  & nbsp; & nbsp; Muffler is a device used to reduce noise, widely used in engines or exhaust systems of vehicles such as cars, airplanes, and trains. The following is a detailed introduction to mufflers: 1. Basic Overview:   & nbsp; & nbsp; A muffler is a device that prevents sound propagation and allows airflow to pass through, usually installed on the airflow channel of aerodynamic equipment or in the intake and exhaust systems.   & nbsp; & nbsp; Its main function is to control noise and eliminate aerodynamic noise, commonly used in automobile exhaust, air compressor intake, ventilation ducts, high-pressure steam and gas emissions. 2. Main types:   & nbsp; & nbsp; Resistive muffler: uses sound-absorbing materials to absorb the energy of noise, thereby reducing noise. Suitable for eliminating mid to high frequency noise, such as engines, blowers, etc.   & nbsp; & nbsp; Resistance muffler: By changing the length and cross-sectional area of the pipeline, the direction of sound wave propagation can be altered to reduce noise. Suitable for eliminating low-frequency noise, such as the noise generated by the air intake and exhaust of transportation vehicles such as subways and trains.   & nbsp; & nbsp; Microperforated plate muffler: made of microperforated plate, with wideband noise reduction performance. Suitable for high temperature, humid environments with water, oil mist, and particularly clean and hygienic conditions.
