Component-based transfer path analysis (TPA) has been developed to predict the exterior sound level contribution from noise-generating components upfront in the design cycle without having to physically integrate them into the vehicle. Virtual pass-by noise predictions for different vehicle variants can be reached by combining the characterization of each component source with simulated vehicle noise transfer functions (NTF). The objective of this work is to implement the technology in a time-domain framework to enable listening tests. The time-varying filters obtained from measured noise transfer functions are implemented as infinite impulse response (IIR) filters. The technique is validated on an automotive example.
