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.
传统的模极大值序列处理方法虽然可以保留信号特征，但降噪后的信号在奇异点有毛刺和轻微的振荡。
Although traditional processing method of modulus maximum array can retain characteristics of signal, the signal after de-noising exists thorns and slight oscillation at singularity point.
信号降噪是指滤除信号的高频噪声从而使信号尽量接近真实值，这是信号处理的关键环节。
The signal denoising is a method for filtering the high-frequency noise of the signal and makes the signal more precise.
