Ship Noise

Abstract

“Sound” is one of the of the ship identities. Even though sound is not physical characteristic, it affects a lot in ship performances. Since sound can show an identity of the ship and travel at long distance, any ship can be analyzed and distinguished at long distance if their sound can be detected. For modern ship such as tanker, merchant ship or cruiser, sound factor is carefully considered since the process of ship design, material (or machinery) selection and ship assembly to meet the sound characteristic they needed. In modern military, especially navy, submarine, acoustic mine and acoustic torpedo are considered important threats for the surface ships. Sound from surface or sub-surface ship is a very crucial factor for the ship survival. This article will focus on Ship Acoustic (or Ship Noise) which explains about the causes and effect of it. The article also mentions Ship Acoustic (or Sound) Signature, the importance of ship acoustic and how to reduce the acoustic level of the ship to give more understanding about ship acoustic to the reader.
