Abstract
An impact sound synthesis method was proposed based on a ball-plate collision model to synthesize impact sounds coming from arbitrary material plates. The impact sound synthesis method for any virtual material was given in a two-dimensional perception space with the help of interpolation functions among aluminum, glass and wood. Two subjective evaluation experiments were designed and carried out. The effect of the use of synthetic sound and original recording for material identification was studied respectively in Experiment 1. The sound continua corresponding to gradually varied material properties were synthesized, and corresponding material control strategies were evaluated by Experiment 2. The results show that listeners can identify material of plates by using the synthetic sounds better than by using the recordings, and the material identification result has the same varying trend as the damping, thus the validity of the impact sound synthesis method is confirmed.
