试验环境下耐高温噪声测量技术概述

Summary of Acoustic Measurement Technology of High Temperature Resistance in the Test Environment

本文针对试验环境下的耐高温噪声测量,介绍了加装冷却水套、光纤传声器、等离子体传声器以及声波导管等四种噪声测量技术,简述了每种技术的基本原理,并用实例介绍了每种技术的应用情况。其适用的环境条件不同,性能也有差别,工程应用时应根据具体试验工况进行相应的选择。

According to the acoustic measurement technique of high temperature resistance in the test environment, this paper introduces four kinds of techniques, including jacket cooling, optical fiber microphone, plasma microphone and acoustic pipe. This paper briefly introduces the basic principle of each technique, and the application of each kind of technology for example. The suitable environment conditions are different, the performance also has the differences, engineering application should be based on the specific conditions of the corresponding selection.
