AB  - Loudspeakers are widely used in three-dimensional sound field reconstruction systems, but their spatial directivity features are relatively little-known. In this paper, a hemispherical array of 40 microphones was designed and built in order to measure the pressure field radiated by different commercially available loudspeakers. The spatial samples of the acoustic pressure were processed in order to estimate the truncated Fourier-Bessel expansion of the sound field, which allows the reconstruction of the 3D radiation pattern. An analysis of the errors involved in the estimation was also performed with a numerical model of the array.
