Auralization of a car has several useful applications, such as comparison of the reproduction sound system of different cars and tuning without requiring the car being available all the time. Auralization of a car by means of using different measured binaural impulse responses (BIR) for each of its loudspeakers is investigated. Four methods are compared: human in-ear, two head and torso systems, and a microphone-array. The microphone-array was considered, as it is used for conventional measurement of car's audio system. It was of interest to find out how good auralization, based on this typical measurement, would be. A subjective test compares real sound in a car to auralizations of driver position for different orientations of the driver's head. Different attributes such as realism and sound stage fidelity were tested. Additionally, BIRs for different angles were compared to corresponding BIRs generated from forwarddirection BIRs. The subjective evaluation results highlight the potential of combining different methodologies to achieve reliable perceptual auralization of a car, while reducing time-consuming measurements.
