Abstract
Sound in the interior cabin of cars has been of the great importance nowadays.
The automotive industry has long been fiercely competitive with different
vendors attempting to produce vehicles with better performance, handling and
fuel efficiency. The competition of the automotive industries today is directed on
the reduction of noise in the cars cabin. This paper proposes a new method for
noise studies in the cabin, which frequencies of excitation are lower than 200 Hz.
The topics, which are covered in the paper, include the computation of the
structural and acoustic mode shapes, resonant frequencies of the passenger
compartment, coupling between structure and acoustic effects, and forced
vibration analysis. In this research work noises, generated by cabin's panels, will
be identified and then those, which are main sources of noise generators w
