A first resonator chamber (44) is open towards the flow volume (42) via a first resonator neck (68). A second resonator chamber (46) is open towards the flow volume (42) via a second resonator neck (74). A resonator pipe (52) provides the first resonator neck (68) and the second resonator neck (74).
