In this study four rating scales for perceptual evaluation of Preference were compared: 9-point hedonic, Continuous Quality Scale (CQS) (e.g., used in ITU-R BS.1534-3 [1], “MUSHRA”), Labelled Hedonic Scale (LHS) [2], and a modified version of the LHS. The CQS was tested in three configurations to study the role and impact of the reference and anchor stimuli, namely: A full MUSHRA test with anchors and references, a test without references, and a test with neither references nor anchors. The six test configurations were tested with two groups of AAC codec qualities: High and Intermediate quality ranges. Results showed that the largest difference in scale usage were caused by having a declared reference, but also that the scale range usage is not strongly related to stimuli discrimination power.
