The identification of relevant auditory attributes is pivotal in sound quality evaluation. Two fundamentallydifferent psychometric methods were employed to uncover perceptually relevant auditory features of multichannelreproduced sound. In the first method, called Repertory Grid Technique (RGT), subjects wereasked to directly assign verbal labels to the features when encountering them, and to subsequently ratethe sounds on the scales thus obtained. The second method requires the subjects to consistently use theperceptually relevant features in triadic comparisons, without having to assign them a verbal label. Undersuffcient consistency, a lattice representation – as frequently used in Formal Concept Analysis (FCA) – canbe derived to depict the structure of auditory features.
