【摘要】 本文利用频响函数的倒数导出了三种评价消声器传声损失（Ｒ）的方法。利用这些方法，可以获得比传统方法更丰富的信息，与传声损失总值一起应用，可完整地评价消声器的声学性能。更多还原

【Abstract】 In this paper, three kinds of methods to evaluate the transmission loss of muffler are developed by using the reciprocal of frequency response function (1/H(f)). By means of the methods, more information can be obtained than by traditional ones. The methods, together with total transmission loss, can be used for evaluating integrally acoustic characteristics of muffler.更多还原
