Abstract
Classical horn theory calculates the throat impedance to predict the performance of a finite length
horn by using the exit boundary condition that the impedance there is that of a rigid piston in an
infinite baffle. Historically such calculations have not seemed to produce good correlation
between the radiated pressure response in the far-field and the calculated throat impedance. In this
re-examination of horn theory, the throat impedance is calculated for a finite three-dimensional
exponentially-flared horn by the Boundary Element Method representing the hom boundaries by
planar elements. The calculated impedance, for the without and with finite-baffle cas
