sound intensity level

基本解释

In this paper, the sound power level of large turbogenerator in operating site is determined by means of sound intensity measurement.
本文用声强法在工作现场对大型汽轮发电机组中的发电机部分进行了声功率级测量。
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。
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。
