Perceptual Evaluation of a Real-time Synthesis Technique for Rolling Sounds

In this study 6 different versions of a new real-time synthesizer for contact sounds have been evaluated in order to identify the most effective algorithm to create a realistic sound for rolling objects. 18 participants took part in a perceptual evaluation experiment. Results are presented in terms of both statistical analysis of the most effective synthesis algorithm and qualitative user comments. Finally recommendations for future implementations of synthesis techniques and subsequent perceptual evaluations are presented and discussed.
