[0002] A car muffler is a specialized device that blocks sound transmission while allowing airflow to pass, preventing and controlling airflow dynamic noise. Traditional front mufflers typically have a Helmholtz resonator connected in front of the muffler. The resonator's natural frequency roughly matches the noise frequency in the engine airflow, thus achieving a noise reduction effect. However, current Helmholtz resonators are large in size and are prone to generating high-frequency noise during actual use.
