为了合成任意材料板的冲击声，提出了一种基于球-板撞击模型的冲击声合成方法，并进行了感知验证。通过在铝、玻璃和木材三种材料之间进行差值的方法，给出了二维材料感知空间中任意虚拟材料的冲击声合成方法。设计并完成了两组主观评价实验，实验1通过材料辨识实验研究了合成声和录音对材料辨识的影响，实验2产生材料渐变的冲击声连续统，并对材料控制策略进行感知评估。结果表明，与录音相比使用合成声可以获得更好的材料辨识结果，此外听者对材料的辨识结果与阻尼的变化趋势一致，从而验证了本文冲击声合成方法的有效性。

Impact sound synthesis method is given 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 is given in the two-dimensional perception space, through interpolation functions among aluminum, glass and wood. Two subjective evaluation experiments are designed and carried out in this study. The effect of the using of synthetic sound and recording for material identification is studied in Experiment 1. The sound continua are synthesized with varied material properties, and corresponding material control strategies are evaluated by Experiment 2. The results show that listeners can identify materials of plates better using synthetic sounds in comparison to recordings, and the material identification results has the same variation trend with damping, thus the validity of the impact sound synthesis method is confirmed.
