Muffler is a kind of device to prevent sound transmission and allow air flow to pass through. It is an important measure to eliminate aerodynamic noise. The muffler is installed in the air flow channel of air power equipment (such as blower, air compressor, boiler exhaust port, generator, water pump and other equipment with high noise at the exhaust outlet) or in the air intake and exhaust system to reduce noise.
There are many kinds of mufflers, but according to the mechanism, they can be divided into six main types: resistive muffler, reactive muffler, impedance composite muffler, micro perforated plate muffler, small hole muffler and active muffler.
The selection of muffler should be based on the requirements of fire prevention, moisture-proof, anti-corrosion and cleanliness, installation space, frequency spectrum characteristics of noise source, natural sound attenuation of system, regeneration noise of system air flow, allowable noise level of room, allowable pressure loss, equipment price and other factors. The general situation is: the greater the muffler's silencing capacity, the greater the pressure loss and price; the same amount of noise reduction, if the pressure loss is smaller, the muffler will occupy more space.
