Abstract

The invention relates to a sound insulation door for a ship's living cabin, and belongs to the technical field of air noise control. The sound insulation door mainly comprises door frames arranged onthe two sides of a cabin door and a door fan hinged on the door frames through hinges. The door fan is composed of three layers of structure, the outer layer refers to an aluminum honeycomb plate, themiddle layer refers to a porous sound absorption material, and the inner layer refers to a galvanized steel plate. The inner, outer, upper and lower layers of the porous sound absorption material arefixedly connected with the galvanized steel plate through the aluminum honeycomb plate through clamping. The door fan of the sound insulation door adopts a three-layer composite structure, and the sound reduction index of the sound insulation door is increased.

Description

technical field [0001] The invention relates to a sound insulation door for a ship's living cabin, which belongs to the technical field of air noise control. Background technique [0002] In the ship classification guideline, there are clear noise index requirements for ship cabins, and the living cabins are places where crew members or staff rest, and the noise index requirements are more stringent. In order to meet the requirements of the noise index of the ship's living quarters, in addition to taking vibration and noise reduction measures for the noise source and transmission path, corresponding measures will also be taken for the receiving compartment: such as laying floating floors on the ground, laying sound insulation panels on walls and ceilings, etc. But what is often overlooked is that the sound insulation effect of the selected cabin door is poor or the sound leakage caused by the poor fit between the door and the door frame makes the external noise enter the liv...
