  1. ( 4 ) establish the grey model on the basis of the actual sound pressure level of 27000dwt bulk carrier superstructure cabin as a sample and extend the grey model through comparing the prediction values with the actual values, aiming to predict the noise level of superstructure cabin of 74500dwt bulk carrier and 5618teu container ship

    （ 4 ）以27000噸散裝貨船上層建築艙室噪聲的實際測量值為樣本，建立灰色預測模型，通過預測值和實測值的對比分析對模型進行推廣，並分別對74500噸散裝貨船和5618箱集裝箱船的上層建築艙室噪聲進行預測。
  2. The silencer greatly reduces noise level emitted from engine inside the cabin, creating a quiet and tranquil environment

    特強的音量滅聲器大大減低由機器發出的噪音，締造寧靜的環境。
  3. The prediction of the noise level in the cabin and work space at design stage is aiming to make effective measurement to control the noise level in advance to meet the regulations and ship owner ' s needs, which can avoid incidental expanses in the remediation and modification, so as to shorten the period and cut the construction cost of ship. in order to predict the noise levels in the ship superstructure cabin, the two methods are discussed in this paper, such as the grey prediction method and the acoustics analysis in fem method

    如果能在船舶設計開發的初期就能對其艙室、工作空間的噪聲值進行預測，對不滿足相關規范或船東要求的部位提前採取有力的措施，不僅能有效的達到減少艙室噪聲的目的，還能避免在船舶建造完成後因採取補救和改動措施而造成的巨額開銷，從而縮短了造船周期，降低了造船成本。
