Korean bell has mode pair because of the slight asymmetry in the axi-symmetric structure. Beat phenomenon which means the periodic repeat of the strong and the weak sound, occurs due to the interference of the mode pair. After casting the bell, beat control operation is necessary to adjust the clarity and the period of the beat. In the control of the bell, the extraction of the mode data is most important. However, in case of a large bell, striking is performed by a heavy wooden hammer. In this case, it is very difficult to measure the accurate data of the striking force. Thus, it is not available to extract the mode pair by the general modal testing using frequency response function between the input and the output signals. In this paper, ODS method is appplied to a bell in order to obtain the mode data using only the response signal. Using the ODS method mode pair data can be obtaind and beat control is avaiable in the casting site.
