The experimental results in the lab and in a plant show that the monitoring system with the new sensor has better noise rejection performance than other methods.
This paper introduces modal acoustic emission evaluation technique, including its fundamental principles, signal characteristic, noise rejection and source location etc.
本文介绍了模态声发射检测技术的基本原理、信号特征、噪声剔除和源定位等内容。
A system with good normal-mode noise rejection can usually remove this noise from the measurement.
