摘  要:
利用等效线路切割法,把并联内插管双室扩张式消声器简化为等效并联线路,得出此消声结构元件的声场传递矩阵,并对该类消声器的插入损失进行Matlab模拟计算。实验表明,这种方法有较好的拟合度,在低中频段内基本能反映消声元件的消声趋势。

摘  要:
An equivalent circuitry incision way was used to simplify parallel expansionary insert-pipe inside of two-room muffler into equivalent parallel circuitry,which could get their transfer matrix,and then based on Matlab,they were simulated and studied to obtain the insert loss.The experiment showed that it is a good fitness way,which could express the depression of sound in low and center frequency range.
