Revised Helmholtz Integral Equation for Bodies Sitting on an Infinite Plane

抄録

This paper presents a revision of the free-term coefficient in the Helmholtz integral equation for solution of acoustic problems in a semi-infinite medium when an obstacle is sitting on an infinite plane. Both the integral representation of the velocity potential and the Helmholtz integral equation are re-derived with giving correct values for the free-term coefficient when the formulations utilizing either the half-space Green’s function or its approximation are employed.
