声音传感器的作用相当于一个话筒（麦克风）。它用来接收声波，显示声音的振动图象。但不能对噪声的强度进行测量。
还可设置AD转换器、信号调理电 路和环境噪声传感器，以便直接监测。
An AD (analog-digital) converter, a signal conditioning circuit and an environment noise sensor can also be arranged so as to monitor directly.
提出的方法不仅能够有效地消除传感器随机噪声的影响，而且还能够很好地保持遥感图像上重要的细节边缘和影像质量。
Our methods not only effectively remove the impulsive noise caused by sensors, but also preferably preserve important detailed edges and image quality in remotely sensed images.
基于线性无偏最小方差估计理论，提出了一种任意相关噪声异类传感器非线性系统状态矢量融合算法。
Based on linear unbiased minimum variance estimation theory, a fusion algorithm which fused the state vector of nonlinear systems with dissimilar sensors with arbitrary correlated noises is developed.
