M-序列相关技术在隔声测量中的应用

Application of M-sequence Correlation Technique in the Measurement of Transmission Loss

本文介绍了应用M-序列相关技术来进行隔声测量的若干实验工作。研究表明,即使在强背景噪声环境中仍能使用这种方法来进行隔声测量,并能获得十分满意的测量精度。

The measurement technique, which measures a transmission loss by using a periodic. pseudorandom sequence, was studied through experiments. The method can be used in a quite noisy environment and can obtain a satisfactory measuremental accuracy.
