dc.description.abstract | Inhabited environment of marine animals such as whales is gradually worse by increase of ocean noise. The greatest cause of the increase of ocean noise has been reported to be ships. Recently, the International Organization for Standardization has established a standard for general requirements for the measurement of underwater radiated noise by ships in deep sea. Three methods, that is, support-vessel deployed, bottom anchored, and remote transmitted, have been introduced as typical hydrophone deployment configurations in this standard. Hydrophone cable as a medium for transmitting acoustic signals detected by hydrophones is used in all these methods. In these methods, the cable is inconvenient to handle to be multiplexed and heavier if the number of hydrophone increases. To solve the disadvantages of hydrophone cable installed, the measuring system without hydrophone cable is developed to measure underwater radiated noise by ships. Here, the developed system is introduced and the measured results of the underwater radiated noise by a ship is discussed.ion has established a standard for general requirements for the measurement of underwater radiated noise by ships in deep sea.
