有效声压是指在一定的时间间隔内，某点的瞬时声压的方均根值。在周期性声压的情况下，所取时间应等于周期的整数倍或比周期长得多。在非周期性声压的情况下，所取时间应足够长，以使平均的结果基本上保持不变。
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。
Higher sound pressure level (SPL) favored both collision efficiency and agglomeration kernel, so acoustic agglomeration increased in the higher-intensity acoustic field.
在有多个噪声源的情况下，通过推导声压级分贝值的运算公式，得出了判定主噪声源的有效方法。
Under the circumstances that there are multi noise sources, we can get the effective method of how to judge main the noice source by deriving the formula of acoustic pressure evel decibel.
数值模拟表明，自相似驱动声压能够有效地加剧气泡的塌缩过程。
The numerical simulation indicates that the rapid collapse of the bubble can be enhanced under the drive of the self-similar sound.
