Abstract
Vehicle interior noise is one of the harmful environmental factors, It affects the overall efficiency of the vehicle through the physiological and psychological influence on occupant. In the noise reduction design, noise source identification is the primary work of noise control. In the vehicle standing idle or low speed, the engine noise is the main noise source of vehicle. The noise of the engine can come into the passenger compartment through the engine compartment bulkhead. In this paper, one military vehicle interior noise is test in the vehicle standing idle, the spectrum characteristics of the noise are analyzed. The results show that the noise transferred to the passenger compartment is steady and continuous sound when the engine idle working. The noise pressure level is increased with the increase of engine speed. The noise frequency is mainly concentrated in the low and intermediate frequency band.
