Third-octave analyses describing two perceptual dimensions of sound reproduction and the resulting overall perceived dissimilarity between loudspeakers or headphones

Résumé

Many objective measurements have been proposed to evaluate sound reproduction, but it is often difficult to link measured differences with the differences perceived by listeners. In the literature, the best correlations with perception were obtained for measures involving an auditory model. The present study investigated simpler measurements to highlight the signal processing steps required to make the link with perception. It is based on dissimilarity evaluations from two previous studies: 1 study comparing 12 single loudspeakers using 3 musical excerpts, 1 study comparing 21 headphones using 2 musical excerpts, and both studies highlighting 2 perceptual dimensions associated with the relative strengths of bass and midrange. The objective approach compared several signal analyses computing the dissimilarity between the spectra of the recorded sound reproductions. The results show that a third-octave analysis can accurately describe the overall dissimilarity between the loudspeakers or headphones and the two underlying perceptual dimensions.
