Is it feasible? Sure. The limit on this kind of calculation is basically how much detail do we need to add to the environment (i.e., can we make the model) and how high resolution does the sound wave need to be (can we calculate it given finite compute resources).
To get something that roughly sounds like a rock? Not difficult to model or calculate, if we make some reasonable assumptions.
The sound of a wet towel thrown in the water during a hailstorm? Uhhh that's a tough one.
Simulating sound uses classical mechanics governed by the wave equation, which is well-understood. In terms of CPU power, the calculation to propagate a simple sound wave (wavelet) could probably have been done on a TI-89 calculator from high school.
