Transfer path analysis

A characterisation system for characterising vibrational and/or acoustic transfer path related data of a physical system, the physical system comprising at least one input point and at least one response point, the characterisation system comprising

• an input means adapted for receiving in-situ input data for at least one input point and/or response data for at least one response point of the physical system and for receiving at least one system response function between the at least one input point and the at least one response point, and
• a processing means adapted for applying 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 estimated from said input data and/or response data and said physical system response functions.

A method for characterisation of vibrational and/or acoustic transfer path related data of a physical system, the physical system comprising at least one path input point and at least one response point, the method comprising

• receiving in-situ path input data for at least one path input point and/or response data for at least one response point of the physical system
• measuring and/or simulating at least one system response function between the at least one path input point and the at least one response point, and
• identifying at least one parametric load model characterising at least one path input load acting on the physical system as a function of said path input data, whereby the parametric load models are estimated from said path input data and/or response data and said physical system response functions.
