A measurable index ("IQSB") quantifying perceived quality of car stereos has been developed, to forecast aural appreciation. Results of panel interviews and listening tests (in a special "auralisation room") have been correlated with the analysis of corresponding binaural recordings. Two outputs were obtained. First, a model of the subjectively most relevant features was identified, in terms of statistically significant "verbal descriptors". Second, a single-figure index was constructed, function of objective measurable quantities related with audio performance, and well correlating with the average verbal evaluation (both of "naïve" and "expert" listeners). This tool is of great importance for the automotive industry, because it allows for the direct quantification of the audio system performance, significant part of the perceived quality of the product.
