Abstract
An acoustical beam former is proposed with at least two acoustical/electrical converters ( ) in a predetermined physical distance. The mutual phasing of the output signals of the two converters is detected ( ) and is multiplied by a constant or frequency-dependent factor. In dependency ( ) from multiplied phasing and from at least one of the output signals of the converters ( ) there is generated an electric output signal which has a dependency from spatial impinging direction of acoustical signals to the converters ( ), as if the two converters were located at a virtual distance from each other which is different and especially considerably larger than the real physical distance they are mutually located.
