Calculation of the Effective Mount Transfer Matrix (EMTF), quantification of Indirect Structural Sound Transmission (IFC), and validation of model calculations based on measured structural sound transmission.
TPA – Structural Propagation Sound Analysis is an extension option of the TPA project that enables the quantification of indirectly acting structural propagation sound components using the Effective Mount Transfer Function (EMTF matrix) and Indirect Force Contribution (IFC). Furthermore, TPA – Structural Propagation Sound Analysis supports the execution of validation measurements for structural propagation sound to evaluate the quality of the TPA model and to optimize the mapping accuracy of the synthesis.
