摘要
本文通过声波在穿孔声管中传播特性的研究,导出了声波在穿孔声管中传播的声场传递矩阵。文中运用插入损失的定义,建立了消声器消声性能的数学模型,并在实验验证基础上,分析了各种参数对穿孔声管消声器消声性能影响的变化规律。
The sonic field transmission matrixes of perforated absorbent pipe is given after the transmission performance of perforated pipe is studied. Based on the defination of insortion loss, the mathematic model of muffler is set up in this paper, the tendency of accoustic performance of perforated absorbent pipe with different parameters is analysed through verify consistency of theory and experiment.
