This chapter presents the deduction of formulas for the sound field of sources moving above an infinite flat interface between two fluid media, in two and three dimensions. The sources radiate sound with a general time dependence including sound of finite duration. These formulas are obtained through the convolution of the Green’s function of the stationary case and the source function that includes the motion of the source. For the two dimensional case, the second semi-infinite medium can be locally or non-locally reacting, while for the three dimensional case, only a locally reacting medium is considered.

摘要

This chapter presents the deduction of formulas for the sound field of sources moving above an infinite flat interface between two fluid media, in two and three dimensions. The sources radiate sound with a general time dependence including sound of finite duration. These formulas are obtained through the convolution of the Green’s function of the stationary case and the source function that includes the motion of the source. For the two dimensional case, the second semi-infinite medium can be locally or non-locally reacting, while for the three dimensional case, only a locally reacting medium is considered.
