✦ Synopsis

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 that the source strength of the cube is determined first to yield the same acoustic field as that of the original structure. The solution to the radiated acoustic pressure from this volume distribution of source is well known [1]
