Abstract

Die Erfindung befaßt sich mit der Ausbildung von Schallwänden für Großveranstaltungen. Herkömmlich werden dabei zur Schallwiedergabe eine Vielzahl von großen und schweren Lautsprecherboxen eingesetzt, was aufwendige und teure Konstruktionen zur Aufnahme dieser Boxen erfordert. Daher wird erfindungsgemäß eine segmentierte Schallwand 10 angegeben, welche im wesentlichen flach ausgebildet und außerordentlich leicht ist. Werden mehrere dieser Segmente 11' in einer Schallwand 10 integriert, indem die verschiedenen Segmente 11' gekoppelt miteinander verbunden werden, kann die gesamte Größe der Schallwand 10 zur Schallabstrahlung ausgenutzt werden, ohne daß weitere Schallquellen im Abhörraum 31 notwendig werden. Die Optimierung der verschiedenen Segmente 11' aufbestimmte Frequenzbereiche kann dadurch herbeigeführt werden, daß die jeweiligen Segmente 11' auf die entsprechenden Übertragungsfrequenzen abgestimmte Flächen- und Tiefenausdehnungen haben. Durch die Aneinanderreihung mehrerer Schallwände 10 die auf die jeweiligen Bedingungen im Abhörraum 31 sehr flexibel reagiert werden. Außerdem können die dem Abhörraum zugewandten Wiedergabeebenen 30 dieser Schallwände 10 beispielsweise durch entsprechende Aufdrucke als Werbeträger genutzt werden.
