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.
