Higher soundpressure level (SPL) favored both collision efficiency and agglomeration kernel, so acoustic agglomeration increased in the higher-intensity acoustic field.
声压级增大不仅使团聚核函数增大,也增大了碰撞效率,使高声压级时的团聚更有效。

Using the finite difference time-domain (FDTD) method and near field to far field transformation, pressure of the reflected sound from the scattering target is calculated.
This paper describes the principle, construction and experimental results of the standard apparatus for underwater soundpressure by using the free-field reciprocity method.
