Sound Generation from Liquid
William Moss and Hengchin Yeh
We present a novel algorithm for simulating the sound generated by liquids.We use a smoothed particle hydrodynamics formulation, modified to allow for the simulation of both liquids and bubbles within those liquids. We couple to that a sound generation engine capable to the fluid simulator capable of extracting the pertinent information from the bubbles in the liquid and generating appropriate sounds.

Two bubble rising to the surface with different radii. The larger bubble, as predicted mathematically, creates a lower frequency sound.
The two smaller bubbles each generate their own sound, then merge to form the larger bubble, generating a lower frequency sound due to the larger radius.
Water boiling. Manny bubbles are created, deleted (as they reach the surface) and merge, demonstrating the various possible sounds that can be generated using our method.
