Abstract

Die vorliegende Erfindung betrifft einen Resonator (1) zur Behandlung von Luftschall, der sich in einer gasführenden Leitung (5) ausbreitet. Der Resonator (1) besitzt einen Resonatorhals (9), der die Leitung (5) mit einem Resonatorvolumen (6) kommunizierend verbindet.
Um den Resonator (1) an schwierige Einbausituationen anpassen zu können, weist der Resonatorhals (9) entlang seiner Längsrichtung (11) eine konstante Innenquerschnittsfläche und eine variierende Innenquerschnittsgeometrie auf.
