控制噪聲暴露的建議與措施
通則
為降低船上噪聲，以符合或低于噪聲級規定，應仔細考慮這些降低噪聲的方法。本建議是這方面為船舶設計提供的指導性措施。
噪聲控制措施的設計及構造應在船舶技術設計中予先考慮。
在采用噪聲控制措施中，其消聲材料采用應不引起著火或有害健康的材料、材料應經法定檢驗機構認可。
噪聲源的隔離
2．1、起居處所的位置，在水平或垂直兩方向上均應實際可能遠離噪聲源，如螺旋漿和推進裝置。
2．2、如實際可行，機艙棚應布置在包含有起居處所在內的上層建筑和甲板室的外部。否則，應在機艙相同與起居處所之間布置通道。
2．3、、如實際可行，起居處所應考慮布置在甲板室內，而不應該布置在延伸至船弦的上層建筑內，上層建筑內每層甲板起居處所的縱橫、艙壁上下應盡量對準連續以減少震動。
2．4、如適合，也可考慮以空閑處所、衛生間和洗滌間把起居處所與機器處所隔開。
2．5、一個處所。例如機器處所被分為有噪聲（不經常有人）和較少噪聲（可經常有人）的處所，則有完全隔離層。其艙壁和甲板頂、甲板面應裝有隔聲材料。
3、進排氣消聲
3．1、內燃機排氣系統，機器處所、起居處所和其他處所的送風系統的布置應使進風或排出口遠離經常有船員逗留的區域。
3．2、為使起居處所噪聲級減至小，一般必須把來自機艙棚，艙壁等的排氣系統和某些管路布置及管道布置隔開。如可設專門的通風管道室和電纜通道室。
4、起居處所的控制
4．1、為降低起居處所噪聲級，可能必須考慮甲板室的隔離，其中包括這些處所用彈性安裝的方法與其他結構隔離。如在甲板地坪設浮動地板。
4．2、也可考慮在起居處所內，對艙壁、襯板和天花板提供彈性接頭以及安裝浮動地板或甲板敷料加厚。其安裝襯板的鋼質底槽不宜與甲板接觸，以減少噪聲傳遞。
4．3、對舷窗和窗配備窗簾，并在起居處所內使用地毯，將有助于吸收噪聲。
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.
