This document discusses acoustic engineering simulation for the marine industries using Siemens PLM software. It begins with an introduction to STS, Siemens' simulation and test solutions business, and its experience in industries like shipbuilding. The rest of the document covers the vibro-acoustic simulation process, including the source-transfer-receiver model, finite element method, boundary element method, and how element size relates to maximum simulation frequency. It provides examples of applying acoustic simulation to problems in ship design like hull radiation, acoustic signatures, propeller noise, and sonar arrays.
