Experimental Analysis on Acoustic Characteristics of the Sound-Pipe of King Song-Dok Bell

The acoustic characteristics of the sound-pipe of King Song-Dok bell, which is located on the top, are investigated by experiment and simulation. The experimental results;reflection coefficient, and radiation impedance, demonstrate that the sound-pipe is capable of radiating high frequency(above 300Hz) sound; it behave as damper. It is also found that a waveguide model well presens the acoustic characteristics of the sound-pipe.
