Abstract

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.

Description

technical field [0001] The invention relates to the technical field of ship transportation, in particular to a method for controlling ship noise. Background technique [0002] Ship noise (ships noise) is the uncomfortable sound made by the ship's power machinery (main engine, auxiliary engine, propeller, propulsion system, etc.) and auxiliary machinery (pumps, fans, etc.) during operation. The noise of the ship is related to the safety of the ship. For example, if the noise level on the bridge is too high, it will affect the command. If the noise in the sonar dome is too high, it will seriously affect the normal operation of the sonar equipment and interfere with the detection of underwater targets (reefs, sunken ships, submarines, etc.) ) detection. The underwater noise of the submarine will give the enemy an indication of the detection target, and the noise of the ship will also affect the health of the crew and passengers and the comfort of the environment. [0003] Mos...
