This is a software for creating binaural transmission path synthetic sounds that can handle individual transmission paths, transmission path groups, and total noise playback and editing.
Prognoise enables the creation of binaural or monaural synthetic sounds (airborne and structure-borne sounds) for one or more listeners based on the transfer functions and excitation signals (time history data measured in actual operating conditions). Individual transfer functions (e.g., mount transfer, apparent mass, acoustic transfer functions) are integrated and assigned to the corresponding input signals. The corresponding time history signals can be identified, analyzed, and made audible for each node in the model.
