On the Far-Field Properties of an Acoustic Horn

Eddie Wadbro

September 2006

This report presents a derivation of an expression for time harmonic acoustic wave propagation in the far field for two and three space dimensions, and includes detailed descriptions of the numerical evaluation of the far-field pattern in some typical situations. The presentation covers all parts required for computing the far-field properties of acoustical devices, and the report is designed to function as a single reference for these computations.
