Roughness Prediction for Complex Acoustic Stimuli
Original language description
Vencovský [ISMA2014, p. 483-488] introduced a new roughness model and showed its performance in comparison with listening tests for three types of complex acoustics stimuli: amplitude-modulated harmonic complex tones, real samples of pathological voices(sustained vowel /a/), harmonic intervals of the chromatic scale composed of two harmonic complex tones (dyads). This study extends his results. It adds a new type of stimuli (low-frequency harmonic complex tones), slightly changes the method used to estimate roughness, and, for a comparison, depicts results for the Daniel and Weber roughness model, and the Leman synchronization index (SI) roughness model. The Vencovský model performed well for all of the stimuli. The Daniel and Weber model performed well for the first type of stimuli, but its results were poor for the rest of the stimuli. The SI model performed well for the first three types of the stimuli but poorly for the low-frequency harmonic complex tones.
