Abstract

Die Erfindung betrifft eine Vorrichtung zur Erfassung von Schallquellen in einem Fahrzeug, insbesondere in einem Kraftfahrzeug mit einem Mikrofongehäuse (1) zur Aufnahme einer Mikrofonkapsel, vorzugsweise mit einer Längsachse, die senkrecht zur Schalleintrittsrichtung angeordnet ist. Hierbei nimmt das Mikrofongehäuse (1) wenigstens eine weitere Mikrofonkapsel (14) mit unterschiedlicher Aufnahmecharakterisik auf, wobei mindestens eine Mikrofonkapsel (10) bezüglich der Verarbeitung ihres Aufnahmesignals durch das Aufnahmnesignal der anderen Mikrofonkapsel (14) beeinflußt wird.
