In the authors’ previous work, the input acoustical impedance of an axisymmetric horn was obtained through the combination of matrix analysis and dedicated electro-acoustical measurements. This work extends the approach to further refine the derivation of the acoustical impedance and transfer function of several different horns. The results are evaluated against COMSOL modeling and analysis made through the two-microphone method. A one-dimensional matrix model is also used for the horn impedance derivation. Acoustical transfer functions of two different horns are measured and compared with COMSOL modeling results.
