The invention provides a resistive silencer and a ship, the resistive silencer comprises a shell, a sound absorption core body and at least one group of Tesla valves, and the shell comprises a cavity; the cavity is filled with a sound absorption core body, and an air inlet cavity and an air outlet cavity are defined by the two ends of the sound absorption core body and the side wall of the shell correspondingly; the Tesla valve is arranged in the sound absorption core body in a penetrating manner, the Tesla valve comprises a conduction end, a blocking end and more than two communication holes, and the conduction end is one end of the Tesla valve and is communicated to the air outlet cavity; the blocking end is the other end of the Tesla valve and is communicated to the air inlet cavity; the communicating hole is formed in the Tesla valve and communicates with the cavity. The resistive silencer can solve the technical problem that characteristic line spectrum noise cannot be restrained, and full-band broadband silencing can be achieved.

    本申请提供一种阻性消声器及船,阻性消声器包括壳体、吸声芯体以及至少一组特斯拉阀,壳体包括腔体;吸声芯体填充于所述腔体内,所述吸声芯体的两端分别与所述壳体的侧壁围成进气腔及出气腔;特斯拉阀穿设至所述吸声芯体内,所述特斯拉阀包括导通端、阻截端以及两个以上连通孔,导通端为所述特斯拉阀的一端,并连通至所述出气腔;阻截端为所述特斯拉阀的另一端,并连通至所述进气腔;连通孔开设于所述特斯拉阀上,并连通至所述腔体。阻性消声器可以解决无法抑制特征线谱噪声的技术问题,可实现全频段宽带消声。
