Analysing the Impact on Underwater Noise of Changes to the Parameters of a Ship’s Machinery

Abstract

A ship moving over the surface of water generates disturbances that are perceived as noise, both in the air and under water. Due to its density, water is an excellent medium for transmitting acoustic waves over long distances.
