摘要
本文介绍了声强测量技术在某125摩托车噪声控制中的应用,利用开发的CEC声强测量分析系统对该摩托车进行噪声源识别,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 application of the sound intensity measurement technique into noise control of an 125 mL motorcycle is presented. With a sound intensity measuring and analyzing system ECE we developed, the identification of main noise sources of the motorcycle was carried out quickly and accurately. According to the analysis, sevseral noise control measures were taken. As a result, the noise level of the driving motorcycle was obviously reduced.
