A predetermined characteristic of amplification in dependency of the direction (.theta.) firm which acoustical signals are received at two spaced-apart acoustical/electrical transducers (1, 2) is formed in that repetitively a mutual delay signal (A10) is determined from the output signals of the transducers and according to the ion delay at the transducers, one (S1) of the output signals is filted thereby the filtering transfer characteristic is controlled in dependency of the mutual delay signal (A12). The output signal of the filtering (14) is exploited as electrical reception signal (S r).
On forme une caractéristique préétablie d'amplification en fonction de la direction ( theta ) d'où proviennent des signaux acoustiques reçus par deux transducteurs (1, 2) acoustiques/électriques distants l'un de l'autre, en déterminant de manière répétitive un signal de retard mutuel (A10) à partir des signaux de sortie des transducteurs et, en fonction du retard de réception au niveau des transducteurs, on filtre l'un (S1) des signaux de sortie, ce qui permet de réguler la caractéristique de transfert du filtrage en fonction du signal de retard mutuel (A12). Le signal de sortie issu du filtrage est ensuite utilisé en tant que signal de réception électrique (Sr).
