Abstract: A resonator for attenuating sound waves produced by an engine includes a resonator housing and a neck. The neck includes an outer shell extending from the resonator housing providing fluid communication between the resonator housing and an air duct. The neck further includes a partition disposed in the outer shell. The partition cooperates with the outer shell to define a plurality of distinct air paths, each air path in fluid communication with a distinct resonance chamber of the plurality of resonance chambers. The resonator is operable to attenuate or change the characteristics of sound waves produced by the engine.
