Muffler refers to the use of noise reducing devices such as pipes and elbows with sound-absorbing lining or pipes with sudden changes in cross-sectional area and other discontinuous acoustic impedance to attenuate or reflect the noise inside the air flow pipeline that also has noise propagation. The former is called a resistive muffler, while the latter is called a resistive muffler, and there are also impedance composite types of noise reduction.
