Abstract
Liquid-solid interaction produces a characteristic sound which is different from the sound of bubbly water flows. This paper explores liquid-solid interaction sound (LSIS) synthesis. The resulting LSIS consists of two components: bubble sound and impact sound, which corresponding to liquid-liquid collision and liquid-solid collision, respectively. To improve the quality of LSIS, we propose a novel sound enrichment method called Feature Transfer Synthesis (FTS), which is designed to compensate for the differences between the real-world recording and the synthesized sound. We also greatly resolve the synchronization problem during blending the two components of LSIS through a key frame algorithm with normal force and grid surface. Moreover, a generalized dipole model for sound radiation is performed to estimate the LSIS pressure at a listener position. We illustrate our approach through a series of experiments and a perceptual user study, demonstrating the utility of our LSIS synthesis pipeline in producing realistic sounds at practical computational times.
