Abstract

Die Erfindung betrifft ein Verfahren für die Maskierung von Schall, eine Steuerungseinrichtung und ein Maskierungssystem für die Durchführung des Verfahrens. Erfindungsgemäß werden mehrere Bereiche in einem Raum im Grundzustand voneinander unabhängig leise zwecks Maskierung beschallt. Das Maskierungssystem umfasst daher Mittel, um Bereiche in einem Raum unabhängig voneinander beschallen zu können. Das Maskierungssystem umfasst ferner Mittel, mit denen in einem Bereich erzeugter Schall registriert und vorzugsweise auch analysiert werden kann. In Abhängigkeit von der Schallmessung bzw. Schallregistrierung und - soweit vorgesehen auch in Abhängigkeit von dem Ergebnis der Analyse des gemessenen externen Schalls - wird die maskierende Beschallung des Bereichs, in dem der externe Schall erzeugt worden ist, reduziert und/ oder die maskierende Beschallung der anderen Bereiche verstärkt. Insgesamt gelingt es so, die Lautstärke von maskierendem Schall im Vergleich zu vorbekanntem Stand der Technik klein zu halten und dennoch sehr zuverlässig in gewünschter Weise zu maskieren.
