Différences entre enceintes acoustiques : une évaluation physique et perceptive

Abstract : We look for relationships between perceptual and physical evaluations of differences between the restitution of timbre by loudspeakers. Our experimental protocol consists in recording the sound radiated by loudspeakers in a room, and submitting the recordings to listening tests under headphones, as well as to signal analyses. The resulting objective and perceptual dissimilarities are compared. First, the correlation between dissimilarities is computed. Then, we abandon the criterion of linearity and take into account the multidimensional nature of the perception of reproduced sound: both types of dissimilarities are submitted to multidimensional scaling analysis, and the resulting spaces are visually compared. Our results showed the importance of using auditory models to differentiate the signals in the same way as listeners did. Objective attributes describing two of the main perceptual dimensions used by listeners are proposed.
