    • The present invention relates to a soundproof duct for vessel propellers by using a resonator which is capable of blocking underwater noise in various frequency bands generated in the propeller as the soundproof duct by using the resonator is covered at the vessel propeller. The soundproof duct is formed in a cylindrical shape to surround the circumference of the propeller formed at the lateral part or the rear part of the vessel, guides the fluid flow according to the rotation of the propeller, and decreases acoustic waves generated when the propeller is rotated as resonators for decreasing resonant frequency are arranged in n×m shape (n, m = natural number except "0") in the inside.
    • 本发明涉及一种用于容器螺旋桨的隔音管道,其通过使用能够阻挡在螺旋桨中产生的各种频带中的水下噪声的谐振器,因为通过使用谐振器的隔音管道被覆盖在船舶螺旋桨上。 隔音管道形成为围绕形成在容器的侧部或后部的螺旋桨的圆周的圆筒形状,根据螺旋桨的旋转引导流体流动,并且减小当螺旋桨是 作为用于降低谐振频率的谐振器旋转的n×m形状(n,m =除了“0”之外的自然数))。
