Abstract

A differential pressure synthesis (DPS) method is proposed which estimates the free-field acoustic pressure on the boundary of an object from its geometry by precalculating a database of pressure changes caused by introducing orthogonal shape deformations to a template shape. Pressures are synthesized using DPS for a two-dimensional shape and a three-dimensional KEMAR head model. The accuracy of pressure estimates compares favorably with the boundary-element method computation provided that shape deformations are moderate in relation to acoustic wavelength.
