摘要
车内噪声由多种噪声源混合组成,准确分析对车内噪声影响最大的噪声源是控制车内噪声的关键。运用声谱分析技术,准确、快速查找出对车内噪声影响最大的传动部件,并作出相应改进,以达到降低噪声的目的。
The interior noise is composed of multiple noise sources, and the accurate analysis on interior noise can be found that the biggest impact of the noise source is the key to control interior noise sound spectrum analysis technology. It is used to find the biggest influence on interior noise of driving part quickly and accurately, and make corresponding improvements to reduce noise.
