Mufflers can be categorized into the following types: resistive mufflers, reactive mufflers, diffuser mufflers, buffer mufflers, and impedance composite mufflers.

A resistive silencer is a device that uses absorbent materials to reduce noise. When sound waves enter the silencer, the absorbent materials convert some of the sound energy into heat, thereby achieving the noise reduction effect.

The resistive silencer operates based on the principle of acoustic-electric filtering. By appropriately combining different acoustic resistances, acoustic compliance, and sound quality within the silencer, specific frequency noises in the channel can be reflected back to the sound source or significantly absorbed, achieving the purpose of noise reduction.

The diffuser muffler is achieved by creating many small holes in its walls. The airflow, after jetting through these holes, experiences a pressure drop and deceleration to achieve the noise reduction effect.

A buffer muffler is a silencer device that converts pulsating flow into a smooth flow by utilizing the impedance of porous tubes and chambers.

The impedance composite silencer is a combination of resistive silencers. The resistive silencer offers excellent noise reduction for mid-to-high frequencies. The resistive silencer also provides good noise reduction in the mid-to-low frequency range. By leveraging these characteristics and combining the two, the impedance composite silencer achieves effective noise reduction across low, mid, and high frequencies.
