Abstract: There are several ways to obtain the set of frequency responses all around a loudspeaker, the so-called directivity balloon which provides useful knowledge about the loudspeaker radiation behavior. In this paper, a novel method for collecting far-field directivity balloon datasets is presented. This alternative method builds on traditional polar measurements and proved to be practical both in terms of measurement time and equipment set-up. By cleverly combining datasets and by using far-field wave propagation, datasets in cylindrical coordinates are created and then projected on a sphere. Eventually, using a spherical interpolation, the directivity balloon is obtained.
