AB  - The goal of this work is to review and compare different practical methods to obtain a horn’s acoustical impedance. A new alternative method to obtain horn acoustical impedance is introduced and described. A comparison between several methods of measuring horns’ acoustical impedance and finite element analysis is shown. A one-dimensional matrix model is also used for the horn impedance derivation. The acoustical transfer functions of two different horns are measured and compared with the finite element analysis results. A derivation of the axisymmetric exponential horn’s matrix coefficients is provided.
