Abstract

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