Abstract

The invention provides a shock-absorption noise-reduction structure in a ship cabin. A plurality of elastic hanging members are arranged on an upper deck; lower ends of the elastic hanging members areconnected to a ceiling; a floor is arranged on a lower deck; a bottom groove is formed in the floor; a top groove opposite to the bottom groove is formed in one end of the ceiling; a cabin wall boardis arranged between the top groove and the bottom groove; sound-insulation shock-absorption pads are symmetrically arranged on two ends of the bottoms of the elastic hanging members; a supporting plate is arranged on one end near the cabin wall board, of the floor; a sound insulation pad is arranged between the supporting plate and the floor; and the floor includes an anti-skid layer, a dressinglayer, a ceramic wool plate layer, a sound insulation plate layer, and a latex cement layer from top to bottom. The beneficial effects of the invention are that cabinet shock and noise are greatly weakened or eliminated under the actions of parts such as the sound insulation pad, the sound-insulation shock-absorption pads, and the sound insulation plate layer; the shock-absorption noise reductioneffect is enhanced; and elastic connections can greatly reduce sources generating noise and shock, and then the noise value in the cabin can meet the demand.

Description

technical field [0001] The invention belongs to the technical field of interior decoration of ships, and in particular relates to a shock-absorbing and noise-reducing structure in a ship cabin. Background technique [0002] There are many kinds of equipment in the engine room area of ​​the ship. When the ship is sailing, these equipment will generate vibration and a lot of noise during operation, which seriously affects the working environment in the engine room, the living environment of the living quarters on the deck adjacent to the engine room and other life on board. environment. According to the requirements of IMO and the European Union for the noise value in the cabin of a ship, the volume cannot exceed 55 decibels. Once it exceeds 55 decibels, it will cause adverse effects on the daily life of the crew. In order to improve the crew's rest, dining, entertainment, office and other environments, through the improvement of interior outfitting materials and process meth...
