摘　　要：传统的基于客观指标的噪声评价方法已经不能满足新车型的开发要求。为了更好地体现客户的主观感受,在评价噪声的过程中引入基于主观评价的声品质方法。文章详细介绍了语言清晰度、响度及尖锐度3个声品质参数的计算方法,对4辆不同品牌排量为1.3 L的两厢乘用车进行车内匀速噪声测试,并进行了客观评价和主观评价。通过对比可以看出,基于主观的噪声评价方法更真实地反映了车辆的噪声水平和品质。The traditional objective methods of noise estimation can not meet the requirements of the new cars development. In order to reflect the subjective perception of customers, the sound quality method based on subjective estimation is introduced in the process of noise estimation. The calculation methods of sound quality parameters-- speech articulation, loudness and sharpness is described. Interior constant speed noise test is conducted with four different brand 1.3 L hatchback passenger cars. Objective and subjective estimation is proceeded. By comparison we can conclude that the noise level and sound quality are reflected by subjective noise estimation.
