In this publication a validation of common Transfer Path Analysis (TPA) methods on a passenger car is presented to motivate the necessity of further improvements of the current approaches. During the improvement process a specific setup for verification measurements has been designed. This setup eliminates errors corresponding to unconsidered noise sources, bad accessibility for excitation points of the applied forces and temperature influences. Additionally the design allows the measurement of all applied forces and therefore establishes the possibility to compare calculated forces of each source to actually applied forces. Based on these measurement results new TPA approaches could be developed. Those improved TPA strategies and their potential will be presented in this paper. Their application will optimize and increase the efficiency of passenger car interior noise improvement in the vehicle development process. It was shown in this publication that a number of errors can occur when applying a TPA on a passenger car. Additionally, it has been shown that these numerical, as well as measurement based errors can cause differences between simulated and actually measured source contributions to interior noise of more than 10 dB. Therefore, optimized methods have been developed in order to open new ways to a more accurate and time saving TPA analysis procedure. Especially the TPA FORM approach has a high potential to fulfil these requirements.
