• Sound from liquid phenomena
• Sonification of continuous processes
• Particle-based liquid models

In interaction and interface design, the representation of continuous processes often uses liquid metaphors, such as dripping or streaming. When an auditory display of such processes is required, an approach to sound-synthesis based on the physics of liquids in motion would be the most convincing, especially when real-time interaction is into play. In order to bridge the complexity of fluid-dynamic simulations with the needs of interactive sonification, we propose a multi-rate sound synthesis of liquid phenomena. Low-rate smoothed-particle hydrodynamics is used to model liquids in motion and to trigger sound-emitting events. Such events, such as solid-liquid collision, or bubble formation, are synthesized at audio rate. The proposed method is applied to the two important cases of liquid falling into a vessel, and of solid object falling into a liquid. Some example applications in interaction design are presented.
