13.3. The Kirchhoff–Helmholtz boundary integral

In the previous section we introduced the Green's function
g ( r | r 0 ) = e j k ( r r 0 ) 4 π ( r r 0 ) ,

which turns out to be a solution of the following inhomogeneous wave equation:
( 2 + k 2 ) g ( r | r 0 ) = δ ( r r 0 ) .

An important principle in acoustics is that of reciprocity whereby the locations of the sound source r 0 and its observation point r are interchangeable. It can be seen ...
