摘要
声强测试分析方法是一种有效的噪声源识别和声场分析方法。采用声强测试技术对某轮式装载机进行噪声测量,得出其声场分布规律,快速准确地找到主要的噪声源,在此基础上提出具有针对性的降噪措施,获得令人满意的效果。
The sound intensity method is an effective method in noise source identification and acoustic field analysis. In this paper, the sound intensity technique was applied to measure the noise of a wheel-loader. The sound field was obtained. The exact locations of noise sources were identified very quickly. Based on the analysis, some methods for noise reduction were suggested. And satisfactory results were obtained.
