Advanced Transfer Path Analysis (ATPA) is a test-based numercial technique allowing the diagnosis necessary to solve vibro-acoustic problems. For vehichel applications, the main purpose consist in raking the contributions fo potential sources or potential transmitting points, distributed around a cabin and creating noise at a receiving passenger location. The classic Transfer Path Analysis (TPA), as commonly know, has one objective: giving the contributions of the sources at the receiver points, independently of their trnasmission path.  Using the ATPA technique, the transmission path are quantified and ranke. This technique complements the possibilities of the classical TPA method, by allowing the determination of the relative contributions of the selected structure and airborne transmission path. Using the information extracted from the application of this theory, the mechanical component to be modified can be identified. From taht point, the decision can be taken to act directly on the source or on the structural elements. This paper starts by giving a short theoretical description of the method. Then, the steps of the experimental procedure applied, the tools used, and the exploitation of the data are described based on a experimental case realized in controlled conditions. Finally, the range of application of the method and of the tools used is described based on a real case.
