摘要： 汽车的进气噪声能够直接影响车内的噪声水平和声品质。在车内动力感声品质研究过程中,需要借助进气噪声能量增强车内噪声的动力感,在发动机半消声室单纯测试进气噪声的传统方法无法满足汽车声品质研究需要。因此,本文中提出了一种在整车半消声室NVH底盘测功机上同时获得进气噪声和车内噪声的方法,通过现场测试人员的主观感受和测试数据的分析,验证了该方法的有效性,能够获得相对纯净的进气噪声;并对研究车型急加速工况下的进气噪声和车内噪声品质的关联性进行了分析,通过对4个典型的声品质客观参量的对比分析发现进气噪声是车内动力感声品质实现中比较优秀的噪声源,其研究对汽车声品质设计具有重要意义。

Abstract: The intake noise of a vehicle can directly affect the noise level and sound quality of the vehicle. In the process of the research of interior dynamic sound quality, it is necessary to enhance the dynamic sense of interior sound by the energy of intake noise. The traditional method of simply testing intake noise in the engine semi-anechoic chamber cannot meet the need of automobile sound quality research. Therefore, this paper proposes a method to obtain air intake noise and interior noise simultaneously on the NVH chassis dynamometer of the vehicle half-anechoic chamber. Through the subjective feeling of the field tester and the analysis of the test data, the effectiveness of the method is verified, and relatively pure intake noise can be obtained. The correlation between intake noise and vehicle interior sound quality under the condition of rapid acceleration is analyzed. Through the comparison of four typical objective parameters of sound quality, it is found that the intake noise is an excellent noise source in the realization of dynamic sound quality, which is of great significance to automobile sound quality design.

Key words: intake noise, vehicle interior noise, noise separation, sound quality
