Muffler introduction

The muffler means that the airflow pipe with noise propagation can be attenuated by a noise reduction device such as a pipe and an elbow with a sound absorbing lining or a pipe with a sudden change in cross-sectional area and other acoustic impedance discontinuities, so that the noise in the pipe is attenuated or Reflect back. The former is called a resistive muffler, the latter is called a resistance muffler, and there is also an impedance compound muffler.
