This paper deals with a new type damping sound-absorption wedge 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。
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.
