Description

[0002] Automobile muffler is a very important part of automobile accessories. Its main function is to improve driving and riding comfort by reducing the noise generated when the engine is working.

[0003] The working principle of the car muffler is to use two pipes of different lengths in the pipeline. When the sound waves pass through these pipes, the difference in length between the two pipes is equal to half the wavelength of the sound waves emitted by the car, so the two sound waves interfere with each other when superimposed, cancel each other out, thereby reducing the sound intensity and the sound emitted. This interference silencing effect reduces the sound and achieves the effect of silencing. In addition, the internal structure design of the muffler can also play the role of internal silencing, for example, by filling sound-absorbing materials around the pipe to absorb sound energy, the purpose of further silencing is achieved.
