| Abstract: | This paper studies distribution in sound field of the concave spherical transducers under different conditions. Theoretically, it first calculates the sound pressures distribution. Distribution of different apertures near the focus of sound pressure is simulated by using Matlab and Mathamatic software.The sound pressure level and the focal range are provided in different situations.This has certain reference significance for the application of transducer in medical science. |
