NKK CUTS CABIN NOISE

A new cabin construction system designed to reduce noise due to excessive vibration is described. Introduced by the shipbuilding division of NKK, Japan, and called the "Rubber Insulator Construction System" it was first applied to the crew's mess room of a new vessel. Preliminary tests using tapping machines (vibration-triggering machines) having proved satisfactory, full-scale sea trials confirmed that the noise level had been reduced by about 12 dB (A) compared with that recorded in the mess room of an untreated vessel of the same type. Since then three further ships have been fitted with the system and, in addition, the lecture room of the Hakuto Maru, a modern training ship delivered to the Institute for Sea Training of Japan's Ministry of Transport, has been rubber insulated, the noise reduction in this case being 10-12 dB (A). Diagrams showing how the rubber is fitted and a method of ceiling (deckhead suspension are included.) Order from BSRA as No. 49,529.
