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.
本文用聲強法在工作現場對大型汽輪發電機組中的發電機部分進行了聲功率級測量。
Higher sound pressure level(SPL)favored both collision efficiency and agglomeration kernel, so acoustic agglomeration increased in the higher-intensity acoustic field.
聲壓級增大不僅使團聚核函數增大，也增大了碰撞傚率，使高聲壓級時的團聚更有傚。
System hardware circuit audio digital signal source achieve this functions:Sound signals, sound intensity level control, data communications, liquid crystal display, alarm and power.
系統硬件電路包括音頻數字信號源實現聲音信號産生、數字聲強級控制、多機數據通信、液晶顯示和電源等模塊單元。
