고부가가치선의 Unit Cabin Mock-up 을 이용한 캐빈소음 저감 연구
Cabin Noise Reduction using Unit Cabin Mock-up of High Value Ship
- 발행 : 2010.05.11
초록
Unit cabin means room, which is installed in the high value ship such as drill ship and FPSO, after pre-assembled. In order to develop the noise control design for a unit cabin, a variety of acoustic tests such as sound absorption, transmission, and radiated noise measurements were carried out by using the mock-up of living quarter. From the tests, it was found out that the combined noise level of a unit cabin could be dominated by the radiated noise from wall panel in low frequency range and the design guidelines for the noise control of unit cabin were fully established, such as the improvement of sound transmission loss between the cabin and corridor, and radiated cabin noise reduction.
