Resistant muffler structure: Usually contains components such as expansion chambers and resonance cavities. By changing the cross - sectional area of the air flow channel, phenomena such as reflection and interference of sound waves occur during the propagation process, thus consuming sound energy.
Resistive muffler structure: It is filled with high - temperature - resistant sound - absorbing materials inside, such as ceramic fiber, glass wool, etc. When sound waves pass through, they interact with the pores of the sound - absorbing materials, and the sound energy is converted into heat energy and absorbed.
Composite muffler structure: Combines the resistant and resistive muffler structures to form a resistance - jet - absorption composite muffler. This type of muffler has the advantages of both, has a wide muffling frequency band, can effectively reduce noise within a relatively wide frequency range, and can withstand high - temperature and high - pressure air flow environments.
