The invention relates to the technical field of ship transportation, in particular to a ship noise control method. A waste gas header pipe is installed between a cylinder waste gas outlet of a diesel engine and a supercharger, low-frequency noise is weakened, high-frequency noise is weakened through a silencer below a deck, noise current is transmitted to the seabed in a radiation mode through a transmission antenna, the probability of being detected is reduced, parameter signals are compared with ship body noise, error noise is obtained, and the noise is detected. The transducer is driven to emit error noise, noise around the ship body below the water surface is counteracted, and acoustic stealth of the ship is achieved.
本发明涉及船舶运输技术领域,具体涉及一种船舶噪声控制方法;在柴油机的气缸废气出口和增压器之间安装废气总管,减弱低频噪声,通过甲板下方的消音减弱高频噪声,利用传输天线将噪声电流以辐射的方式传输至海底,减小被探测的可能性,将所述参数信号与船体噪声作对比,获得误差噪声,通过驱动换能器发射误差噪声,抵消水面以下船体周围噪声,实现船舶的声学隐身。
