Convention Paper

Correlation Between Subjective and Objective Data for Quality Loudspeakers

Authors: Staffeldt, Henrik

AES Convention 47 · Paper A-6 · March 1974

Abstract

The aim of the research reported here was to disclose, if possible, connections between a subjective evaluation of quality loudspeakers and their objectively measured data. The research covered listening tests and objective measurements of a series of quality loudspeakers. In the listening tests, the method paired comparisons was used and the loudspeakers were evaluated with regard to 35 subjective qualities. The results of a statistical analysis showed the loudspeakers subjective data in the form of rank order of preference, one for each of the 35 qualities. The uncertainty of the subjective data was also determined. Furthermore it was tested whether the evaluations were dependent on the test subjects, the music examples used in the listening tests, or the sound level of the reproduction. A tentative dimensional analysis showed that the subjective data could be summed up in two psychologocial dimensions. By putting these subjective data up against the objective data, a correlation was observed between, on the one hand, the loudspeaker's power response as well as phase response and on the other hand, the subjective evaluations with respect to the two psychological dimensions.
