Increasing size or frequency of the sound source will lead to that the main lobe of beam become narrow, deputy flap become more, acoustic pressure in the axis become larger and the radiation of sound field become smaller. The influence of product of wave number and sound source size on directivity was discussed, and it was found that the sound field become intense, energy become focused and its directivity become better with the increase of product value. A further analysis on the directivity character of radiation sound field of combination plane arrays of line and rectangular array was carried out on the basis of investigating directivity of round and rectangular piston transducers. Distribution and directivity character of M×N 2×2, 3×3, 3×8 array of line combinations plane arrays and M×N 2×2, 2×6 rectangular combination plane arrays were analyzed respectively. It was found that the more array number, the more complex for the distribution. In the direction of the more array number will make sidelobe suppression, the main lobe relatively prominent and energy more concentrated. The influence of liquid/solid interface on sound field distribution has been discussed, taking the water/steel interface for example, and it was found that the acoustic pressure in the solid will increase when the wave propagates from the small acoustic impendence medium to the large one.
对直径为10mm、20mm、50mm和发射频率为1MHz、2MHz、5MHz的圆形活塞换能器声场声压分布进行比较，发现频率不变声源尺寸增大或声源尺寸不变频率增大，声束的主瓣都会变窄，辐射范围缩小，副瓣增多，轴线上声压增高；对波数与声源尺寸的乘积对指向性的影响进行讨论，发现随着乘积数值的增大其声场变得尖锐，能量集中，指向性变好；在对圆形活塞换能器和矩形活塞换能器声场声压分布及指向性进行分析的基础上，进一步分析线列阵组合平面阵和矩形阵组合平面阵辐射声场的指向性特征，分别对M×N为2×2、3×3、3×8的线列阵组合平面阵和M×N为2×2、2×6的矩形阵组合平面阵的指向性分布特征进行分析，得到阵元个数及排列对指向性分布的影响规律为：阵元个数越多，指向性分布越复杂，M和N不等的阵列上阵元数较多的方向旁瓣会得到相应的抑制，主瓣比较突出；以水/钢界面为例对液/固界面对声压分布的影响进行讨论，得到声波从声阻抗较小的液体入射到声阻抗较大的固体中声压会突然变大，增大的幅度取决于透射系数。
