This paper deals with a new type damping sound-absorptionwedge for ship and its material formulations, damping properties, wedge structure, sound-absorption.
简要介绍了舰艇用新型阻尼吸声尖劈的材料配方、阻尼性能、尖劈结构、吸声性能。
2
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。
3
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.
