Abstract

Eine schalldämpfende Vorrichtung (1) ("Schalldämpfer") für Lüftungsanlagen umfasst ein Gehäuse (2), in dem ein Strömungsweg für Zuluft und ein Strömungsweg für Abluft vorgesehen ist. In dem Gehäuse (2) sind zwei Volumenstromregler (9), zwei Schalldämpfer (10) und ein Nach-Schalldämpfer (20) untergebracht. Der Nach-Schalldämpfer 20 weist mehrere Schalldämpfelemente (21) auf. Die Schalldämpfelemente (21) sind einerseits Anschlüssen (15) für das Zuführen von Zuluft in zu belüftende Räume und anderseits Anschlüssen (16) für das Abführen von Abluft aus zu entlüftenden Räumen zugeordnet. So wird das Übertragen von Schall, wie Telefonieschall, aus einem Raum in einen anderen Raum über die Vorrichtung (1) reduziert bzw. eingeschränkt.A sound-absorbing device (1) ("silencer") for ventilation systems comprises a housing (2) in which a flow path for supply air and a flow path for exhaust air are provided. Two volume flow controllers (9), two silencers (10) and a secondary silencer (20) are housed in the housing (2). The post-muffler 20 has a plurality of muffling elements (21). The sound-absorbing elements (21) are assigned, on the one hand, connections (15) for supplying air to rooms to be ventilated and, on the other hand, connections (16) for discharging exhaust air from rooms to be ventilated. The transmission of sound, such as telephony sound, from one room to another room via the device (1) is reduced or restricted.
