The Boundary Element Method is a well-known tool to calculate sound radiation of horns. As the BEM is based on the linearized sound field equation, only linear properties of the sound field frequency response, directivity etc.) can be calculated. Besides these linear properties, the nonlinear wave propagation in horns is of great interest. It depends mainly on the shape of the horn and the growth rate of the first narrow part. This paper describes a method to combine the pure linear method BEM with the calculation of nonlinear wave propagation in horns. Simulation and measurement results of different horns are presented and discussed. As first results indicate, this method offers a fast and accurate way to calculate nonlinear wave propagation in horns.
