Abstract
Binaural Transfer Path Analysis and Synthesis techniques have been developed for the prediction of vehicle interior sound in the time domain. These methods not only allow the prediction of order levels, spectra and vibrations but also the binaural auralization. Recent method extensions permit the combination of measured and simulated excitation data for the time domain approach of BTPS using a newly developed order generator considering phase synchronization of all input data. This paper describes advanced engineering tools and improved methods developed for vehicle sound design and comfort judgments by means of a BTPS model of a Nissan vehicle.
