I think you're not going to get too far here.  I'm looking at
Theoretical Acoustics by Morse and Ingard, and solutions to the 2D
acoustic equations involve quite a bit of calculus. Some of them don't
have closed-form solutions. Acoustic wave equations are much more
difficult to calculate than heat transfer equations.
