In a method for determining positions {p}of transducers {A}of an apparatus, the transducers are assumed to be configured for receiving wave signals from and/or transmitting wave signals to one or more regions {R}of interest in an n-dimensional space, with n=2 or 3. An n-dimensional spatial filter function {circumflex over (&#x3c9;)}(r) is determined, which matches projections {P}of the one or more regions {R}of interest onto an n&#x2212;1-dimensional sphere centered on the apparatus. Then, a density function &#x192;(p) is obtained, based on a Fourier transform &#x3c9;(p) of the determined spatial filter function {circumflex over (&#x3c9;)}(r). Finally, a position pis determined, within said n-dimensional space, for each of N transducers, based on the obtained density function &#x192;(p) and a prescribed number N of the transducers. The invention is further directed to related devices, apparatuses and systems, as well as computer program products.
