摘要
本文介绍了声强测试的基本原理和声强测试技术在CB2 5摩托车噪声控制中的应用 ,利用CF -6 40 0声强测试分析系统对该摩托车进行主要噪声辐射源识别 ,快速、准确地找到其主要噪声源。通过有针对性地采取降噪措施 ,使该车行驶噪声显著降低。
In this paper, the basic theory of sound intensity measurement technique and its application on CB125 motorcycle is presented. With a sound intensity measuring and analyzing system CF-6440, the identification of main noise radiation source for CB125 was carried out quickly and accurately. According to the analysis, noise control measures were taken. As a result, the noise level of driving motorcycle was obviously reduced.
