Abstract: At present, there are few researches on the visualization using the virtual scanning data of sound field and using the visualized data to make the measurements. A visualization software of ultrasonic field based on MATLAB through APP Designer was developed in this paper. Two kinds of simulation experiments were designed:the simulation of sound field distribution on the sound axis and the simulation of sound pressure on the cross section of the sound axis. It is verified that the sound field changes with different frequencies and radius of the transducer in the same medium, and it also changes in different media while using fixed frequency and radius transducer in different media. The experimental results show that the software developed in this paper was reliable in the simulation of ultrasonic field.
