基于多孔吸声材料的理论及声学传递矩阵理论，分析了目前广泛应用于汽车排气净化消声器中的陶瓷蜂窝载体的消声机理，给出了其声学传递矩阵，并分析了影响其声学性能的主要因素，对传声损失进行了模拟计算．
Based on the theory of porous sound-absorbing materials and the theory of acoustic transfer matrix, the anechoic mechanism of ceramic honeycomb carriers, which are widely used in car exhaust mufflers, is analyzed. The acoustic transfer matrix is given and the influence of acoustic properties The main factor, the acoustic loss was simulated.
