Acoustic Wave Propagation Simulation

Delay lines can be used to simulate acoustic wave propagation. We start with the simplest case of a pure traveling wave, followed by the more general case of spherical waves. We then look at the details of a simple acoustic echo simulation using a delay line to model the difference in time-of-arrival between the direct and reflected signals.
