Vibro-Acoustic simulation for vehicle audio design

Acoustic user interfaces and audio experiences are among the leading comfort factors in new vehicle interior designs. OEMs are more and more focusing on loudspeaker design and positioning, to provide the most immersive experience to the customers. The industrial target is to be able to predict the performance of an audio system in early design phases. This paper presents a methodology to model source-receiver transfer functions in a full-scale vehicle cabin and investigates the installation effect of the speakers in a real car door. A hybrid methodology is developed to be able to model the loudspeaker in different environment.
