摘要
Abstract
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 die two methods have their own characteristics, and both of them play instructive role in improvement of sound insulation effect and noise reduction.关键词
