The Restitution of Timbre by Loudspeakers in a Listening Room: Perceptual and Physical Measurements.
This study deals with the relationships between two parallel evaluations of a panel of loudspeakers: perceptual measurements and physical ones. The sound radiated by the loudspeakers has been recorded. The recordings were submitted to both listening tests and signal analysis. Pair-comparison tests were run using headphones, so the spatial dimension of sound reproduction is not investigated. This first attempt revealed two main perceptual dimensions. They were independent of the tested recording techniques and musical excerpts. We determined a suitable method of analysis for the physical measurements, and then we looked for objective attributes correlated with the perceptual dimensions.
