The Boundary Element method implemented in a commercial code is used to verify the acoustic directional characteristic in the far field of an arrayable loudspeaker’s horn in comparison with the full space, far field, measured acoustic balloon. A simple model of the full arrayable loudspeaker horn’s splay idealizes each source only by the calculated emission on a flat plane at each horn’s mouth. This approach reduces significantly the BEM’s calculation time with regard to having to model each source by its full geometry. Comparison with the full space, far field, predicted pressure from test data shows good agreement in all the frequency range of interest.
