It is concluded that:one,the bigger leakage pres- sure,the faster sound pressure decay,and two,the bigger leakage aperture,the bigger breadth of acoustic band-gap, the lower center frequency of acoustic band-gap.

以通过管阵列的泄漏声波信号为对象,分析其经过管阵列传播后的频谱特性,得到声波的变化规律:泄露压力越大,声压衰减的越快;泄露孔越大,声波禁带宽度越大,声波禁带中心频率越低。
