Particle velocity of the system of a pair of square transducers and that of circular ones are computed precisely and are compared with each other. The principle for the computation is based on Rayleigh's theory, and numerical multiple integration is achieved. In the computation, repeated trapezoidal rule is used, and how the result converges with the increase of the number of subintervals is investigated. The convergency of the system of a pair of square transducers by numerical quadruple integration and that of circular transducers by numerical double integration with analytical decrease of integral multiplicity are revealed to be different. Particle velocity and velocity potential multiplied by 2 π/λ show almost the same convergency.
