Abstract

Ein Richtmikrofonsystem (1,29) weist zwei Membrane (5A,5B) auf, die einerseits jeweils über ein Luftvolumen (7A,7B) mit einer von zwei räumlich getrennten Schalleinlassöffnungen (9A,9B) akustisch verbunden sind und andererseits über ein drittes Luftvolumen (11) miteinander akustisch verkoppelt sind, sowie Mittel (13,19A,19B) zum Erzeugen mindestens eines Ausgangssignals des Richtmikrofons (1,25,33) aus der Schwingung einer der beiden Membrane (5A,5B) auf.
