Abstract: The Boundary Element Method (BEM) is a well known tool in acoustics for the calculation of radiation from vibrating surfaces. When using BEM for the calculation of horn loudspeakers, the horn surface is described by its surface admittance; the connected driver is modeled by the velocity distribution at the common junction of driver and horn. Measurements of the velocity distribution have shown that higher order modes within the horn throat can be excited by the horn driver (presented at the 116th AES convention). On the other hand, a two-port description of the driver together with a plane-wave velocity distribution for the BEM calculation leads to good results. It is investigated to what extend higher order modes at the driver's mouth contribute to the sound radiation.
