The present invention relates to a structure to reduce noise transferred from an impact source (10) of a ship to a living quarter (15). The structure comprises: a vibration-proof member (20) which is installed on the bottom surface of the impact source (10); a cofferdam (30) which is installed between the impact source (10) and the living quarter (15); and a sound absorbing member (40) which is installed between the cofferdam (30) and the living quarter (15). Thus, the present invention reduces the transfer of airborne noise and structure-borne noise generated by impact from the impact source, such as a container loading place of a ship, to the living quarter, thereby maintaining the enough sound absorbing performance of the lower living quarter.

    본 발명은 선박의 충격원(10)에서 선실(15)로 전달되는 충격소음을 감소하는 구조에 있어서: 상기 충격원(10)의 저면에 설치되는 방진재(20); 상기 충격원(10)과 선실(15) 사이에 설치되는 코퍼댐(30); 및 상기 코퍼댐(30)과 선실(15) 사이에 설치되는 흡음재(40);를 포함하여 이루어지는 것을 특징으로 한다. 이에 따라, 선박의 컨테이너 적재소와 같은 충격원에서 하부의 선실에 이르기까지 충격으로 발생하는 공기음 뿐아니라 고체음의 전달을 저감하므로써 하부 선실에 충분한 방음성능을 유지하는 효과가 있다.
