PROBLEM TO BE SOLVED: To provide a noise control device that the ship position is difficult to catch by the underwater radiation noise.SOLUTION: A noise control device 10 includes: a noise control unit 30 having at least two of sub-control units, namely, a fin inclination control unit 31 to adjust inclination of the fins in-phase with each other installed respectively on both gunwales of a ship, a bubble-generation amount control unit 32 to adjust the bubble amount generating into the water from the ship by a bubble generation unit 52, a main engine noise control unit 33 to change the main shaft rotational speed and the propeller pitch of the ship at the same speed and a noise generation control unit 34 to adjust the noise generated by a noise generation unit 54 installed on the bottom of the ship; and a noise management unit 20 to collectively manage each command to at least two sub-control units based on the noise frequency mode.SELECTED DRAWING: Figure 8
【課題】水中放射雑音から船舶の位置が把握されにくい雑音制御装置を提供する。【解決手段】雑音制御装置10は、船舶の両船舷にそれぞれ設けられたフィンを互いに同相に傾斜を調整するフィン傾斜制御部31、泡発生部52が船舶から水中へ発生させる泡の量を調整する泡発生量制御部32、船舶の主軸回転数及びプロペラのピッチを同じ速力で変化させる主機関雑音制御部33、及び船底に設けられた雑音発生体54が発生させる雑音を調整する雑音発生体制御部34、の各サブ制御部うち2以上のサブ制御部を有する雑音制御部30と、雑音周波数モードに基づいて、2以上のサブ制御部へのそれぞれの指令を一括して管理する雑音管理部20と、を備える。【選択図】図8
