Not exactly directly related to the original question, but to feed the 
discussion and curious minds regarding sound waves also in games, I 
thought to share that Intel just recently published a paper on this.

Interactive Geometric Sound Propagation and Rendering

"
*Abstract*

We describe a novel algorithm and system for sound propagation and 
rendering in virtual environments and media applications. Our approach 
uses geometric propagation techniques for fast computation of 
propagation paths from a source to a listener and takes into account 
specular reflections, diffuse reflections, and edge diffraction. In 
order to perform fast path computation, we use a unified ray-based 
representation to efficiently trace discrete rays as well as volumetric 
ray-frusta. Furthermore, our propagation algorithm scales well with the 
number of cores, and uses interactive audio rendering technique to 
generate spatialized audio signals. The overall approach can render 
sound in dynamic scenes, allowing source, listener, and obstacle motion, 
and we show its performance on game-like and architectural environments. 
To the best of our knowledge, this is the first interactive sound 
rendering system that can perform plausible sound propagation and 
rendering in dynamic virtual environments.
