(Summary description)The mass of air in the exhaust pipe muffler pipe is equivalent to the electrical inductance and resistance, which is called sound mass and sound resistance. The volume of air in the cell is equivalent to the electrical capacitance and is called sound compliance. Similar to electrical filters, each cell with a tube has its own natural frequency. When sound waves containing various frequency components enter the first short tube, only certain frequency sound waves near the natural frequency of the first mesh can pass through the mesh to reach the second short tube mouth, while other frequencies Sound waves cannot pass through the mesh. It can only reflect back and forth in the small room, so we call this structure that has a filtering function for sound waves an acoustic filter. Select appropriate tubes and chambers for combination. You can filter out noise of certain frequency components.
