영문 초록

To investigate the characteristics of the sound-pipe on the top of King Song Dok bell, using computer simulation, the throat impedance was evaluated for the straight pipe and conical pipes with vaη1ing taper angles. When sound propagates in a rigid walled, unflanged circular pipe with wavelength larger than radius, the acoustic motion is planar, much as in a bar. The incident sound waves are reflected at the end of pipe and some of them are transmitted. The reflection coefficient and radiation impedance of the sound-pipe of King Song Dok bell were calculated, and the results demonstrated that the high frequency sound is radiated through the sound-pipe. It behaves like a frequency filter.
