Abstract (en)

[origin: DE19741596A1] Converts acoustic signals, received from several microphones (5, 10, 15), into electric output signals. These signals are heterodyned with at least one electric signal phase delayed prior to heterodyning; so that, dependent on location of the coupled microphones, the amplitude of the heterodyne signal for at least one pre-set point (200) lies in a pre-set region. At the pre-set point a sound source (55) transmits acoustic signals
