Values of the psychoacoustic parameters loudness in sone, sharpness in acum, roughness in asper, and tonality in tu_HMS for the twelve test stimuli (stimuli A–F of the first experiment in blue circles, and stimuli a–f of the second experiment in violet squares) and the reference stimulus (red triangle). Depicted are the values for the left ear. The values are calculated for the initial sound pressure level of 60 dB(A).
