How the muffler works:

The muffler uses the appropriate combination of the cavity and the tube to achieve two functions to muffle the sound.

The first is to use the sudden change of the pipe section (that is, the change of the acoustic impedance) to reflect the sound wave propagating along the pipe back to the direction of the sound source so that the sound energy is reflected back to the original place.

The second is to use the reflection of several interfaces to make the original first forward-propagating sound wave return to the original point, and turn back and forward again to propagate forward. This point merges with the second forward-propagating sound wave that has not been reflected, and the two are equal in amplitude and an odd multiple of 180 degrees in phase, so they interfere with each other and cancel each other out.

Muffler (Muffler) is a device that prevents sound from propagating and allows airflow to pass through. It is an important measure to eliminate aerodynamic noise. The muffler is a noise reduction device installed on the airflow passage of aerodynamic equipment (such as blowers, air compressors, boiler exhaust ports, generators, water pumps, and other equipment with loud exhaust ports) or in the intake and exhaust systems device.
