Comparison of Evaluation Methods for the Quality Assessment of Audio Signals

When evaluating audio signals not only the overall audio quality but also the underlaying quality parameters are of high interest. For this purpose relevant quality features, e.g., attribute and vocabulary lists, have been determined by several researchers. When evaluating the quality description of a set of audio signals with a few predefined quality features an appropriate evaluation design has to be found. This study presents a comparison of two evaluation paradigms. On one hand a single-stimuluswith-multiple-attributes method and on the other hand a multi-stimulus-with-single-attribute method were used for evaluation of the same stimuli and quality attributes.
