Abstract

The directivity of loudspeakers mounted on a sound bar with a slender shape is analyzed. Measurements are compared to results obtained with a boundary element method. A good agreement is obtained in the low-mid frequency range. In order to reduce the computing time, a spheroidal analytical model based on a geometrical approximation of the sound-bar is also considered. This approximation holds up to a certain frequency. The spheroid shape produces a more regular sound field pattern.
