Audio modelling physics engines

Well we've been away for a while...and a post with a _fascinating_ title such as this is hardly likely to drag our readers back, but hey. Gotta start again somewhere!
Physics modeling engines have become the norm for graphics in 3D and computer gaming...but only now are people trying to apply the same thing to audio. New Scientist has the lowdown... Some way to go yet I'd say, but judging by how quickly physics engines took off in gaming I'd say this is going to be a big growth area in the next couple of years.
