| Abstract: | 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. |
