Abstract

Die aktive Geräuschunterdrückung für eine lärmabstrahlende Fläche weist mindestens zwei achsenselektiv integrierende Schnellesensoren auf, welche Schwingungen der Fläche in mindestens zwei, im wesentlichen orthogonale Richtungen erfassen und über eine Regelung einen auf die Fläche wirkenden Aktuator ansteuern, derart, daß den Auslenkungen der Fläche entgegengewirkt wird.
