Abstract:
The coincident of the excitation frequency, generated by the vehicle noise and vibration sources, with the acoustic resonance frequencies of the internal vehicle cavity, gives a full excitation of the acoustic modes and consequently a high noise pressure levels. The objective of this paper is to present experimental results and a numerical model by the finite element method for the determination of the resonance frequencies and acoustic modes of irregular shape of the vehicle cavity.
