The characteristics of the wedge is that the high sound-absorption coefficient remains under the high water pressure.

此种尖劈的突出特点是在高压下仍保持高的吸声系数。

The results showed that the absorption performance of this kind of absorber is better than normal wedge absorbers in low frequency and it keeps good absorbing performance in high frequency.

仿真结果表明：带有空腔的尖劈吸声器相对普通尖劈吸声器，除保持高频段较好吸收性能外，在低频段吸声系数有显著提高；
