Use of Wavelet Transforms in the Study of Propagation of Transient Acoustic Signals Across a Plane Interface Between Two Homogeneous Media
The problem we study can be defined as follows: In three-dimensional space, we consider two homogeneous media — “air” and “water” — separated by plane interface. There is a point source of sound in “air” at height h above the interface. Its emission is given by a function F(t) of time. We are interested in the behaviour of pressure in water, at time t, depth z, and distance r from a vertical line going through the source.
