The Differential Pressure Synthesis Method for Eastimating Acoustic Pressures on Human Heads
Differential pressure synthesis (DPS) estimates the free field acoustic pressure on the boundary of an object from its geometry. The DPS method pre-calculates a database of pressure changes caused by introducing orthogonal shape deformations to a template shape. Pressures on the object are synthesised by summing weighted pressure components from the database. Given an appropriate template, the accuracy of DPS approaches that of the proven boundary element method (BEM). Yet computationally its performance is much closer to that of simple spherical head approximations. Pressures are synthesised for a 2D shape and a 3D KEMAR head model and are compared with those from direct application of the BEM. Applications and constraints of DPS are discussed, including its potential for the rapid estimation of head-related transfer functions.
