This paper is fundamentally wrong. The major mistake is the replacement of Eq. ( 1) by ( 3). The authors intend to replace the acoustic field radiated by an arbitrary structure by that of a cube with uniform source distribution inside the real source surface. This substitution will be fine, provided

A new numerical method, the boundary point method, used for calculating the acoustic radiation problem caused by a vibrating body is presented. The gist of the new numerical method is to replace the coe$cient matrices [A] and [B] in the system equation with the particular solution matrices which are
