A method (200) is described for the characterisation of vibrational and/or acoustic transfer path related data of a physical system (100). The physical system (100) thereby may be any physical system wherein vibration or acoustics may play a role. The method (200) comprises receiving (210) input data for at least one input point of the physical system and/or response data for at least one response point of the physical system (100). The method (200) further comprises receiving (220) at least one system response function between the at least one input point and the at least one response point indicative of the transfer of vibration and/or acoustic signals. The method (200) also comprises applying (230) at least one parametric model characterising at least one load on the physical system as a function of said input data, whereby the parametric models are identified from said input data and/or response data and said physical system response functions. The method (200) may have as output a parametric model for the loads present on the system, the determined loads present on the system or the transfer path contributions, e.g. per order or per frequency, and for at least one of the response points. |
