Title: Differentiating between loudness and preference in the case of multi-tone stimuli
Abstract: When exploring sound quality, often a high correlation between pleasantness and loudness can be observed. However, sometimes it is desirable to know to which extent other sound characteristics than loudness are responsible for a preference evaluation. In this respect multi-tone sounds with rich perceptual aspects are interesting test sounds. This talk will present a separate determination of preference and loudness by comparing a test sound of interest with a reference sound. Using an adaptive paired comparison the points of subjective equality (PSEs) for preference and loudness between test and reference sound are separately measured—“Which sound is louder?” and ”Which sound do you prefer?”—by varying the test sound level in an adaptive staircase manner. The level changes affect both loudness and preference evaluation of the test sound. The results of these experiments are level differences ΔL between the test and the reference sound at which equal preference and equal loudness are reached between them. (Similar procedures have been employed to determine equal loudness contours.) It will be shown, with multi-tone sounds as examples, how this method reliably differentiates between loudness and preference.
