally aimed establishment of theory. I was produced in resonance tube and sound board based on the 'la' of the sound of basic. Sound boards of xylophone are carved arched lower, but I was using the aluminum, using rectangular solid in this research. Resonance tube was using vinyl chloride. The result of hanging the sound board, measuring some points sound pressure with or without the resonance tube, I found that there are differences in sound pressure distribution. Therefore, I can be seen that the resonance tube has brought something to the effect space or sound board.
