Abstract

Es wird eine Schallaufnahmeeinrichtung für eine Sprechstelle beschrieben. Von einer Schallquelle aus wird Schall abgegeben und von wenigstens zwei Schallaufnehmern (2) aufgenommen und in elektrische Signale umgewandelt. Die Schallaufnehmer (2) sind in einem Abstand zu einer Bezugsposition (1) angeordnet, die der Ideal- oder Sollposition der Schallquelle entspricht. Richtungsvektoren (4) zwischen dieser Bezugsposition (1) und den jeweiligen Schallaufnehmern (2) zeigen in unterschiedliche Richtungen. Die Schallaufnehmer (2) sind elektrisch oder akustisch mit einer gemeinsamen Additionsvorrichtung (6) für die Amplituden der Signale verbunden.
