接收到的回波幅度与理论声压值基本一致，表明实验结果可信。
The received echo wave's amplitude is keeping with the theoretical sound pressure value. So the result of experiment is credibly.
通常存储的信息可能包括的' a '加权的Leq, LN的值，声压值，也许1：3倍频为音调分析信息。
The usual stored information may consist of the 'a' Weighted Leq, LN values, SPL values and perhaps 1:3 Octave Band information for tonal analysis.
声学-结构灵敏度用于预测结构辐射声压随结构设计变量的变化，该值对结构降噪设计有重要意义。
Acoustic-Structure sensitivity is used to predict the change of acoustic pressure when structure design variable was changed, which is significance for reducing noise of structure.
