A standing wave in a rectangular cavity resonator. A resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonant frequencies, with greater amplitude than at others.esonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal. Musical instruments use acoustic resonators that produce sound waves of specific tones.
Much like a muffler, a resonator is dimensioned to reduce the noise from the engine as the exhaust gases pass through its chambers. Adding a resonator to your existing exhaust system can not only give your car a sporty sound, but it can reduce the raspy sound of the exhaust as well.
