In these plots, Mathcad modeling two transducers rotated at 60° towards each other. Compared to the 30° configuration, the interference region is only 17mm in depth from the center of the transducer. And the difference between in-phase and out-of-phase cross-sectional graphs of pressure over width is much less pronounced; pressure varies around a normalized 0.45 pressure regardless of phase.
