Background

Silencers are a device that prevents sound transmission while allowing airflow through, and are an important measure for eliminating aerodynamic noise. The silencer is a device for reducing noise, which is arranged on an airflow channel of air power equipment (such as a blower, an air compressor, a boiler exhaust port, a generator, a water pump and other equipment with high noise at an exhaust port) or in an air inlet and exhaust system. The types of silencers are many, but they can be divided into six main types, namely resistive silencers, resistant silencers, impedance composite silencers, micro-perforated plate silencers, small-hole silencers and active silencers, by devising the silencing mechanism. A lawn mower is a mechanical tool used to trim lawns, vegetation, and the like. And the power system is a conventional internal combustion power system represented by a small gasoline engine or a diesel engine.
