There are many kinds of dissipative mufflers, which can be divided into channel segment muffler, channel segment muffler, double tube muffler, chamber muffler, honeycomb muffler, diamond muffler, sine wave muffler and cartridge muffler. The principle of dissipative muffler is to use sound resistance to eliminate noise. That is to say, when deriving the calculation formula of sound attenuation, only the contribution of sound resistance to noise elimination is considered, and the influence of acoustic impedance is ignored. In practical engineering, in order to reduce the noise of impedance muffler, sound absorption material is often used to make resistive muffler. This is because when the sound wave passes through the pipe lined with porous sound absorption material, the sound wave will excite the air molecules in the numerous pores in the porous material to vibrate. Part of the sound energy can be used to overcome the friction resistance and viscous force and become heat energy. Generally speaking, the performance of resistive muffler is better at medium and high frequency, but poor at low frequency. However, as long as the thickness and density of sound absorption material are increased properly, and the low void ratio is selected, the noise reduction performance at low intermediate frequency can be greatly improved. The broadband resistance muffler can be manufactured from the specification of muffler.
