中文摘要:
      本文在前文的基础上进一步分析穿孔管与主管道垂直交叉时的声传播特性,导出了相应结构声传递矩阵的精确计算公式。文中以一种含穿孔管元件的典型结构为例,阐明了抗性消声器总的声传递矩阵分析计算方法,并作了讨论。
英文摘要:
      Further analysis about acoustical property of the tubular structure containing preforated pipe is investigated based upon anthor’s previous works.In this paper,the perforated pipe is assumed to be perpendicular to the axis of main tube.The rigorous formulas to calculate the acoustic transmission matrix of the structure are derived.For an example to determine the resultant transmission matrix,a practical design of reactive muffler containing units of perforated pipe is demonstrated and discussed.
