控制噪声暴露的建议与措施
通则
为降低船上噪声,以符合或低于噪声级规定,应仔细考虑这些降低噪声的方法。本建议是这方面为船舶设计提供的指导性措施。
噪声控制措施的设计及构造应在船舶技术设计中予先考虑。
在采用噪声控制措施中,其消声材料采用应不引起着火或有害健康的材料、材料应经法定检验机构认可。

噪声源的隔离
2.1、起居处所的位置,在水平或垂直两方向上均应实际可能远离噪声源,如螺旋浆和推进装置。
2.2、如实际可行,机舱棚应布置在包含有起居处所在内的上层建筑和甲板室的外部。否则,应在机舱相同与起居处所之间布置通道。
2.3、、如实际可行,起居处所应考虑布置在甲板室内,而不应该布置在延伸至船弦的上层建筑内,上层建筑内每层甲板起居处所的纵横、舱壁上下应尽量对准连续以减少震动。
2.4、如适合,也可考虑以空闲处所、卫生间和洗涤间把起居处所与机器处所隔开。
2.5、一个处所。例如机器处所被分为有噪声(不经常有人)和较少噪声(可经常有人)的处所,则有完全隔离层。其舱壁和甲板顶、甲板面应装有隔声材料。
3、进排气消声
3.1、内燃机排气系统,机器处所、起居处所和其他处所的送风系统的布置应使进风或排出口远离经常有船员逗留的区域。
3.2、为使起居处所噪声级减至最小,一般必须把来自机舱棚,舱壁等的排气系统和某些管路布置及管道布置隔开。如可设专门的通风管道室和电缆通道室。
4、起居处所的控制
4.1、为降低起居处所噪声级,可能必须考虑甲板室的隔离,其中包括这些处所用弹性安装的方法与其他结构隔离。如在甲板地坪设浮动地板。
4.2、也可考虑在起居处所内,对舱壁、衬板和天花板提供弹性接头以及安装浮动地板或甲板敷料加厚。其安装衬板的钢质底槽不宜与甲板接触,以减少噪声传递。
4.3、对舷窗和窗配备窗帘,并在起居处所内使用地毯,将有助于吸收噪声。

Suggestions and measures to control noise exposure

General rule

In order to reduce the ship noise, to conform to or below the noise level requirements, should carefully consider the method of reducing noise. The suggestion is that this ship design provides guidance measures.

Noise control measures in the design and construction shall be in ship design to consider.

In the noise control measures, the anechoic material used should not cause fire or harmful to the health of the material, the material should be subject to legal inspection body accreditation.

The isolation of the noise sources

2.1, the living place position, in a horizontal or vertical direction shall be two may be far away from the noise source, such as a propeller and a propulsion device.

2.2, if practicable, engine casing should be arranged in the containing living area lies within the superstructure and deckhouse external. Otherwise, should be in the same cabin with accommodation is arranged between the channel.

2.3,, where practicable, accommodation should consider arranged on deck interior, and should not be arranged in the extending to the ship chord in superstructure, superstructure within each deck longitudinal bulkhead, accommodation spaces should be aligned to reduce vibration of continuous.

2.4, if appropriate, may also be considered in the idle place, toilet and washing of the accommodation and machinery spaces.

In 2.5, a place. For example, the machinery spaces were divided into noise ( often do not have one ) and less noise ( often someone ) place, is preferably complete isolation layer. The top of the deck, bulkhead and deck should be fitted with insulation material.

3, into the exhaust muffler

3.1, internal combustion engine exhaust systems, machinery spaces, accommodation and other places of air supply system arrangement should make the air inlet or outlet from the regular crew stay area.

In 3.2, for the accommodation of noise level is reduced to the minimum, the general must be from the engine casing, bulkhead, exhaust system and some piping and piping arrangement. As a specialized ventilation pipe and cable channel chamber.

In 4, the control of accommodation spaces

4.1, in order to reduce the noise level of the living spaces, may have to consider the deckhouse isolation, including these premises with elastic mounting method with other structural isolation. As in the deck of a floating floor floor.

4.2, may also be considered in the living premises, on the bulkhead, lining and ceiling with elastic joint and mounting floating floor or deck dressing thickening. The installation of liner steel bottom groove is in contact with the deck, in order to reduce the noise transmission.

4.3, for windows and side scuttles equipped with curtains, and within accommodation spaces use carpet, will help to absorb noise.
