SEA Modeling And Validation Of A Truck Cab For Sound Package Optimization



Consumers and regulations drive the noise requirements to levels constantly decreasing. For vehicles, noise control strategies include the application of noise control treatments on the vibrating panels. The definition of a sound package often requires balancing conflicting attributes like weight, costs and acoustic performance. A Statistical Energy Analysis (SEA) model can be used to support designers and engineers to optimize the sound packages of vehicles. In this paper, we present the results of a project where we studied the performances of the sound package applied on a truck by developing a full vehicle SEA model in the commercial software VA One.
