We get and analysis the data of the reverberation, noise and acoustic pressure level of the Conference Hall and Lecture Hall in some northern university in measurement.

实测和分析了北方某大学的甲报告厅和乙会议厅的混响时间、景噪声、场级等数据。

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。
