SPL sound pressure level 声压级 ; 声压水平
Higher sound pressure 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。
Sound pressure level (SPL) sound pressure level is a measurement of the pressure fluctuations of a sound wave as it propagates through the air.
