The sound quality of a car audio system is an integral part of the perceived quality of a car for many customers. Accordingly, car manufacturers are always looking for ways to improve and optimize their audio systems. This contribution compares two approaches for quantifying the perceived audio quality. Several real car audio systems are evaluated both by a speci?c listening test and a novel instrumental assessment method that is based on a recently introduced set of analyses for audio quality. The comparison of the results of both approaches validates the instrumental method for this application scenario and shows that the method provides the same information as the listening test in a fraction of the time.
