Verbal Elicitation and Scale Construction for Evaluating Perceptual Differences between Four Multichannel Microphone Techniques
A verbal elicitation task using triadic comparisons was completed by eight listeners to explore the adjectives that describe the audible differences between solo piano performances captured using four different multichannel microphone techniques. Although the elicited terms differed somewhat between listeners, a set of five bipolar adjective pairs were found to represent the most salient differences between the auditory imagery associated with multichannel-loudspeaker reproduction of the piano performances. These adjectives were used as the anchors for five attribute rating scales on which the same eight listeners rated each of the 32 stimuli that had been presented for triadic comparison. Stepwise multiple regression showed that ratings on three of the five attributes successfully predicted those listeners' preference ratings for the same stimuli.
