ATPA (Advanced Transfer Path Analysis) is a method that allows knowing the noise paths and contributions of a vibroacoustic problem. It is clear that a good quantification of the less dominant contributions is essential in order to maintain the validity of the analysis after the implementation of redesigns and possible modifications. A controlled experiment was carried out with a simple prototype, in parallel with the development of a numerical model to evaluate aspects of the experimental application of the method by means of numerical simulation of experiments. The results show a good correlation of the numerical and experimental model for all transmission paths and provide relevant in formation on its application.
