Tao, Y., Tew, A. and Porter, S.J. (2003) The differential pressure synthesis method for efficient acoustic pressure estimation. Journal of the Audio Engineering Society, 51 (7/8). pp. 647-656. ISSN 0004-7554
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.
