Abstract：Based on the theory of two-dimensional plane acoustic pressure construction technology, combined with the spatial Fourier transform near-field acoustic holography technology, a sound field measurement method with high measurement efficiency was proposed. A rectangular piston transducer array composed of four piezoelectric elements was used as a measurement object, and the sound field simulation and experimental measurements were performed to verify the measurement accuracy and efficiency of the measurement method. The results showed that the method improves the measurement efficiency by 560 times compared with the surface scanning method. Compared with the integration method, the calculation speed increases by two times. This method can be effectively applied to the sound field measurement of high-frequency transducer arrays.
