Triadic comparison tests can derive individual perceptual structures of sound
Evidence
Perceptual structure analysis is an example of an indirect elicitation technique recently used in the field of audio by Wickelmaier and Ellermeier (2007). This approach is based on Heller’s theory of semantic structures (Heller, 2000), where the processes of identification and labelling of perceived characteristics are separated. In the test, the subjects are presented with three stimuli and are asked to indicate if the first two stimuli share a common feature with the third stimulus or not. After verifying that the subjects really use consistently the features that the data indicate, a representation of the individual perceptual structure can be derived indirectly. The method has been applied by Choisel and Wickelmaier (2007) to develop a set of auditory attributes that describe the differences in perception of multi-channel sound reproduction. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 946
