Abstract

An original software-based system, featuring two different tools,
is here proposed for vehicle audio quality assessment. The first
one performs the acquisition of relevant data for system modelling
and for cancelling the undesired effects of the acquisition chain.
The second offers a user-friendly interface for real time
simulation of different car audio systems and for both objective
and subjective evaluation, where the listening procedure is
directly experienced at PC workplace. The validity of this
approach has been examined through a subjective listening test set
(more than 50 participants and three cars involved), developed by
means of a dedicated software environment and based on appropriate
ITU recommendations. Experimental results have shown that the
quality rating delivered by conventional in-car procedure is
confirmed when the software-based approach is used.
