Introduction of Genuine Muffler Parts

    A muffler is a noise reduction device for airflow pipelines with noise transmission. It uses pipelines with sound absorption liners, elbows, or sudden cross‑section changes to attenuate or reflect noise. They are divided into absorptive mufflers, reactive mufflers, and impedance composite mufflers.

    There are six main types: absorptive muffler, reactive muffler, impedance composite muffler, micro‑perforated plate muffler, small‑hole muffler, and active muffler.

Noise reduction principles:

1. Sudden changes in pipeline section reflect sound waves back to the source.

2. Reflections between interfaces cause sound wave interference and cancellation.
