Abstract：Based on the twovdimensional space Rayleigh integral and the two-dimensional planar sound pressure construction technique, a sound field calculation method of a high frequency transducer was proposed. In order to verify the correctness of the method, the acoustic field of a rectangular piston transducer with 4 piezoelectric components and 1.8 MHz was tested and calculated to obtain the sound pressure distribution at different distances. At 50 cm, the maximum error of the calculation is 8.25%. On the premise of guaranteeing the accuracy, the method effectively improves the sound field measurement efficiency of high frequency transducers.
