摘要
在汽车车身的隔声性能试验中,对声压和声强的两种测量法,进行了比较分析。结果表明,这两种测量方法各有其特点,对汽车车身隔声量的改进及降噪圴有较好的指导作用。
In this paper, two measurement methods, sound pressure method and sound intensity method, for the measurement of sound insulation performance of vehicle＇s body are compared and discussed. It shows that the two methods have their own characteristics, and both of them play instructive role in improvement of sound insulation effect and noise reduction.
