1·System hardware circuit audio digital signal source achieve this functions: sound signals, sound intensity level control, data communications, liquid crystal display, alarm and power.

系统硬件电路包括音频数字信号源实现声音信号产生、数字声强级控制、多机数据通信、液晶显示和电源等模块单元。

2·Dynamic pressure Sensors can measure a wide range of varying high intensity sound pressure and high level dynamic pressure events.

该传感器可测量各种不同的高强度声压和高水准动态压力。

3·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。
