TABLE III. Back- and forward-scattered pressure amplitudes relative to the incident pressure amplitude i of 131026 for a 50-mm-diam spherical void at 1000-m range for the analytical series-expressed solutio BEM, and scaled to 1000 m for the farfield Kirchhoff approximation. A single, fixed orientation is assume the axis of the subdivided icosahedron used to represent the void in the BEM and Kirchhoff approximatio percentage deviation relative to the analytical solution is given.
