The EU law impose to car manufacturers that their vehicles don't exceed a given noise level. More- over, concerning economical aspects, their customers attach more and more importance to the acoustic quality when purchasing a car. One of the most important source of noise is the pow- ertrain. Despite limited tools existing in the early design cycle, the designers do not have any numerical methods available to choose between several geometries the most favorable according to vibroacoustics. Numerical calculations and experimental tests at the end of the project allow to notice the engine emitted noise. Only expensive and maladaptive palliative solutions can then be applied. This thesis consequently aims at providing methodologies to evaluate...
