Abstract
A predetermined characteristic of amplification in dependency of the direction (&thgr;) from which acoustical signals are received at two spaced apart acoustical/electrical transducers ( ) is formed in that repetitively a mutual delay signal (A ) is determined from the output signals of the transducers and according to the reception delay at the transducers, one (S ) of the output signals is filtered, thereby the filtering transfer characteristic is controlled in dependency of the mutual delay signal (A ). The output signal of the filtering ( ) is exploited as electrical reception signal (S ).
