Introduction,fort. The only way to minimize these sometimes ‘adverse’ impacts is to ensure that valid and implementable controls are utilized. These controls will need to be optimized with respect to the acoustic goals, vessel operation, and environment being protected. This means that this control process needs to be integrated into the overall ship design.

Prediction Modeling Methods,g or reciprocating machinery, most vessels have extensive, distributed systems such as piping or HVAC. As discussed in Chap. ., these systems can easily transmit noise to remote, sensitive sections of the vessel.

Underwater Acoustics,y, for high-speed craft, additional sources are flow/turbulence over the hull and appendages, and possibly underwater exhaust. For research and naval vessels, sea-connected systems may be of importance. Underwater vehicles have a slightly different set of sources and transmission paths.

Introduction,m’? Are crew and/or marine life to be considered? Are noise and vibration both to be studied? What is the operating profile of the vessel, and how much time, effort and money will be invested to accomplish a quiet vessel? In the long run, designing, building and operating a quiet vessel will have si

Acoustic Criteria,ase of man-overboard or in-port). Ship-induced noise also affects sea life, sometimes over large distances. Acoustic criteria, or in some cases only ‘guidance’, have been established to limit these impacts. For crew and passengers, noise impacts hearing loss, health, comfort, and performance as a mi

Noise and Vibration Control Program Plan, Pettit 2014). These requirements, which may appear as airborne noise, underwater radiated noise, sonar self-noise, and/or vibration limits, are spelled out in ship specifications. They are becoming more prevalent as detrimental impacts from noise are receiving greater recognition. The impacts range
