The paper reviews the application of the finite element method of analysis to the acoustic design of automobile passenger compartments. Low frequency noise in the passenger compartment is of primary interest, particularly that noise which is generated by the structural vibration of the wall panels. The paper describes the finite element method of analyzing passenger compartment acoustics to diagnose, and to reduce, this noise. The computation of the acoustic modes and resonant frequencies of the compartment is considered, as well as the effects of flexible and absorptive wall panels on the cavity acoustics. The paper also describes the coupling of finite element models of the structural and acoustic vehicle systems to predict the interior noise and to identify the noise sources. Finally, the application of this methodology in the vehicle design stage is discussed. (TRRL)
