A friend and I talked about doing this abaout a year ago but nothing came of it.
Some thoughts though, radiosity would probably work better than ray-tracing.
You will need to deal with phase relationships of the sound energy. It isn't 
clear what is needed to model the reflecting surfaces (at least to me). How do
display the results?
