Noise and Vibration Control on Ships
This book provides a guide for the marine community to understand and address the noise and vibration environment associated with ships. Controlling noise and vibration in an effective and optimal manner requires a comprehensive understanding of all the ship systems that are involved in achieving a quiet vessel. While there are numerous published articles addressing various components of shipboard noise and vibration, this represents the first comprehensive book on the subject. Beginning from the basic acoustics of noise and vibration, it builds to more complex considerations in undersea sound, ship design, and compliance. The book provides an understanding of the ‘source-path-receiver’ modelling of shipboard noise and vibration. It delivers an overview of how to select and optimize both noise and vibration control treatments along with design guidance and methods to demonstrate compliance with acoustic regulations. It reflects the knowledge gained by the authors consulting over 40years each on hundreds of vessels, and represents an invaluable resource for ship builders and marine engineers.
Handbook of Noise and Vibration Control

Two of the most acclaimed reference works in the area of acoustics in recent years have been our Encyclopedia of Acoustics, 4 Volume set and the Handbook of Acoustics spin-off. These works, edited by Malcolm Crocker, positioned Wiley as a major player in the acoustics reference market. With our recently published revision of Beranek & Ver's Noise and Vibration Control Engineering, Wiley is a highly respected name in the acoustics business. Crocker's new handbook covers an area of great importance to engineers and designers. Noise and vibration control is one largest areas of application of the acoustics topics covered in the successful encyclopedia and handbook. It is also an area that has been under-published in recent years. Crocker has positioned this reference to cover the gamut of topics while focusing more on the applications to industrial needs. In this way the book will become the best single source of need-to-know information for the professional markets.
Ship Vibration 3
Working and living onboard vessels imposes a series of generally low-frequency mechanical vibrations as well as single-impulse shock loads on the human body. Also, exposure to noise is characteristic aboard vessels. Low-frequency vibrations are created by vessel motions, which are produced by the various sea states in conjunction with vessel speed and point of sail. These motions can result in motion sickness, body instability, interruptions of task performance, sleep interruption and fatigue, increased health risk aggravated by shock loads due to slam and reduced human efficiency. Higher-frequency vibration influences comfort and is often associated with rotating machinery. The imposition of higher frequency vibrations (about 1 to 80 Hz) induces corresponding motions and forces within the human body creating discomfort and reduced human efficiency. With regard to noise, the above can similarly affect exposed humans, notably with sleep interruption and resulting fatigue, discomfort, and reduced efficiency. Also of concern are transient and permanent hearing loss, masking of audible signals, and interruption of speech communication. The concerns related to levels and characteristics of noise and vibration are covered in this and the other titles in the series related to ship vibration and noise control. be granted any of the associated habitability notations, specific noise and vibration criteria must be met. Ship designers in pursuit of these notations often request guidance on how to control levels of noise and vibration in inhabited spaces. As a result, this book has been written. The information presented in this book is intended for guidance only to support vessel designers and operators in controlling vessel noise and vibration in the general case, and more specifically in meeting the requirements of classification society habitability rules.
