Some of this energy is transmitted through the ship's structure to the hull where it is transferred into the water. Ships can also radiate sonar energy in an effort to find submarines. Structureborne noise and sonar noise combine to form the underwater radiated signature of the ship. Radiated noise is the acoustic signal detected by passive sonars. read more
