Efficient Sound Synthesis for Natural Scenes

This paper presents a novel framework to generate the sound of outdoor natural scenes, such as waterfall, ocean, etc. Our method firstly simulates liquid with a grid-based method. Then combined with the movement of liquid, we generate seed-particles which represent bubbles, foams or splashes. Next, we assign each seedparticles a radius with a new radius distribution model. By calculating the bubbles' pressure wave we generate the sound. Experiments demonstrated that our novel framework can efficiently synthesize the sounds for natural scenes.
