2、S Plaza 16855 Northchase Drive Houston, TX 77060 USA Foreword Foreword (1 September 2017) 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 ves
3、sels. 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 h
4、ealth 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 bo
5、dy 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, a
6、nd interruption of speech communication. The concerns related to levels and characteristics of noise and vibration are covered in a series of ABS Guides related to habitability on ships and offshore structures*. To be granted any of the associated habitability notations, specific noise and vibration
7、 criteria must be met. ABS clients in pursuit of these notations have requested guidance on how to control levels of noise and vibration in inhabited spaces. As a result, these Guidance Notes for Noise and Vibration Control in Inhabited Spaces have been created. The information presented in this doc
8、ument is for guidance only, and is intended to support vessel designers and operators in controlling vessel noise and vibration in the general case, and more specifically in meeting the requirements of the ABS Habitability Guides. Adherence to some or all of the guidance in this document affords no
9、guarantee that a habitability notation will be granted. The September 2017 edition of these Guidance Notes incorporates information from the new IMO Code on Noise Levels On-board Ships (IMO Resolution MSC.337(91) and the International Labour Organizations Maritime Labour Convention (ILO MLC). These
10、Guidance Notes become effective on the first day of the month of publication. Users are advised to check periodically on the ABS website www.eagle.org to verify that this version of these Guidance Notes is the most current. We welcome your feedback.
