Abstract
An apparatus for reducing noise in a cabin is disclosed.
Noise reduction device of the cabin according to an embodiment of the present invention is installed in or outside the cabin blocking member for blocking the generation of standing waves in the cabin, and the blocking member to a position for blocking the generation of the standing wave It includes a support for supporting to move.
Description
The present invention relates to a noise reduction device, and more particularly to a noise reduction device of a cabin.
In general, ships are provided with a living quarters equipped with a working space and cooking and sleeping cabins for crew members to live while working, which are arranged in consideration of the engine room and the steering room.
In addition, the residence port is made of an array of cabins (cabin) that is a receiving space, the exhaust noise of the generator engine or the main engine is introduced into the cabin through the side wall of the cabin in the process of discharged to the outside of the ship. The most dominant noise source among these noises is the low frequency band, which causes noise problems in the cabin because the transmission loss is very small.
As shown in FIG. 1, the standing wave L1 of the
However, the cabin provided in the conventional ship is difficult to solve the low-frequency noise problem because the sound absorption rate is very small in the case of low-frequency band, which causes a problem that provides an unpleasant environment for the crew living in the residential quarters while working normally I had.
Embodiments of the present invention seek to provide a crew with a comfortable environment by preventing the generation of standing waves in the cabin and by improving sound insulation performance.
According to an aspect of the present invention, a device for reducing the noise of the cabin, the blocking member which is installed inside or outside of the cabin to block the generation of standing waves in the cabin, the blocking member is the standing wave A noise reduction device for a cabin can be provided that includes a support that can be positioned in a position to block the occurrence of.
In addition, a porous sound absorbing material may be installed on the surface of the blocking member to enable sound absorption.
In addition, the blocking member may be formed of a moving panel that is supported by the support so that the edge is movable.
In addition, the support part may be installed at each of four corners facing each other from the inside of the cabin, and may include a plurality of first guide rails to slidably support the corners of the movable panel.
In addition, the support portion may be installed so as to be horizontal from each of the four corners of the outer surface of the cabin, and may include a plurality of second guide rails for slidably supporting the corners of the movable panel.
In addition, the blocking member is made of a first folding panel foldable in a zigzag, the support portion is installed on the upper side and the lower side in the cabin, respectively, and the top of the first folding panel to expand or fold the first folding panel It may include a plurality of third guide rails for slidably supporting the bottom.
In addition, the support portion is hinged to rotate in an upward direction in the horizontal state on both sides of the upper end and the lower side of the outside of the cabin, respectively, the first and second rotary support end is rotatably coupled to the top and bottom of the blocking member It may include.
In addition, the blocking member is made of a second foldable folding panel zigzag, it can be detachably fixed from the first or second rotation support.
In addition, the blocking member is made of a foldable third folding panel zigzag, the support portion is hinged to rotate in a horizontal direction upward on both sides of the upper end of the outside of the cabin, the third folding panel along the longitudinal direction It may include a rotary rail to support both sides of the third folding panel to be expanded or folded slidably, the hinge coupling portion is formed to be rotated downward in a portion spaced apart from the outer surface of the cabin.
Embodiments of the present invention can provide a comfortable environment for the crew by preventing the generation of standing waves in the cabin and improving the sound insulation performance.
