本文介绍了一种新型的高强度、高阻尼、耐腐蚀性优良的螺旋桨专用合金在降噪效果方面的试验研究成果。试验结果表明：用这种合金制作舰船螺旋桨，确能有效抑制唱音（共振引起的异常噪声），有明显的降噪效果。
This paper presents a new type of high strength, high damping, corrosion resistance of special propeller alloy in the noise reduction effect of experimental research. The experimental results show that the ship propeller made of this kind of alloy can effectively suppress the singing sound (the abnormal noise caused by the resonance) and has obvious noise reduction effect.
