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. The oscillations in a resonator can be either electromagnetic or mechanical (including acoustic ).
The purpose of a resonator is to cancel out a certain range of sound frequencies. Without getting too scientific, sound is simply a pressure wave emitted at a certain frequency. Like waves in the ocean, sound waves have certain amplitudes (comparable to overall size), a crest and a trough.
an instrument for detecting the presence of a particular frequency by means of resonance. Electronics. a hollow enclosure (cavity resonator) made of conducting material of such dimensions that electromagnetic radiation of a certain frequency will resonate. any …
Resonators. When these sound waves of a particular frequency are bouncing off the interior of a resonator, the peak of a wave would meet the trough of another wave of the same size and essentially cancel each other out; thus eliminating that frequency or drone.
Structure. This type of resonator is designed similar to that of an acoustic resonator, which creates an “exhaust note” that gives the exhaust noise a less annoying and more pleasant tone. The sound can be enhanced by means of adjusting the exhaust note.
Waves canceling inside a simplified muffler. The resonator is designed to work best in the frequency range where the engine makes the most noise; but even if the frequency is not exactly what the resonator was tuned for, it will still produce some destructive interference.
Once in the resonator, the light cannot return to the fiber without somehow changing direction. — Chris Lee, Ars Technica , “Spinning glass ball rejects light from one direction,” 27 June 2018 The resonators , meanwhile, act like antennas, picking up and transmitting ambient radio frequencies.
The resonator is part of your exhaust system, but it is not the muffler. It is sometimes known as a pre-muffler because it is installed in the exhaust system after the catalytic converter and before the muffler. Some cars and trucks have them, others don’t.
The resonator is the unsung hero of your exhaust. Controlling sounds and air flow, they set the tone for your car’s performance and manner too.

resonator – an electrical circuit that combines capacitance and inductance in such a way that a periodic electric oscillation will reach maximum amplitude resonant circuit circuit , electric circuit , electrical circuit – an electrical device that provides a path for electrical current to flow
Exhaust resonators create additional sound waves, which effectively cancel out exhaust system noise. The ability of the exhaust resonator to suppress excessive noise helps vehicles pass emission tests. The exhaust resonator stops chassis rattling, which is the primary cause of contaminated fuel emissions.
