The sound field excited by high fidelity (hi-fi) audio systems depends on the loudspeaker drivers, their positioning, their enclosures and the listening room. In the case of in-car sound systems, the listening room is the car cabin and its influence is much more pronounced than in typical living-room scenarios. Thus, the user experience results from a complex auditory scene. In certain situations, it is desirable to simulate the resulting auditory scene by means different than the actual audio system, e. g. by using binaural synthesis. In this study, a state-of-the-art binaural synthesis system for living-room scenarios was evaluated with respect to simulate a premium automotive audio system. To this end, listening tests were designed that can identify potential perceptual differences between the original audio system and its simulation. The evaluated aspects include temporal, spectral and spatial attributes. The results show that a convincing simulation of in-car sound systems through binaural headphone reproduction appears to be possible with regard to the evaluated aspects.
