(English Abstract)
This paper investigates the information related to the radiated sounds during treatment using the extracorporea! shock wave lothotriptor(ESWL). First, we observe the vibration of the objects from the radiated sounds and extract the information about the change of the peak frequency from the relation between the vibration and the radiated sounds. Next, we observe the change of the peak frequency according to the position of the focus and demonstrate that it is more difficult to vibrate objects exactly at the focal point than above or below the focus of the ESWL device. Lastly£¬we analyze the relation between the cavitation and the radiated sounds and examine the benefiting condition for the object fragmentation.
