Background

The silencer is used for the airflow pipeline with noise transmission, and can attenuate or reflect the noise in the pipeline by using noise reduction devices such as pipelines and elbows with sound absorption linings or pipelines with suddenly changed sectional areas and other discontinuous acoustic impedances. The former is called resistive muffler, the latter is called reactive muffler, and there are also impedance compound mufflers.

In order to reduce the sound of exhaust gas from an engine in a vehicle, a multi-chamber resistive muffler is generally provided in an exhaust passage of the engine. Resistive mufflers primarily utilize porous sound absorbing materials to reduce noise. The sound-absorbing material is fixed on the inner wall of the airflow channel or arranged in a pipeline according to a certain mode, and then the resistance silencer is formed. When sound waves enter the resistive muffler, a part of sound energy is rubbed in pores of the porous material and converted into heat energy to be dissipated, so that the sound waves passing through the muffler are weakened.
