The relationship between muffler performance and material
Resistive muffler is a kind of equipment used in many equipments. It is an effective device that uses sound-absorbing materials arranged on the inner wall of the pipe or other sound-absorbing structures to achieve the purpose of sound attenuation.
For example, relying on the pores of effective sound-absorbing materials can allow sound waves to cause air and material vibrations in these pores of appropriate size, so specific friction and viscous resistance are generated, and the sound energy is converted into heat energy, which can be absorbed or Exhaust, so that the noise that propagates along the pipeline can be used to attenuate, and the effect of normal noise reduction can be achieved.
Judging from the current use situation, the resistive muffler has a very good muffling effect for mid-frequency noise and high-frequency noise. If there are any factors that may affect the performance of this resistive muffler, then It depends on the specific sound-absorbing material used, and the specific thickness and density of the sound-absorbing layer, as well as the shape and size of the air flow channel section, and the speed of the air flow are directly related to the length of the muffler.
That is to say, the better the sound-absorbing material is used and the thickness is up to the standard, the sound-absorbing performance effect should still be good. It should be known that the sound-absorbing performance of the sound-absorbing material is usually expressed by the sound absorption coefficient, that is to say, the material The greater the ratio of the absorbed sound energy to the incident sound energy, the better the sound absorption performance.
Generally speaking, this kind of resistive muffler can be tubular, sheet-shaped, honeycomb, folded plate, acoustic flow, small chamber and elbow shapes, depending on your use environment. What kind of it is, and then find a suitable resistive muffler for your own use.
